The Tarsier

Okay, so I reckon evolution was VERY drunk when this little creature with HUGE eyes first walked on our planet. Unsurprisingly, they're not the most common of creatures- in fact, they're more or less, only found on the islands in Southeast Asia. Because they're not very common we don't actually know a lot about them, we don't really know why they have SUCH big eyes! The only real explanation scientists can come up with is that its down to a mutation in their DNA, which codes for their eyes. One of the other problems facing scientists is that this small primate is incredibly shy around humans, which of course provides quite a big problem for scientists! They're also incredibly athletic, with an unusually long anklebone enabling it to jump distances more than 40 times its own body length.

What makes human and chimp brains different?

The average weight of a chimpanzee brain is 384 grams (13.5 ounces), but human brains are around 3 and a half times heavier. Although each species has a differently structured brain, for example the brain cells in a rodent are much less efficiently packed so would therefore mean that  Rodents would  need a brain at least 35 times bigger than ours to have the same number of brain cells as an average human.

Chimps on the other hand are closely related to humans, so we share a very similar brain structure to them, however they still have around 3 and a half times less brain cells than a human - roughly 49 billion.

Chimpanzees have a lot less brain dedicated to white matter in the temporal cortex which means they have lot fewer connections in the brain (neural connections) so then they have a lesser ability to process information to the same level that humans can.
