Scientists say convergent evolution is much more common than previously thought. An evolutionary tree, or phylogenetic tree, is a branching diagram showing the evolutionary relationships among various biological species based upon similarities and differences in their characteristics. Historically, this was done using their physical characteristics — the similarities and differences in various species’ anatomies. However, advances in genetic technology now enable biologists to use genetic data to decipher evolutionary relationships. According to a new study, scientists are finding that the molecular data is leading to much different results, sometimes overturning centuries of scientific work in classifying species by physical traits. Molecular Data vs. Morphology-Based Trees New research led by scientists at the Milner Center for Evolution at the University of Bath suggests that determining evolutionary trees of organisms by comparing anatomy rather than gene sequences is misleading. The study, published in the journal Communications Biology on May 31, 2022, shows that we often need to overturn centuries of scholarly work that classified living things according to how they look. “It means that convergent evolution has been fooling us — even the cleverest evolutionary biologists and anatomists — for over 100 years!” Matthew Wills Since Darwin and his contemporaries in the 19th Century, biologists have been trying to reconstruct the “family trees” of animals by carefully examining differences in their anatomy and structure (morphology). However, with the development of rapid genetic sequencing techniques, biologists are now able to use genetic (molecular) data to help piece together evolutionary relationships for species very quickly and cheaply, often proving that organisms we once thought were closely related actually belong in completely different branches of the tree. Geographic Distribution and Molecular Data Alignment For the first time, scientists at Bath compared evolutionary trees based on morphology with those based on molecular data, and mapped them according to geographical location. They found that the animals grouped together by molecular trees lived more closely together geographically than the animals grouped using the morphological trees. Matthew Wills, Professor of Evolutionary Paleobiology at the Milner Center for Evolution at the University of Bath, said: “It turns out that we’ve got lots of our evolutionary trees wrong. “For over a hundred years, we’ve been classifying organisms according to how they look and are put together anatomically, but molecular data often tells us a rather different story. “Our study proves statistically that if you build an evolutionary tree of animals based on their molecular data, it often fits much better with their geographical distribution. “Where things live – their biogeography – is an important source of evolutionary evidence that was familiar to Darwin and his contemporaries. “For example, tiny elephant shrews, aardvarks, elephants, golden moles, and swimming manatees have all come from the same big branch of mammal evolution — despite the fact that they look completely different from one another (and live in very different ways). “Molecular trees have put them all together in a group called Afrotheria, so-called because they all come from the African continent, so the group matches the biogeography.” Molecular evolutionary trees show that elephant shrews are more closely related to elephants, than they are to shrews. Credit: Danny Ye Convergent Evolution’s Impact on Phylogenetic Analysis The study found that convergent evolution – when a characteristic evolves separately in two genetically unrelated groups of organisms – is much more common than biologists previously thought. Professor Wills said: “We already have lots of famous examples of convergent evolution, such as flight evolving separately in birds, bats, and insects, or complex camera eyes evolving separately in squid and humans. “But now with molecular data, we can see that convergent evolution happens all the time – things we thought were closely related often turn out to be far apart on the tree of life. “People who make a living as lookalikes aren’t usually related to the celebrity they’re impersonating, and individuals within a family don’t always look similar — it’s the same with evolutionary trees too. “It proves that evolution just keeps on re-inventing things, coming up with a similar solution each time the problem is encountered in a different branch of the evolutionary tree. “It means that convergent evolution has been fooling us — even the cleverest evolutionary biologists and anatomists — for over 100 years!” Biogeography as a Test for Evolutionary Trees Dr. Jack Oyston, Research Associate and first author of the paper, said: “The idea that biogeography can reflect evolutionary history was a large part of what prompted Darwin to develop his theory of evolution through natural selection, so it’s pretty surprising that it hadn’t really been considered directly as a way of testing the accuracy of evolutionary trees in this way before now. “What’s most exciting is that we find strong statistical proof of molecular trees fitting better not just in groups like Afrotheria, but across the tree of life in birds, reptiles, insects, and plants too. “It being such a widespread pattern makes it much more potentially useful as a general test of different evolutionary trees, but it also shows just how pervasive convergent evolution has been when it comes