Climate change steered early vertebrate evolution

The collapse of rain forests and a dryer climate 307 million years ago led to extinction of many early amphibians, but presented new opportunities for other early vertebrates. These early vertebrates were egg-laying animals and depended therefore less on water than amphibians. Climate changes are thus important for the evolution of vertebrates, leading to the extinction of some species, but favouring the development of others such as our early vertebrate ancestors.
