The National Science Foundation has released news on a study that helps explain limb loss in whales.
“Hans Thewissen and his colleagues report that ancient whales–four-footed land animals not unlike large modern dogs–evolved into graceful, streamlined swimmers through a series of small genetic changes during the whales’ embryonic development.”
See Carl Zimmer at The Loom for a recent update on The Path Toward Leviathan and his earlier “whale chronicles“.
