ne of the few differences between humans and chimps comes from the amount of cell division for brain cells

human behaviors stand out by reaching levels of complexity unseen in any other part of the animal world, according to a neurobiologist

What makes humans special comes in no small part from the sheer quantity of available brain power – at least 300,000 brain cells for each neuron in a fruit fly brain.

Assume that there were salamanders living in some grasslands. Suppose, Lamarck argued, that these salamanders had a hard time walking because their short legs couldn't trample the tall grasses or reach the ground. Suppose that these salamanders began to slither on their bellies to move from place to place. Because they didn't use their legs, the leg muscles wasted away from disuse and the legs thus became small.

Spatial cognition

The ability to properly navigate and search through the environment is a critical task for many animals.

Research in 2007 shows that chimpanzees in the Fongoli savannah sharpen sticks to use as spears when hunting, considered the first evidence of systematic use of weapons in a species other than humans.

Language

The modeling of human language in animals is known as animal language research.

Consciousness

The sense in which animals can be said to have consciousness or a self-concept has been hotly debated; it is often referred to as the debate over animal minds.

It has been suggested that metacognition in some animals provides some evidence for cognitive self-awareness.[11] The great apes, dolphins, and rhesus monkeys have demonstrated the ability to monitor their own mental states and use an "I don't know" response to avoid answering difficult questions. These species might also be aware of the strength of their memories.
