Bigger brains led to bigger bodies in our ancestors
New research suggests that humans became the large-brained, large-bodied animals we are today because of natural selection to increase brain size. The work contradicts previous models that treat brain size and body size as independent traits. Instead, the study shows … Continue reading
Penguin brains not changed by loss of flight
Losing the ability to fly gave ancient penguins their unique locomotion style. But leaving the sky behind didn’t cause major changes in their brain structure, researchers suggest after examining the skull of the oldest known penguin fossil. Paleontology News — … Continue reading
Ancient brains turn paleontology on its head
When scientists presented evidence of an ancient, fossilized brain a few years ago, it challenged the long-held notion that brains don’t fossilize. Now, seven new specimens have been unearthed, each showing traces of neural tissue from what was undoubtedly a … Continue reading
Ancient brains turn paleontology on its head
Science has long dictated that brains don’t fossilize, so when Nicholas Strausfeld co-authored the first ever report of a fossilized brain in a 2012 edition of Nature, it was met with “a lot of flack.” read more (e) Science News … Continue reading
Dinosaurs used nasal passages to keep brains cool
Dinosaur nasal passages were certainly nothing to sneeze at. Possessing among the largest and most complex nasal passages seen in animals, their function has puzzled paleontologists. New research suggests that the size and shape of these nasal passages would have … Continue reading
Dinosaurs used nasal passages to keep brains cool
“My work represents the first test of the hypothesis that the elaborated nasal passages of large dinosaurs functioned as efficient heat exchangers,” explained Jason Bourke, doctoral student researcher at Ohio University and lead author of the study. Using a branch … Continue reading
