Woolly mammoth demise 'not linked to humans'

Woolly mammoths died out because of dwindling grasslands rather than hunting by humans, according to new research.
The findings from Durham University suggest that climate change was to blame, replacing the mammoths' grassland diet with trees.
The woolly mammoth was once commonplace across many parts of Europe and finally died out approximately 4,000 years ago.
