K.T. 3B) resolved ambiguities in favor of the character state that had a higher negative log likelihood than the competing character states, and was better in the sense that it avoided inclusion of the same datapoint in frequencies of multiple character state paths. Ecologically biased extinctions may especially produce a very different pattern of character state evolution compared to scenarios in which extinctions may be completely random. 1C–F), with a broad distribution including subtropical China and Japan, is considered to mimic ‘white spot models’, including P. aristolochiae (white form, Fig. Then, I map the diversity of mimicry types to test their evolutionary directionality, including gains, losses, and transitions between mimicry types. Mimicry in butterflies is a complex adaptation, possibly involving supergenes and dramatic coding and regulatory changes in a number of genes, each with multiple alleles (Fisher 1958; Ford 1965; Sheppard 1975; Koch et al. Approximately, 25% of ∼200 Papilio swallowtail butterfly species are mimetic, with independent origins of mimicry in several species groups (Zakharov et al. (Princeton University Press, New Jersey, 2014). Article  For modelling Batesian mimicry, the two most developed systems are both swallowtail butterflies from the genus Papilio: P. memnon from South East Asia. And we see that about 25% of the approximately 200 species of swallowtail butterflies are mimics. These subgenera have a large number of mimetic species and contain taxa that have fueled research on mimicry and natural selection for over a century. Of these, aposematism and mimicry1,2 (Box 1) are phylogenetically … These results indicate that the white spot size in the mimetic females can change in response to natural selection. Publisher's note: Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. 2006), could test the directionality and pathway models of Batesian mimicry. The character state changes in these traits would be captured as one‐step evolutionary transitions on species‐level phylogenies, as state changes 0→1 from ancestors A to B. If you do not receive an email within 10 minutes, your email address may not be registered, Clearly, it would be worthwhile designing new sets of experiments to investigate whether intermediate rates of asymptotic predation on natural prey exist, and, if so, how common they … This provides us with another fortunate opportunity to directly observe the presumable micro-evolutionary change in the mimetic wing colour patterns. There is little understanding about the organization of mimetic diversity and the evolutionary paths that different mimicry types follow. and Toshiki Hatano for access to specimens, and Kaori Tsurui and Atsushi Honma for discussion and comments on the manuscript. The internal nodes connecting the ancestors of these female‐limited mimics to P. achisiades and P. erostratus are unresolved. A single origin of Batesian mimicry among hybridizing populations of admiral butterflies (Limenitis arthemis) rejects an evolutionary reversion to the ancestral phenotype. The viceroy butterfly exhibits visual mimicry as a defensive mechanism. This might imply that traits that face intense selection in both sexes have a very high rate of evolutionary change, and that such traits may evolve at microevolutionary scales. The increased variance of the white spot size of mimetic P. polytes after the arrival of P. aristolochiae can be explained by disruptive selection due to the presence of two models, one with and the other without a white spot. The wing colour pattern of P. aristolochiae (Fig. PubMed Central  & Takeuchi, Y. From this analysis I conclude that directionality is indeed evident in various Batesian mimicry types in Papilio. Nonetheless, I have included the above mimicry types in Papilio under Batesian mimicry. Vane‐Wright, in fact, believed that species‐level phylogenies, which capture speciational patterns in wing color evolution (cf. Testing it requires some creativity. A genetic mechanism for female-limited Batesian mimicry in Papilio butterfly. The resultant frequency histograms of character state changes across the Papilio phylogeny, depicted in Figure 3, were generated with the following rules. Linn. In the swallowtail butterfly Papilio polytes, only mimetic-form females resemble the unpalatable butterfly Pachliopta aristolochiae. Frequencies of character state paths on the y‐axis are derived empirically from Figure 2 using a maximum likelihood criterion with a decision threshold value of either T= 2 (A), or T= 1 (B). 