to misleading us.” Reference: “Molecular phylogenies map to biogeography better than morphological ones” by Jack W. Oyston, Mark Wilkinson, Marcello Ruta and Matthew A. Wills, 31 May 2022, Communications Biology. DOI: 10.1038/s42003-022-03482-x Protein condensates (shown here in a microscope image) are critical to the process of gene expression in cells, and condensate formation depends on proteins’ intrinsically disordered regions, a new study from researchers at Princeton, the Dana-Farber Cancer Institute and Washington University showed. Credit: Amy Strom, Princeton University Recent research shows that proteins’ intrinsically disordered regions (IDRs) are critical for chromatin regulation and gene expression. Mutations in these IDRs affect cellular functions, especially in the human cBAF complex. According to textbooks, proteins work by folding into stable 3D shapes that, like Lego blocks, precisely fit with other biomolecules. However, this depiction of proteins, the “workhorses of biology,” doesn’t tell the whole story. Around half of all proteins have stringy, unstructured bits hanging off them, dubbed intrinsically disordered regions, or IDRs. Because IDRs have more dynamic, “shape-shifting” geometries, biologists have generally thought that they cannot have as precise of a fit with other biomolecules as their folded counterparts, and as such, assumed these thread-like entities may contribute less significantly to overall protein function. Now, a multi-institutional collaboration has uncovered how a key aspect of cell biology is controlled by IDRs. Their study, recently published in the journal Cell, reveals that IDRs have specific and important interactions that play a central role in chromatin regulation and gene expression, essential processes across every living cell. The cBAF Complex: Unlocking DNA for Gene Expression The researchers focused on disordered regions of the human cBAF complex, a multi-component group of proteins in the nucleus that works to open up the densely coiled-up DNA inside cells called chromatin, enabling genes along DNA to be expressed and turned into proteins. Mutations in the IDRs of one family of cBAF subunits, ARID1A and ARID1B, which are highly frequent in cancer and neurodevelopmental disorders, throw chromatin remodeling and gene expression out of whack, suggesting IDRs are anything but trivial extras. In particular, the study revealed that the IDRs form little droplets called condensates that separate out from surrounding cellular fluid, just like drops of oil in water. The specific interactions that happen in these condensates allow proteins and other biomolecules to congregate in particular locations to carry out cellular activities. While scientists have shown that condensates perform a myriad of tasks, it was not known if these special liquid droplets had any role in chromatin remodeling, nor whether their specific amino acid sequences served specific functions. Researchers from Princeton, the Dana-Farber Cancer Institute, and Washington University in St. Louis teamed up to study the effects of different mutations in the ARID1A/B IDRs on the ability of the cBAF protein complex to form condensates and recruit partner proteins needed for gene expression. Some of the mutations examined in the study have been implicated in cancer or neurodevelopmental disorders. The results provide insights into how these mutations cause cellular processes to go awry and could form the basis for novel therapeutic strategies. A New Paradigm in Protein Biology “For the first time, we’ve shown that intrinsically disordered regions are fundamentally important for the operation of a key chromatin remodeling complex, the cBAF complex,” said Amy Strom, co-lead author of the study. “Our findings should be applicable to IDRs in general and could have significant implications for how cells do everything they do.” Strom is co-lead author along with Ajinkya Patil, a former doctoral student at Harvard Medical School. Strom is a postdoctoral researcher in the lab of co-senior author Clifford Brangwynne, Princeton’s June K. Wu ’92 Professor in Engineering and director of the Omenn-Darling Bioengineering Institute; and Patil worked in the lab of co-senior author Cigall Kadoch, associate professor of pediatric oncology at the Dana-Farber Cancer Institute and Harvard Medical School, whose lab has a long-standing interest in chromatin remodeling in human health and disease. “The degree to which even subtle disease-associated perturbations in IDR sequences altered the function of this major chromatin remodeler along the genome was surprising, and led us to explore the basis of the specific changes down to amino acid grammar,” said Patil. Brangwynne, whose lab has studied disordered sequences and their role in forming condensates for years, said: “Intrinsically disordered regions are everywhere in the vast catalog of human and other organisms’ proteins, and they’re playing central roles in physiology and disease in ways we’re just starting to understand.” “Our discoveries shine new light not only on the mechanisms of cBAF chromatin remodeling complexes, which are among top targets in oncology, but on the inherent nature of sequence specificity in to-date poorly understood IDR protein sequences,” said Kadoch. “These findings provide new foundations of important relevance toward the therapeutic targeting of condensates and their constituents.” Reference: “A disordered region controls cBAF activity via condensation and partner recruitment” by Ajinkya Patil, Amy R.

