Credit: Jon Suh By lassoing lizards, putting tiny chips on their legs, and tracking them for three years, Georgia Tech’s James Stroud revealed why species often appear unchanged for millions of years despite Charles Darwin’s theory of constant evolution. Charles Darwin said that evolution was constantly happening, causing animals to adapt for survival. But many of his contemporaries disagreed. If evolution is always causing things to change, they asked, then how is it that two fossils from the same species, found in the same location, can look identical despite being 50 million years apart in age? Everything changed in the past 40 years, when an explosion of evolutionary studies proved that evolution can and does occur rapidly — even from one generation to the next. Evolutionary biologists were thrilled, but the findings reinforced the same paradox: If evolution can happen so fast, then why do most species on Earth continue to appear the same for many millions of years? A green anole lizard (Anolis carolinensis). Credit: Day’s Edge Prods This is known as the paradox of stasis, and James Stroud, assistant professor in the School of Biological Sciences at the Georgia Institute of Technology, set out to investigate it. He conducted a long-term study in a community of lizards, measuring how evolution unfolds in the wild across multiple species. In doing so, he may have found the answer to one of evolution’s greatest challenges. His research was published as the cover story in the Proceedings of the Natural Academy of Sciences. Unraveling the Paradox “We call this a paradox because it doesn’t seem to make any sense,” Stroud said. “The most common explanation is that natural selection is working to stabilize a species’ appearance, with the assumption that an average form will help them survive the best. The problem is, when people do field studies, they almost never find that this kind of ‘stabilizing’ selection actually exists.” James Stroud uses a tiny lasso attached to a fishing pole to catch a lizard. Credit: Day’s Edge Prods Lassoing Lizards for Insight Stroud set up a field study with four different species of Anolis lizards (anoles) on a small island at the Fairchild Tropical Botanic Gardens in Coral Gables, Florida. He measured natural selection in all four lizard species over five consecutive time periods by catching and monitoring the survival of every lizard on the island. Stroud and his colleagues searched day and night for lizards. Using long fishing poles with tiny lassos at their tips, they gently captured them by their strong necks, placed them in coolers, and documented the exact branch or stump where they found each lizard.

Credit: Day’s Edge Prod Back in the lab, Stroud measured the lizards’ heads, legs, feet, weight, and even the stickiness of their toes. After assigning an identifying number to each lizard and marking them with a tiny tag under the skin, the team released the lizards to the same branches where they’d found them. They went out in the following days and weeks to catch the rest of them. Every six months for three years, Stroud and his team started the process over again. Catching the same lizards, taking measurements, releasing them, and making notes of which lizards survived and which didn’t. A Picture of Evolution Is Worth a Thousand Lizards By incorporating data for each time period, Stroud captured the history of every lizard in the community. He then related survival data to the variation in body traits, which allowed him to analyze which body traits were important predictors of survival. Taken together, the analysis painted a picture of how natural selection operated on the community as a whole. To his surprise, Stroud found that the stabilizing form of natural selection — that which maintains a species’ same, average features — was extremely rare. In fact, natural selection varied massively through time. Some years, lizards with longer legs would survive better, and other years, lizards with shorter legs fared better. For other times, there was no clear pattern at all. Researchers identified the lizards by harmless blacklight tags that they implanted under the skin of their legs. Credit: Day’s Edge Prods “The most fascinating result is that natural selection was extremely variable through time,” Stroud said. “We often saw that selection would completely flip in direction from one year to the next. When combined into a long-term pattern, however, all this variation effectively canceled itself out: Species remained remarkably similar across the entire time period.” Breaking New Ground The findings provided by Stroud’s study had never been seen before. There had never been such insight into how selection works on a community level, and certainly not at this level of detail. The reason scientists never understood how evolution works on the community level is because long-term studies like Stroud’s are extremely rare. Researchers are unlikely to undertake such projects because of the great amount of work and time required. “Evolution can and does happen — it’s this ongoing process, but it doesn’t necessarily mean things are constantly changing in the long run,” Stroud said. “Now we know that even if animals appear to be staying the same, evolution is still happening.” According to Stroud, understanding evolution is critical to everything that we want to understand about life on Earth. “Understanding evolution doesn’t only help us understand the plants and animals around us and how they’re distributed across the world,” he said. “It also shows us how life sustains itself in a world dominated by humans.” There have been very few studies that monitor how evolution unfolds in the wild at long time scales. That, according to Stroud, is why we have a biased view of what evolution is. “For a very long time, evolutionary biologists have tried to figure out what was behind this paradox of stasis idea,” Stroud said. “What this study shows is that the answer may not be particularly complicated — we just had to conduct a study in the wild for a long enough time to figure it out.” Reference: “Fluctuating selection maintains distinct species phenotypes in an ecological community in the wild” by James T.

