Why are there so many lizards in Australia? The ancient climate holds a clue

The Conversation · · 616 words · By Janne Torkkola
Evolutionary Biology Biodiversity climate_change

The author describes a new evolutionary tree of the Sphenomorphini lizard group in Australia, suggesting that climatic changes during the Early Miocene drove species diversification. The article concludes by contrasting the slow pace of prehistoric climate change with the potential catastrophic impact of rapid modern warming.
