New research suggests that some birds evolved over time to have smaller bodies and maintain the large brains of their ancestors. And the biggest evolutionary event happened after the dinosaurs went extinct.
That's because new research suggests that some birds evolved over time to have smaller bodies and maintain large brains.Researchers studied the endocasts of skulls belonging to hundreds of dinosaurs and extinct birds. They used CT scans of the animals' ancient skulls to create endocasts, which act like an imprint of the brain in the skull, reflecting brain sizes . Then, they compared the brain sizes with brain measurements of modern birds in a large data set.
Before the mass extinction event, the similarities between dinosaur and bird brains were almost indistinguishable."There is no clear line between the brains of advanced dinosaurs and primitive birds," said Amy Balanoff, study co-author and assistant research professor in Johns Hopkins University's Department of Psychological and Brain Sciences, in a statement.
