The average adult human brain weighs about 3 pounds or 1.4 kilograms. It is roughly the size of two clenched fists put together and fills the cranial cavity.
The average Neanderthal brain size was about 1,600 cc, which is slightly larger than the average modern human brain size of around 1,400 cc. This suggests that Neanderthals had relatively large brains compared to their body size.
Lucy's brain was approximately one-third the size of a modern human brain.
The Homo habilis species had brains that were roughly half the size of modern brains when they first appeared around 2.5 million years ago. Over time, their brains gradually increased in size until they were just slightly smaller than modern human brains. This evolutionary development in brain size is thought to be a key factor in the cognitive advances that led to the emergence of the human species.
A Neanderthal's brain typically had a volume of around 1300-1750 cubic centimeters, which is roughly equivalent to 79-107 cubic inches.
Neanderthals had slightly larger brains than modern humans on average, but there were differences in the organization and structure of their brains. Neanderthals had a larger visual processing area, while modern humans have larger areas related to higher cognitive functions. Neanderthals likely had similar cognitive abilities to modern humans, but may have had differences in social behaviors and communication.

The same as a modern human.
Lucy's brain was approximately one-third the size of a modern human brain.
The Neanderthal brain was the same size as modern human.
About 3/4ths of a modern human.
it's roughly twice the size of the human brain.
The average size of a donkey's brain is comparable to a human. The donkey's brain is between 50 and 75 percent of the size of the human brain.
the size of a human fist
