<NYU Grossman School of Medicine suggests that a genetic change in our ancient ancestors could partially explain why humans don’t have tails, unlike monkeys.
Recently published in the journal Nature, the work compared the DNA of tail-less apes and humans to that of tailed monkeys and found an insertion of DNA shared by apes and humans, but missing in monkeys. When the research team engineered a series of mice to examine whether the insertion, in a gene called TBXT, affected their tails, they found a variety of tail effects, including some mice born without tails.>>
