Phys.org / Flightless ancestor shows brain evolution in pterosaurs and birds took different paths

Flight is a rare skill in the animal world. Among vertebrates, it evolved only three times: in bats, birds, and the long-extinct pterosaurs. Pterosaurs were the pioneers, taking to the skies more than 220 million years ago, ...
