Climate change that occurred 307 million years ago caused some species to perish and others to thrive, according to a new study.
The research, from the University of Birmingham, suggests some species of tetrapods – vertebrates that have four feet – were greatly affected by the onset of a less humid climate millions of years ago.
The change resulted in mass extinctions, but it caused some groups, among them the species that gave rise to modern mammals, to thrive and expand across the world, according to the new study.
