What animal has 32 brains?
Leech has 32 brains. A leech’s internal structure is segregated into 32 separate segments, and each of these segments has its own brain. Leech is an annelid.
Does brain size affect intelligence?
Overall, larger brain size and volume is associated with better cognitive functioning and higher intelligence. The specific regions that show the most robust correlation between volume and intelligence are the frontal, temporal and parietal lobes of the brain.
What animal is the smartest?
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community.

Which animal has most brains?
Fun Facts. The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms). Larger brains don’t necessarily make a smarter mammal. But as mammals evolved, many groups, from Primates to Carnivora, have shown independent increases in brain size.
Why do humans have large brains?
Brain size increased rapidly during human evolution due to the expansion of many brain regions, resulting in human brains being exceptionally larger than those of our closest relatives. Humans have much larger brains than other primates, but it is not clear exactly when and how this difference emerged during evolution.
Do bigger dogs have bigger brains?
A new study published in Animal Cognition indicates that bigger dogs, who have larger brains than smaller dogs, perform better than smaller dogs on some measures of intelligence. … They used data from more than 7,000 purebred domestic dogs from 74 different breeds. Brain size was estimated based on breed standards.
Why did the human brain increase in size?
Over the last million years of evolution, our brain underwent a considerable increase in size and complexity, resulting in the exceptional cognitive abilities of the human species. This brain enlargement is largely due to an increase in the number of neurons in the cerebral cortex, the outer part of the brain.