Researchers have made significant advancements in understanding cat evolution, uncovering the genetic reasons behind the stability and simplicity of cat genomes compared to other mammals. Their study highlights the importance of specific DNA regions in species differentiation and the variation in olfactory genes among cat species, providing valuable insights for conservation and scientific understanding of feline biology. Researchers at the Texas A&M School of Veterinary Medicine & Biomedical Sciences (VMBS), along with a multidisciplinary team of collaborators, have made significant discoveries regarding the evolutionary history of cats. Their findings reveal the developmental pathways through which various cat species, including lions, tigers, and domestic cats, have diverged. Furthermore, the research illuminates the connection between genetic variations in cats and vital survival skills, such as their heightened sense of smell for detecting prey. By comparing genomes of several cat species, the project, recently published in Nature Genetics, has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are most likely to evolve rapidly and how they play a role in species differentiation. “Our goal was to better understand how cats evolved and the genetic basis of the trait differences between cat species,” said Dr. Bill Murphy, a VMBS professor of veterinary integrative biosciences who specializes in cat evolution. “We wanted to take advantage of some new technologies that allow us to create more complete cat genomic maps. “Our findings will open doors for people studying feline diseases, behavior, and conservation,” he said. “They’ll be working with a more complete understanding of the genetic differences that make each type of cat unique.” Variations On A Theme Among the things the scientists were trying to better understand is why feline chromosomes — cellular structures containing the genetic information for traits like fur color, size, and sensory abilities — are more stable than in other mammal groups. “We’ve known for a while now that cat chromosomes across species are very similar to each other,” Murphy said. “For example, the chromosomes of lions and domestic cats hardly differ at all. There appear to be far fewer duplications, rearrangements, and other types of variation than what are commonly found in great apes.” In the primate order, this kind of genetic variation has led to the evolution of different species — including humans and great apes. “The great ape genomes tend to break and rearrange, and even human genomes have very unstable regions,” Murphy said. “These variations may predispose certain individuals to have genetic conditions, like autism and other neurological disorders.” The key to this variation between cats and apes, as Murphy found out, appears to be the frequency of something called segmental duplications — segments of DNA that are highly similar copies of other DNA segments found elsewhere in the genome.

