Ian Barnes (biologist)
Ian Barnes is an evolutionary geneticist notable for his work on ancient DNA, human and animal migration, and phylogenetics. Barnes is a Research Leader in the Department of Earth Sciences at the Natural History Museum in London.
He pioneered the use of ancient DNA to study the Late Pleistocene mammal fauna, which has provided insights into how animals responded to global climate change. More recently, his research has explored human population change in prehistoric Britain, including work on the Mesolithic human skeleton known as Cheddar Man
His work on phylogenetics includes a study of South American mammal species first identified by Darwin, led in collaboration with the University of York, and the American Museum of Natural History, which “resolved one of the last unresolved major problems in mammalian evolution: the origins of the South American native ungulates". He has also resolved the phylogenetic placement of the Nesophontidae, and evolutionary origins of various Caribbean mammal lineages including primates and rodents.
