These articles explore evolution - the changes seen in the inherited traits of a population from one generation to the next. Evolution is one of the great mysteries of biology, since it is a slow process and difficult to study.

In recent years, three mummified cubs from an extinct lion species have emerged from the Russian permafrost. Cloning might be possible, but is it wise?

Humans Didn't Outsmart Neanderthals, We Just Outlasted Them

New research suggests Neanderthals went extinct, not because we outcompeted them, but because we took over their ecological niche.
