A 'smoking gun' on the Ice Age megafauna extinctions
Date:2/5/2014

d to be the main stimulus promoting global scientific output, this study clearly demonstrates that extensive collaboration is a viable alternative.

'Smoking gun'

The article in Nature elaborates on the Willerslev group's results from 2011 where the researchers pointed at climate as the culprit for the mass extinction of some of the large mammals'. But in 2011 the researchers lacked a 'smoking gun'. Now they got it! 242 permafrost sediment samples and eight fossil samples from large mammals from around the Arctic have been dated and analysed for DNA. The data shows that the likely main reason for the mass extinction of the large mammals after the latest Ice Age is changes in the vegetation.
