New evidence helps solve how earliest birds took flight

The first bird to inhabit Earth used its robust hind legs to make two or three powerful leaps while flapping its way to flight, according to a study by the University of Southampton published in Developmental Biology.

Early snakes explored life underground, on land and at sea

Snakes are highly modified lizards, with more than 4,000 living species today. The origin of snakes has long been one of evolutionary biology's most debated questions. Their sparse fossil record has made it hard to pin down ...
