Neanderthals developed their own tools

Neanderthals were keen on innovation and technology and developed tools all on their own, scientists say. 

A new study challenges the view that our close relatives could advance only through contact with Homo sapiens

The team says climate change was partly responsible for forcing Neanderthals to innovate in order to survive. 

The research is set to appear in the Journal of Archaeological Method and Theory in December. 

“Basically, I am rehabilitating Neanderthals,” said Julien Riel-Salvatore, assistant professor of anthropology at the University of Colorado in Denver, who led the seven-year study. 

“They were far more resourceful than we have given them credit for.” 

Climate Change Affecting Bird Size

Via BBC, North American birds are shrinking.

Songbirds in the US are getting smaller, and climate change is suspected as the cause.

A study of almost half a million birds, belonging to over 100 species, shows that many are gradually becoming lighter and growing shorter wings.

This shrinkage has occurred within just half a century, with the birds thought to be evolving into a smaller size in response to warmer temperatures.

However, there is little evidence that the change is harmful to the birds.
