From Colin Barras at New Scientist:
The evolutionary story we have written to explain our ancestors’ move from sea to land may need a rethink. A fossil fish from this era has been discovered with several of the features of land animals – yet it was only distantly related to them.
Roughly 360 million years ago, one group of lobe-finned fish began evolving into four-legged, land-living animals that resulted in reptiles, amphibians and mammals like us.
However, a fossil discovered in a quarry in Ningxia, north China, now threatens that stability.More.
Yeah. Real history is a bitch. Just a bitch.
