David M. Hillis

David M. Hillis is an American evolutionary biologist and geneticist known for his research on the tree of life, studying how different species are related through their genetic and evolutionary history. He has contributed to understanding biodiversity, conservation, and the evolutionary relationships among animals, especially amphibians and reptiles. Hillis has also been involved in developing methods to analyze large amounts of genetic data, helping scientists better reconstruct evolutionary trees. His work helps us understand the origins and connections of various species, informing conservation efforts and our knowledge of Earth's biological history.