507, 229–232 (2014). The genetical theory of natural selection. How could we explain this lack of evidence for the loss of mimicry, when mimicry is expected to be lost frequently? Clarke, C. A. Females of each morph of P. polytes are morphologically differentiated in closely resembling sympatric unpalatable butterflies6. Learn more. Proc Biol Sci. Contrary to his expectation, P. erostratus has followed a different two‐step evolutionary path, as follows. This includes P. polyxenes, in which caterpillars are aposematic but adults are palatable and female‐limited Batesian mimics of Battus philenor (Brower 1957; Codella and Lederhouse 1989). The dashed line is the regression of the white spot size before the new model’s settlement (1961–1991); the solid line is the regression after the new model’s settlement (1994–2016). This species has a female-limited polymorphism in Batesian mimicry, in which females exhibit four morphs (forma cyrus, f. polytes, f. romulus and f. theseus), whereas males are always monomorphic within a population6, 10. 2006) or stasis in wing color patterns. Thank you for visiting nature.com. One might argue that this trend is an artifact of missing taxa: if the Papilio phylogeny included all species, the monomorphic mimetic links between monomorphic nonmimetic ancestors and female‐limited descendents would indeed be discovered. These various wing colour patterns suggest that regionally different predation pressures related to differences in model morphology drove micro-evolution towards better mimicry in each region. M.K.

However, our analysis indicates that the white spot size is only maternally inherited, and thus the white spot size variation in the studied population is not controlled by an autosomal gene. Nonetheless, the patterns presented above seem robust and will most likely persist when a denser Papilio phylogeny based on more gene sequences is available. (B) Change in the white spot size of f. polytes in the Miyako group (red dot: including Miyako and Irabu islands) and the Yaeyama group (blue dot: Ishigaki, Hateruma and Iriomote islands). Mitsuho Katoh or Kazuki Tsuji. Note that not all mimetic Papilio have been experimentally demonstrated to be Batesian mimics. Remarkably, the timing seemed to differ from that on Okinawa, with a more prominent increase in size before 1992 (b = 0.111, P = 0.172) than after 1993 (b = 0.006, P = 0.885), although neither was significant (Fig. The evolution of dimorphic mimicry, however, appears to have followed unexpected character state paths. R. Developmental Core Team. Why would one expect such diversity of and directionality in mimicry types? 56, 836–840 (2002). Article  Batesian mimicry is known to occur across animals and plants through different sensory modalities, but visual signals are the best known and understood (Cott, 1940). https://doi.org/10.1038/s41598-017-06376-9, DOI: https://doi.org/10.1038/s41598-017-06376-9, Ecological Research 2006; Ceccarelli and Crozier 2007; Kunte 2008; Prudic and Oliver 2008). I chose to map these six mimicry types because they are represented in the current phylogeny by at least one example. Hence, it was erroneous to conclude that mimicry was ancestral in this species and that arthemis had lost it. Distribution of mimicry types among Papilio butterflies. 47, 405–409 (2015). 78, 1029–1036 (2009). Sci Rep 7, 6369 (2017). This might suggest that the rate of evolutionary change toward sexually dimorphic traits may potentially be more rapid than current models predict. Recent observational and experimental evidence showing that sexually dimorphic traits may evolve or be enhanced rapidly within a few generations (Badyaev 2005; Chenoweth et al. If the situation was reversed so that most of the butterflies attacked were palatable, the mimicry bluff would fail. One very famous example of Batesian mimicry which was being cited for many years was the one between the viceroy butterfly and the monarch butterfly. In the present analysis, I did not account for female‐limited mimetic polymorphism because a previous analysis has specifically dealt with it (Kunte 2008). See more. Mark Salvato Chapter 28 Most Spectacular Batesian Mimicry 69 The swallowtail butterfly, Papilio dardanus , oc-curs throughout most of Africa. Ford, E. B. Ecological Genetics, 4th ed. analysed the data. (A) A Papilio polytes male and (B) a P. polytes f. cyrus non-mimetic female, with basically the same wing colour pattern. 3B) demarcated as follows. If you find something abusive or that does not comply with our terms or guidelines please flag it as inappropriate. Schoener, T. W. The newest synthesis: understanding the interplay of evolutional and ecology dynamics. The numbers on the x‐axis correspond to the numbered theoretical character state paths in Figure 1. More recently, studies have shown that Viceroys can be quite unpalatable and that some populations of Monarchs can be tasty to birds. Their wing morphology is characterized by many small red spots on the black hind wings. What Is Batesian Mimicry? 