Supernovae bombarded Earth with cosmic energy starting as many as 8 million years ago, with a peak some 2.6 million years ago, initiating an avalanche of electrons in the lower atmosphere and setting off a chain of events that feasibly ended with bipedal hominins.
New computational analysis finds that more than two dozen human zinc finger transcription factors, previously thought to control activity of similar genes across species have in fact human-specific roles and could help explain how our species came to be.

Little Foot skull/University of the Witwatersrand (2014)If you read the science news, you’ve probably been hearing about Little Foot alot:The first of a raft of papers about ‘Little Foot’ suggests that the fossil is a female who showed some of the earliest signs of human-like bipedal walking ar
