WebThe mass extinction at the end of the Cretaceous period, 65 million years ago, wiped out the dinosaurs along with every other land animal that weighed much more than 25 kg. This cleared the way for the expansion of the mammals on land. In the sea at this time, the fish again became the dominant vertebrate taxon. WebThis gene was FOXP2. After sequencing the FOXP2 gene in the family they found a specific mutation in the gene that was shared by all the affected family members. This confirmed the importance of FOXP2 in human language.