3A, n= 69 with T= 1 in Fig. Here, I present a version of character state paths model that is modified to study the evolution of Papilio mimicry types using phylogenetic methods. Thus, for female‐limited mimicry to evolve from an ancestral monomorphic nonmimetic species, the two‐step evolutionary series of state changes 0→1→2 might follow the sequence of the ancestor–descendent species relationship in a lineage: A→B→C, with A being a monomorphic nonmimetic (state 0) ancestor and B being its descendent with monomorphic mimicry (state 1), which may in turn give rise to C, a female‐limited mimic (state 2). Among specimens collected between 1961 and 2016, the average white spot size was unchanged before the model’s arrival but has rapidly increased since then. The second approach of using T= 1 (Fig. Over time, the white spot size approached the model’s range (Fig. As shown, however, there is a large variation in wing patterns among f. polytes females. The empirical relative frequencies of state paths in Figure 3 are sensitive to tree topologies; hence, their distributions will change slightly based on specific tree topologies used, just as they change slightly when different decision threshold values (T) are used to reconstruct ancestral states (Figs. To answer these questions, I present a graphical model that connects various mimicry types by hypothetical character state changes within a phylogenetic framework. The sequence of these paths is in fact rare, while state path 10 is common in Papilio. Batesian mimicry, in which palatable species gain protection from predators due to their resemblance to aposematic species, is common among insects (Wickler 1968; Rettenmeyer 1970). Fukuda, H. Why did six butterfly species expand their ranges northward in the Nansei Islands? One of the main findings of this article—that although the evolution of Batesian mimicry is prevalent in Papilio, its loss is not evident—is remarkable. (C–F) P. polytes f. polytes resembles (G) Pachliopta aristolochiae. The white spot size was inherited only maternally, with heritability exceeding 1 (Table 1). Papilo troilus shows yet another character state path to dimorphic mimicry: that of a one‐step change from sexually monomorphic nonmimetic wing coloration directly to dimorphic mimetic coloration. The internal nodes in Figure 2 represent proportional maximum likelihoods of various ancestral mimicry types. Because the mimicry is a female-limited trait, we used grandmother–granddaughter regression to estimate the heritability of spot size, separately analysing paternal grandmother–granddaughter (for estimation of narrow-sense h Two important patterns are evident from these analyses. The images or other third party material in this article are included in the article’s Creative Commons license, unless indicated otherwise in a credit line to the material. Polymorphic mimicry is represented in the present Papilio phylogeny solely by P. clytia, which has two mimetic forms that are shared between the sexes (Fig. The term has sometimes been used loosely to include cases where an animal, most frequently an insect, bears a strong and often most remarkable resemblance to some feature of its inanimate surroundings. Here, I have tried to provide phylogenetic framework and data to test the theories about evolution and diversity of Batesian mimicry types. CAS  The Ryukyu Archipelago, situated in the subtropical region of Japan, lies at the northern end of the species distribution of P. polytes. Cite this article. 10, 20140304 (2014). 2004; Jiggins et al. )” in Mesquite (Maddison and Maddison 2006). Both these studies disfavor Prudic and Oliver's notion of arthemis having lost mimicry. The left wing was used unless it was damaged. Furthermore, there is experimental evidence that birds on Miyako Island that fed on P. aristolochiae started to avoid P. polytes f. polytes It is also possible that in the absence of protected models, mimics that have acquired conspicuous wing color patterns suffer heavy predation aided by their slow flight. Most of the internal nodes were well‐supported, although deeper relationships among some clades were weakly supported. The initial evolution of one mimicry type may facilitate evolution of other mimicry types when selection for mimicry changes, sometimes leading to more complex mimicry types. 2). In these cases, all the state paths that contributed to the proportional maximum likelihood values ≥ 0.85 from the ancestral to the descendent species were included in the dataset following the default setting in Mesquite. (Chapman and Hall, London, 1975). In such cases, we chose 30 points from the clearly white spot area at random with the ‘multi-point’ tool of ImageJ, converted the image to grey scale, and evaluated the brightness value (0–255) of each pixel. Contributions to an insect fauna of the Amazon Valley (Lepidoptera: Heliconidae), Experimental studies of mimicry in some North American butterflies. This explanation is consistent with the fact that before the arrival of P. aristolochiae, mimetic females of P. polytes had