UC Davis graduate student Jeffrey Groh has discovered how walnut trees are able to produce flowers of different sexes at different times in the same season. The genetic mechanism is similar to sex determination in many animals. Pictured, Groh with a California black walnut tree on the UC Davis campus. Credit: Sasha Bakhter, College of Biological Sciences Biologists at UC Davis have uncovered a fascinating genetic mechanism in walnut trees, allowing them to alternate between male and female flowers each season—a trait stable for 40 million years. This discovery not only sheds light on plant reproduction but also parallels mechanisms in human sex determination. Unraveling the Sexuality of Walnut Trees Biologists at the University of California, Davis, have uncovered the genetic basis behind the alternating sexes of walnut trees. Their research, published on January 3 in Science, identifies a mechanism that has remained stable in walnuts and their ancestors for an astonishing 40 million years. Intriguingly, this mechanism shares some similarities with sex-determination systems found in humans and other animals. Flowering plants employ various strategies to avoid self-pollination. Some have physical structures that make self-pollination difficult, while others produce distinct “male” and “female” plants. Certain species, like walnut, hickory, and pecan trees, take a more dynamic approach by alternating male and female flowers within the same season. Remarkably, each walnut tree consistently follows one of two patterns: it either begins the season with male flowers (“male-first”) or with female flowers (“female-first”). This phenomenon was first noted by Charles Darwin in 1877. In the 1980s, Scott Gleeson, a graduate student at UC Davis, discovered that this flowering pattern is controlled by a single genetic locus. Discovery of a Long-Standing Genetic Mechanism “Walnuts and pecans have a temporal dimorphism where they alternate male and female flowering through the season,” said Jeff Groh, graduate student in population biology at UC Davis and first author on the paper. “It’s been known since the 1800s but hasn’t been understood at the molecular level before.” This occurs in both domesticated walnuts and wild relatives, like Northern California black walnut. In wild species, the ratio of male-first to female-first trees is almost 1:1. Groh and his doctoral advisor, Professor Graham Coop of the Department of Evolution and Ecology, made use of data from UC Davis’ walnut breeding program and also tracked flowering in native Northern California black walnut trees growing around the UC Davis campus. Assigning them to male-first or female-first groups, the researchers sequenced their genomes and identified sequences associated with the trait. Evolutionary Insights: Mechanism Stability In walnuts, they found two variants of a gene linked to female-first or male-first flowering. This DNA polymorphism appears in at least nine species of walnut and has been stable for almost 40 million years. “It’s pretty atypical to maintain variation over such a long time,” Groh said. In this case, the two flowering types balance each other. If one flowering type becomes more common in the population than the other, the less common type gains a mating advantage, so it becomes more common. This pushes the system to a 50:50 equilibrium and maintains genetic variation. Pecans, Groh found, also have a balanced genetic polymorphism determining flowering order, but in a different part of the genome to walnut. The pecan polymorphism appears to be older than in walnut, at over 50 million years. How did walnuts and pecans, which are related, arrive at the same flowering mechanism through quite different genes? It could be that the ancestors of walnuts and pecans converged on similar solutions as they evolved. But it’s also possible that this time-separated flowering system appeared even longer ago in this family, about 70 million years ago, but over time the exact genetic mechanisms to achieve it have changed. Parallels to Animal Sex Determination Intriguingly, this is similar to the way animal sex chromosomes work, with two structural variants (X and Y chromosomes in humans and other mammals) kept roughly in balance. “There’s a clear parallel to a common mode of sex determination,” Groh said.

