(Phys.org) —Researchers from Oxford University in the U.K. have found evidence that suggests that cichlid fish evolved after the ancient Gondwana continent drifted apart, rather than before, as some have suggested. In their paper published in the journal Proceedings of the Royal Society B, the team describes how they compared found cichlid fossils with rocks known to have been a part of the Gondwana and also conducted DNA analysis to confirm that cichlid fish likely evolved approximately 65 to 57 million years ago—long after the continent came apart approximately 135 million years ago.
