Recursive language and modern imagination were acquired simultaneously 70,000 years ago

The lion-man sculpture from Germany (dated to 37,000 years ago) must have been first imagined by the artist by mentally synthesizing parts of the man and beast together and then executing the product of this mental creation in ivory. The composite artworks provide a direct evidence that by 37,000 years ago humans have acquired prefrontal […]

Genomic data reveal intense fish harvesting causes rapid evolution

Over recent decades, many commercially harvested fish have grown slower and matured earlier, which […]

why the textbook needs an update

The study challenges decades-old ideas about evolution, and why animals behave as they do. Co-author Professor Michael Jennions from The Australian National University (ANU) says it was […]

Fish reveal limb-regeneration secrets

In the current issue of Proceedings of the National Academy of Sciences, Michigan State University scientists show that gar, a toothy, freshwater fish, can reveal many evolutionary secrets — even possible genetic blueprints for limb regeneration in people.
