Evolutionary biologists show that the color variants of female cuckoos are based on ancient mutations
Every cuckoo is an adopted child—raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of ...

A key gene helps explain how the ability to glide has emerged over-and-over during marsupial evolution
People say "When pigs fly" to describe the impossible. But even if most mammals are landlubbers, the ability to glide or fly has evolved again and again during mammalian evolution, in species ranging from bats to flying squirrels. ...