Credit: Germán Orizaola/Pablo Burraco, CC BY The largest release of radioactive material into the environment in human history occurred in 1986, with an accident on April 26 at reactor four of the Chornobyl Nuclear Power Plant. Severe impacts on the environment and the human population resulted from the acute exposure to high doses of radiation. But more than three decades after the accident, Chornobyl has become one of the largest nature reserves in Europe. Today, a diverse range of endangered species finds refuge there, including bears, wolves, and lynxes. The Chornobyl disaster is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear disaster in Japan.

Credit: Germán Orizaola Radiation can damage the genetic material of living organisms and generate undesirable mutations. However, one of the most interesting research topics in Chornobyl is trying to detect if some species are actually adapting to live with radiation. As with other pollutants, radiation could be a very strong selective factor, favoring organisms with mechanisms that increase their survival in areas contaminated with radioactive substances. Ironically, the Chornobyl accident occurred during a safety test. The resulting meltdown and explosions ruptured the reactor core and destroyed the reactor building. This was immediately followed by an open-air reactor core fire which lasted until May 4, 1986. Contaminated area within the Chornobyl Exclusion Zone (Ukraine). Credit: ArcticCynda Melanin Protection Against Radiation Our work in Chornobyl began in 2016. That year, close to the damaged nuclear reactor, we detected several Eastern tree frogs (Hyla orientalis) with an unusual black tint. The species normally has a bright green dorsal coloration, although occasional darker individuals can be found. Melanin is responsible for the dark color of many organisms. What is less known is that this class of pigments can also reduce the negative effects of ultraviolet radiation. And its protective role can extend to ionizing radiation too, as it has been shown with fungi. Melanin absorbs and dissipates part of the radiation energy. In addition, it can scavenge and neutralize ionized molecules inside the cell, such as reactive oxygen species. These actions make it less likely that individuals exposed to radiation will go on to suffer cell damage and increase their survival chances.

Credit: Germán Orizaola The Color of Chornobyl Tree Frogs After detecting the first black frogs in 2016, we decided to study the role of melanin coloration in Chornobyl wildlife. Between 2017 and 2019 we examined in detail the coloration of Eastern tree frogs in different areas of northern Ukraine. During those three years, we analyzed the dorsal skin coloration of more than 200 male frogs captured in 12 different breeding ponds. These localities were distributed along a wide gradient of radioactive contamination. They included some of the most radioactive areas on the planet, but also four sites outside the Chornobyl Exclusion Zone and with background radiation levels used as controls. Our work reveals that Chornobyl tree frogs have a much darker coloration than frogs captured in control areas outside the zone. As we found out in 2016, some are pitch-black. This coloration is not related to the levels of radiation that frogs experience today and that we can measure in all individuals. The dark coloration is typical of frogs from within or near the most contaminated areas at the time of the accident.

Credit: Germán Orizaola/Pablo Burraco, CC BY-SA Evolutionary Responses in Chornobyl The results of our study suggest that Chornobyl frogs could have undergone a process of rapid evolution in response to radiation. In this scenario, those frogs with darker coloration at the time of the accident, which normally represent a minority in their populations, would have been favored by the protective action of melanin. The dark frogs would have survived the radiation better and reproduced more successfully. More than ten generations of frogs have passed since the accident and a classic, although very fast, process of natural selection may explain why these dark frogs are now the dominant type for the species within the Chornobyl Exclusion Zone. Glyboke Lake, Chornobyl Exclusion Zone (Ukraine), 2019. Credit: Germán Orizaola The study of the Chornobyl black frogs constitutes a first step to better understanding the protective role of melanin in environments affected by radioactive contamination. In addition, it opens the doors to promising applications in fields as diverse as nuclear waste management and space exploration. We hope the current war in Ukraine will end soon and the international scientific community will be able to return to study, together with our Ukrainian colleagues, the fascinating evolutionary and rewilding processes of Chornobyl ecosystems.
