For want of mums woolly mammoths were lost.

A genetic analysis of ancient permafrost suggests that after the last Ice Age the Arctic shifted from a landscape dominated by nutritious flowering plants known as forbs to one dominated by hard-to-digest grasses and woody plants. Evolutionary geneticist Eske Willerslev of the University of Copenhagen and his colleagues report the finding in the Feb. 6 Nature. That shift may have helped drive the extinction of large herbivores such as woolly mammoths...
