An international team of scientists has uncovered new evidence linking early animal evolution to extreme climate change.

A dramatic rise in atmospheric oxygen levels has long been speculated as the trigger for early animal evolution, but direct evidence has proven elusive to scientists. In the Sept. 27 issue of the journal Nature, a UNLV-led research team for the first time offers evidence of a causal link between trends in early biological diversity and shifts in Earth system processes.
