00:04In nature, generally the larger the brain, the smarter the creature.
00:07Well now, new research suggests that the brains of domestic dogs are getting larger.
00:12But scientists are sort of baffled as to why.
00:14Domestication has long been a mechanism for smaller brains in animals, and sort of humans as well.
00:19Over the last three millennia, anthropologists say human brains have shrunk in volume.
00:23And compared to wolves, dog-relative brain size is smaller as well.
00:26But now a new study published in the journal Evolution outlines how the more different the dog breed is from
00:31a wolf now, the larger the brain.
00:33Experts believe that when dogs were first domesticated, their brains shrunk as they no longer needed as much bandwidth as
00:38they could rely on their human best friends.
00:40But now, as breeding has caused forced evolution over the last several thousand years, their cognitive abilities are likely getting
00:46better.
00:47Meaning their brains are growing, with evolutionary biologist Nicholas Colm saying about the findings,
00:51Different dog breeds live in varying levels of social complexity and perform complex tasks, which likely require a larger brain
00:58capacity.
00:59Though the researchers found that the only correlation of brain growth was how dissimilar the breeds were to wolves, rather
01:05than their actual cognitive abilities.