smaller white spots on average (Fig. However, some choose to use a dual technique of stealth and signal display, together. The change from this ambiguous ancestral state to the female‐limited mimicry in P. garamas was counted in each of the three possible state paths (state paths 5, 11, and 10). A recent report showed that a single gene, doublesex (dsx), controls this mimicry; howev … Uesugi, K. Temporal change in records of the mimetic butterfly Papilio polytes with establishment of its model Pachliopta aristolochiae in the Ryukyu Island. Mimicry is an adaptive peak that offers relative enemy‐free space; hence the evolution of Batesian mimicry should enhance the life expectancy of mimetic individuals and increase their fitness relative to nonmimetic individuals. There was no significant genetic correlation between the white and red spot sizes (maternal r = 0.152, P = 0.134; paternal r = 0.065, P = 0.351). A change from this ancestral state to female‐limited mimicry in P. aegeus was counted as one character state change following state path 10, and the stasis leading to the monomorphic nonmimetic P. hipponous was counted as one character state change following state path 1. 1). The use of T= 1 slightly affected frequencies of a few character state paths but it did not affect the overall patterns of mimicry evolution in Papilio (compare Fig. http://creativecommons.org/licenses/by/4.0/, https://doi.org/10.1038/s41598-017-06376-9, Idea paper: Airport ecology, an environment without predation pressure drives evolution, Mimicry genes reduce pre‐adult survival rate in So a gene that controls white spot size may exist on the W sex chromosome (lepidopterans have ZW sex determination, in which females are heterozygous) or in organelle genomes. Google Scholar. Figure 2 shows the maximum likelihood reconstruction of ancestral mimicry types on the Papilio phylogeny (–log likelihood = 74.62). 331, 426–429 (2011). Competitive advantage, red‐queen dynamics, or enemy‐free space in adaptive landscapes accompanying such changes are believed to favor such evolutionary directionality in many complex adaptations. Science MATH  2) = 4r M.K. (2004) for further details. On Okinawa, one mimicry model is Pachliopta aristolochiae, which was not present on the island until 1993. The pathway approach and phylogenetic patterns of mimicry demonstrated in Papilio are useful to test novel hypotheses regarding the diversity and evolutionary directionality of Batesian mimicry in other systems. The broad-sense heritability (H Please check your email for instructions on resetting your password. Given the current evidence, I have assumed Papilio to be Batesian mimics. One explanation is that it is an artefact due to the small sample size before 1992: we might have failed to sample outliers before the model’s arrival just by chance. Ellers, J. However, a denser phylogeny is likely to resolve several critical ambiguous internal nodes, particularly those leading to P. erostratus and P. clytia. To compare the trends before and after the new model’s arrival, we performed least squares linear regression analysis for 1961–1991 (before the new model’s arrival) and 1994–2016 (after). A recent report showed that a single gene, doublesex (dsx), controls this mimicry; however, the detailed molecular mechanisms remain unclear. In 1991, Uesugi17 assumed that the model of f. polytes on Okinawa was the unpalatable butterfly Byasa alcinous, a native to the island. Uesugi, K. The adaptive significance of Batesian mimicry in the swallowtail butterfly, Papio polytes (Insecta, Papilionidae): Associative learning in a predator. 2004). Working off-campus? Such type of selection—diversification–extinction dynamics may have driven speciation and wing color pattern diversity in Batesian mimetic butterflies. Thus, these species may be considered Müllerian rather than Batesian mimics (in Müllerian mimicry unpalatable species mimic each other). Thus, the frequency‐dependent advantage of mimicry may direct the evolution of monomorphic mimicry toward polymorphism and female‐limitation, giving rise, in the process, to different mimicry types. and you may need to create a new Wiley Online Library account. The empirical frequencies of these paths were then calculated by ML method (see next section). R: A language and environment for statistical computing. We first analysed red and white spot sizes separately, and then analysed their genetic correlation. Weekly Schedule. Historically, its putative ‘white spot model’ was not distributed in Japan. The absence of the loss of mimicry is significant: there were 14 instances on the Papilio phylogeny in which mimetic ancestors gave rise to descendent lineages. For example, the most recent common ancestor of the species pair P. hipponous and P. aegeus was most likely monomorphic and nonmimetic (proportional maximum likelihood score = 0.975). The former was believed to be harmless, and hence mimicking the latter, which is poisonous for birds and other predators. 