<\/p>\n “It is extraordinary,” study co-author Emma Teeling<\/a>, a professor of molecular evolution and mammalian phylogenetics at University College Dublin, told Live Science in an email; “after decades of research and conflicting findings, we finally have uncovered how and when bats evolved.”<\/p>\n The analysis suggests that bats arose in Europe around 65 million years ago, contradicting previous hypotheses proposing Asian<\/a>, African<\/a> or North American<\/a> origins around 50 million years ago. Additionally, the researchers found that echolocation<\/a> and true flight evolved early in bats, roughly 50 million years ago, rather than multiple times after modern bats began to diversify.<\/p>\n “This study transforms bat evolution research because it finally gives us a robust, resolved family tree and biogeography, something that’s eluded scientists for decades,” study co-author Sonja Vernes<\/a>, a professor and head of the Neurogenetics of Vocal Communication Research Group at the University of St Andrews in the U.K., told Live Science in an email. “Get the tree right, and everything else about bat evolution starts to fall into place.”<\/p>\n You may like<\/p>\n The study included members of all 21 recognized bat families, as well as some of the most remarkable bat species known on Earth. For example, the dataset contained the bumblebee bat (Craseonycteris thonglongyai, also called the Kitti’s hog-nosed bat), which, at about 1 inch, or 2.5 centimeters, long, is thought to be the smallest mammal on Earth; and the Madagascar’s sucker-footed bat (Myzopoda aurita), which has suction cups on its wrists and ankles to help it cling to smooth surfaces.<\/p>\n The research team \u2014 which comprised 137 scientists affiliated with Bat1K<\/a>, an international project to map the genomes of all living bat species \u2014 used advanced DNA<\/a> sequencing and computational techniques to identify individual genes and redraw the bat family tree.<\/p>\n “The value we bring is in innovative methods and unparalleled data that together yield an evolutionary tree that includes all these key fossils,” study co-author Liliana D\u00e1valos<\/a>, a professor of phylogenetics and tropical deforestation at Stony Brook University in New York, told Live Science in an email.<\/p>\n Among other discoveries, the researchers found that a 50 million-year-old fossil from southern France of the extinct species Vielasia sigei, which shows signs of advanced echolocation<\/a>, sits within the oldest branch of the bat family tree, indicating that echolocation predates the diversification of modern bats. This finding, together with the result that true flight appeared early in bats, helps to explain why this lineage has been so successful and evolved into more than 1,500 species worldwide today, according to the study.<\/p>\n \n With a body length of about 1 inch, the bumblebee bat (Craseonycteris thonglongyai) is thought to be the smallest mammal on Earth. It occurs in western Thailand and southeast Myanmar.<\/p>\n (Image credit: Daniel Whitby)<\/p>\n After emerging in Europe, bats quickly dispersed into Africa, establishing a Europe-Africa hub from which they expanded into Asia, the Americas and Australia, the results suggest. Bats are the only mammals capable of true flight, meaning they flap their wings<\/a> and don’t simply glide or parachute. Throughout their evolution, they have acquired longer lifespans than other mammals of similar body size, surviving eight to 10 times longer than might be expected and showing few signs of aging and cancer, according to the study.<\/p>\n What to read next<\/p>\n “Some bat species live remarkably long lives for their size, and can shrug off diseases<\/a> that would make us seriously ill,” Vernes said. “Until now, we didn’t have a solid enough foundation to properly understand how bats evolved their most extraordinary traits, from flight and echolocation to their remarkable lifespans and resistance to disease. Now we do.”<\/p>\n The genomic resource built for the study lays the foundation for future research into bats’ longevity and disease resistance, with potential benefits for humans, Vernes said. “If we can understand how they do this at the genetic level, it could eventually help us design bat-inspired approaches to improve human health,” she said.<\/p>\n The findings could also aid bat conservation through genomic methods. Protecting bats is important because they help to maintain healthy ecosystems by pollinating plants, dispersing seeds and consuming huge numbers of insect pests, Vernes said. There is also more work to be done to identify the ancestor of all living bats, whose genome the researchers took a first stab reconstructing.<\/p>\n “For me, this isn’t the end of the story,” Vernes said; “it’s just the first chapter.”<\/p>\n Morales, A.