Credit: Dr. William Murphy, Texas A&M University, and colleagues “Primate genome researchers have been able to link these segmental duplications to chromosome rearrangements,” he said. The more segmental duplications you have in your DNA, the more likely the chromosomes are to rearrange, etc. “What we discovered by comparing a large number of cat species genomes is that cats have just a fraction of the segmental duplications found in other mammal groups — primates actually have seven times more of these duplications than cats. That’s a big difference, and now we believe we understand why cat genomes are more stable,” he said. A Needle In A (Double) Helix While cats may not have as many large genetic rearrangements in their DNA, they still have plenty of differences. Through their research, Murphy and his colleagues now better understand which parts of cat DNA cause those variations, especially the variations that define speciation, or the differences between species. “It turns out that there’s a large region on the center of the X chromosome where most of the genetic rearrangements are happening,” Murphy said. “In fact, there’s one specific repetitive element within this region called DXZ4 that evidence tells us is largely responsible for the genetic isolation of at least two cat species, the domestic and jungle cat.” DXZ4 is what Murphy calls a satellite repeat — it’s not a typical gene that codes for a physical trait like fur color, but, rather, it aids in the three-dimensional structure of the X chromosome and likely played an important role in cat speciation. “We still don’t know the precise mechanism, but by comparing all these cat genomes, we can better measure the rate at which DXZ4 evolved in one species compared to all the others. What we learned is that DXZ4 is one of the most rapidly evolving parts of the cat genome; it’s evolving faster than 99.5% of the rest of the genome,” he explained. “Because of the rate at which it mutates, we were able to demonstrate why DXZ4 is probably linked to speciation,” Murphy said. Sniffing Out Elusive Genes Using new, highly detailed genome sequences, the team also uncovered clearer links between the number of olfactory genes, which govern scent detection in cats, and variation in social behavior and how they relate to their surroundings. “Since cats are predators who rely heavily on smell to detect their prey, their sense of smell is a pretty important part of who they are,” he said. “Cats are a very diverse family, and we’ve always wanted to understand how genetic variation plays a role in different cat species’ ability to smell in their different environments. “Lions and tigers have a pretty big difference between certain odorant genes involved in detecting pheromones, which are chemicals that different animals release into the environment to communicate information about identity, territory, or danger,” Murphy said. “We think the large difference has to do with lions being very social animals living in family groups and tigers living a solitary lifestyle. Lions may have a reduced reliance on pheromones and other odorants because they’re constantly around other lions, reflected in the fewer genes of this type in their genomes,” he said. Tigers, on the other hand, need to be able to smell prey across very large territories as well as find mates. “Tigers, in general, have large olfactory and pheromone receptor repertoires,” Murphy said. “We think this is directly tied to the size of their territories and the variety of environments in which they live.” Domestic cats, on the other hand, appear to have lost a wide range of olfactory genes. “If they don’t have to travel as far to find what they need because they’re living with people, it makes sense that natural selection wouldn’t preserve those genes,” he said. Murphy shared that his favorite example from the project is the odorant receptors from the fishing cat, an aquatically adapted wild cat species living in Southeast Asia. “We were able to show that fishing cats have retained many genes for detecting waterborne odorants, which is a pretty rare trait in terrestrial vertebrates,” he said. “All of the other cat species have lost these specific genes over time, but fishing cats still have them.” This new information about olfactory genes in cats was made possible through a new approach to genome sequencing called trio binning, which allows researchers to sequence the most difficult regions of a genome. This new technology also makes separating maternal and paternal DNA much easier. “With trio binning, you can now take DNA from an F1 hybrid — an animal whose DNA is split 50-50 between parents of different species — and cleanly separate the maternal and paternal DNA, giving you two complete sets of DNA, one for each parent species,” Murphy said. “The process is much simpler, and the results are more complete.” Filling In The Blanks One of the most important conclusions from the project is that cat species may be similar in many ways, but their differences matter. “These differences are showing us how these animals are perfectly suited for their natural environments,” Murphy said. “They’re not interchangeable, and that’s valuable information for conservationists and others working to preserve or restore species in their natural habitats. “For example, you can’t assume that tigers from Sumatra and Siberia are the same,” he said. “Their environments are wildly different, and those tiger populations have likely developed specialized genetic adaptations to help them survive in these very different places.” It’s also important for scientists to realize that the sections of genomes that are the most difficult to assemble may just be the key to understanding crucial bodily systems like immunity and reproduction. “Olfactory genes aren’t the only ones that have been challenging to sequence and study. Scientists have also struggled to sequence immune and reproductive genes, so previous studies are missing this kind of information. Imagine trying to study a genetic condition in cats, humans, or any species, for that matter, without having all the pieces; this is why assembling complete genomes matters,” Murphy said. For now, Murphy and his team will continue applying the most advanced genome sequencing and assembly technologies to cat genomes in order to fill in as much information as possible about the world of cats.