11, 36–42 (2004). 2008), lends credibility to this suggestion. In an intriguing proposal, Vane‐Wright suggested that one such adaptation with evolutionary directionality is Batesian mimicry (Vane‐Wright 1971, 1979). Figure 3 presents the empirical frequency of character state changes in mimicry types, drawn from the theoretical character state paths as numbered in Figure 1. (2020), Journal of Evolutionary Biology 2007; Ries and Mullen 2008). This work was supported by a Dorothea Bennett Memorial Graduate Fellowship and a Continuing Fellowship from the University of Texas. I have surveyed the occurrence and mimicry type in every species group in all of Papilio species, and find that this argument would not be true even if all the species were to be included in the Papilio phylogeny. Many animal and insect species use Batesian mimicry -- mimicking a poisonous species -- as a defense against predators. (2020), Ecology and Evolution They lie motionless, waiting for the prey to get closer, and then suddenly exhibit various signs, momentarily distracting the predator and making a run for it! Then a horizontal line crossing landmark 1 was drawn perpendicular to the vertical line. Article  PubMed  Google Scholar. This brings forth an important caveat regarding the use of phylogenetic methods in inferring evolutionary patterns: that of undocumented extinctions. In the swallowtail butterfly Papilio polytes, only mimetic-form females resemble the unpalatable butterfly Pachliopta aristolochiae. Maternal inheritance and rapid evolution of sexual size dimorphism: passive effects or active strategies? A theoretical character state path network showing 16 paths leading to the evolution of common Batesian mimicry types in Papilio swallowtail butterflies. However, there is scant direct evidence of micro-evolutionary change over time in mimicry traits. 1I) is limited to the true tropics, where they share their range with ‘red plain models’ such as Pachliopta aristolochiae (black form) and Pachliopta hector Three of the four North American species include populations which are Bate-sian mimics of distasteful models [11-14].Limenitis arthemis (Drury) includes two populations, L. a. astya- nax … In Batesian mimicry, animals avoid predation by resembling distasteful models. [PMC free article] Prudic KL, Oliver JC. Batesian mimicry is named for Henry Walter Bates, a British scientist who studied mimicry in Amazonian butterflies during the mid- and late nineteenth century. 2) regressions19. On the other hand, caterpillars of most mimetic Papilio, including the largest mimetic radiations in subgenera Menelaides and Heraclides, feed on rutaceaous and related plants with little noxious chemical properties (Anonymous 2009), and species tested so far from these groups have been shown to be palatable to predators (Brower 1957, 1958; Chai 1990; Uesugi 1995). from the Ryukyu Islands, Japan, analyzed by genotyping‐by‐sequencing, Polarization control in a crossed undulator without a monochromator, Microevolutionary change in mimicry? It is named after the English naturalist Henry Walter Bates, after his work on butterflies in the rainforests of Brazil. Such a two‐step evolutionary change would be expected in sexually dimorphic traits as long as the assumptions and conclusions of the current population genetic models regarding the tempo of evolution of sexually dimorphic traits are correct. I used a previously published molecular phylogeny of Papilio butterflies that included 51 Papilio species representing all major species groups, and two outgroups: Pachliopta neptunus and Eurytides marcellus (Zakharov et al. These two species were traditionally classified as Batesian mimics of aposematic Danaus and Euploea, but were experimentally shown to be themselves chemically defended, at least under certain conditions. Potential erosion of rattling behaviour among nonvenomous snakes on islands lacking rattlesnakes. MIMICRY IN BUTTERFLIES: A SINGULAR ADAPTATION F ew adaptations in nature are as striking and widely appreciated as bright, diverse wing color patterns of butterflies. Dynamics of the evolution of Batesian mimicry: molecular phylogenetic analysis of ant‐mimicking Myrmarachne (Araneae: Salticidae) species and their ant models, Relationships between visual characteristics of rainforest butterflies and responses of a specialized insectivorous bird, Genetic constraints and the evolution of display trait sexual dimorphism by natural and sexual selection, Colour pattern specification in the mocker swallowtail, The evolution and distribution of species body size. The above analysis shows that character state path networks, combined with phylogenetic analysis, are a powerful set of tools to understand the organization of Batesian mimetic diversity. 