The scars of this chromosomal crisis are seen in cases from across all the common cancer types, accounting for at least one in forty of all cancers. The phenomenon is particularly common in bone ...

Mammal species diversified more rapidly early in their history – peaking roughly 66 million years ago – before a long-term decline in diversification punctuated by diminishing bursts of evolutionary ...

This has allowed them to map the evolutionary history of eukaryotic genes in unprecedented detail - giving insight into the mechanisms of evolution in the very earliest forms of life. Their paper, ...
