Do apes have a brain the size of an human?

No, apes do not have brains the size of humans. While some apes have larger brains than other animals, human brains are significantly larger than those of any ape species.

Here's a breakdown:

* Human brain size: 1,350 cubic centimeters (cc) on average

* Gorilla brain size: 450 cc on average

* Chimpanzee brain size: 370 cc on average

* Orangutan brain size: 390 cc on average

While size isn't the only factor determining intelligence, humans have a much larger brain volume compared to apes. This allows for more complex cognitive abilities, including language, abstract thinking, and problem-solving.