2A). Genetic correlation between white and red spot sizes is also estimated similarly to the above, except for the correlation was that between grandmother red (white) spot and granddaughter white (red) spot. In all subsequent analyses we used general linear models assuming a normal distribution. Vane‐Wright also suggested that once mimicry evolves, sexually monomorphic mimicry and female‐limited mimicry could interconvert in response to changing selective pressures. In butterflies, there is a strong correlation between palatability and flight velocity, but there is only weak correlation between palatability and flight path. 1995; Mallet 2004; Kunte 2008). The nature of learning is weighted in favor of the mimics, for a predator that has a bad first experience with a model tends to avoid anything that looks like it for a long time, and does not re-sample soon to see whether the initial experience was a false … : A possible new mechanism for maintaining female‐limited polymorphism in Batesian mimicry, Population genetic structure and evolution of Batesian mimicry in This form of defence is widely known as Batesian mimicry. ISSN 2045-2322 (online). What is increasingly being understood is that mimicry groups cannot be simply split into distasteful "models" and Batesian or Mullerian "mimics". (2020). The butterfly genus Limenitis (Fabricius) (Lepidoptera: Nymphalidae) has long been a model for the study of Batesian mimicry and is an ideal system to employ phy-logenetic hypothesis testing. Heraclides has a few monomorphic nonmimetic species and a large number of female‐limited mimics. Thus, some of the mimetic females might have switched their model to P. aristolochiae. Ethology Am. Although Vane‐Wright did not specifically address this question, Batesian mimicry theory offers several reasons (Bates 1862; Wallace 1889; Fisher 1958; Edmunds 1974; Sheppard 1975; Turner 1978; Ruxton et al. Form dissimilis mainly mimics Tirumala limniace and T. septentrionis, whereas form clytia mimics Euploea species. The arrows show the years when P. aristolochiae established populations on each group. We first tested the fit of the white and red spot sizes to a normal distribution by the one-sample Kolmogorov–Smirnov test (in the ks.test package), separately testing the field-collected samples (temporal change analysis for the samples from Okinawa and other islands separately) and the laboratory-reared samples (heritability estimation). From this ambiguous phylogenetic tree, Prudic and Oliver concluded that nonmimetic arthemis was derived from mimetic astyanax and arizonensis, arthemis having reverted to the nonmimetic cryptic coloration in the absence of the model. In contrast, f. polytes (Fig. REVISING A CLASSIC BUTTERFLY MIMICRY SCENARIO: DEMONSTRATION OF MULLERIAN MIMICRY BETWEEN FLORIDA VICEROYS (LIMENITIS ARCHIPPUS FLORIDENSIS) AND QUEENS (DANA US GILIPPUS BERENICE) DAVID B. RITLAND Department of Zoology, University of Florida, Gainesville, Florida 32611 USA Abstract. Katoh, M., Tatsuta, H. & Tsuji, K. Rapid evolution of a Batesian mimicry trait in a butterfly responding to arrival of a new model. We hypothesized that because of the changed predation pressure due to the immigration of the white spot model, natural selection (directional and stabilizing selection) would have driven the wing colour patterns of f. polytes to more closely resemble the model from the former selectively neutral state in the absence of the model. The monarch and viceroy butterflies were believed to be exhibiting Batesian mimicry for a very long time; the monarch was thought to be the harmful one. 1H) if the hind-wing white spot of P. aristolochiae is ignored. A consensus tree constructed from the Bayesian analysis had topology and branch lengths matching the MP bootstrap consensus and ML trees. (A) A butterfly specimen from the University Museum, University of Tokyo. There are actually many instances all along this continuum between palatable/unpalatable and unpalatable/unpalatable pairings in which mimics … Furthermore, a comprehensive study based on three mitochondrial and seven nuclear regions sequenced from more specimens, and published almost concurrently, has shown that the nonmimetic arthemis is, in fact, basal (Mullen et al.

Second, the distribution of mimicry types is highly unequal: monomorphic mimicry (state path 2, n= 5) and female‐limited mimicry (state path 10, n= 8), have evolved repeatedly in Papilio whereas polymorphic mimicry (n= 1) and dimorphic mimicry (n= 2) have evolved rarely. Behav. This is because experimental evidence invariably shows the Papilio species tested so far to be palatable to predators and therefore Batesian mimics (Brower 1957, 1958; Codella and Lederhouse 1989; Chai 1990; Uesugi 1995). 3A with Fig. Extinct taxa are rarely represented on species phylogenies, thereby potentially biasing the conclusions of phylogenetic studies.
