no they don't. there brain is as big as ours:)
Yes
"How are different parts of the human brain similar to and different from the brains of other primates?"
No. A monkey does not have two brains, only one as in apes and primates. No extant mammal has two true brains.
Yes, unless by 'primates' you actually mean something that isn't a primate. Primates care for their young, give milk, have advanced brains and sensory organs, and have hair so yes they are mammals, as are humans.
the word 'small' is qualitative and therefore can not be answered effectively. Birds in general do have small brains.
Humans and gorillas belong to the order of mammals called Primates. Primates are characterized by features such as forward-facing eyes, grasping hands and feet, and relatively large brains compared to body size.
All things are relative. Compared to an earthworm, turtles have big brains. Compared to a dog, turtles have small brains.
they differ by: 1) being much smaller, 2) having much smaller brains, 3) some higher primates also walked on 2 legs they normally walk on two. 4)lemurs and tarsiers are in the prosimians group and higher primates are in the anthropoids group.
Not necessarily. While some chordates, like humans and other mammals, have relatively large brains compared to their body size, not all chordates have large brains. Chordates range in complexity from simple organisms like tunicates to more advanced vertebrates like birds and primates.
They have a brain the size that is proportional to their small bodies.
Primates are characterised by large brains relative to other mammals. Their eyes face forward, giving them stereoscopic vision and vision is the sense they rely on most rather than smell like other mammals. Most primates with a few exceptions have opposable thumbs and have developed adaptations to climb trees. Primate babies take a long time to mature because of their brain size, relative to non-primates. Non-human primates have oestrus cycles and many species display swellings during their fertile period.
Early hominids were bipedal primates that lived around 6-7 million years ago. They had small brains, walked on two legs, and used simple tools. Over time, they evolved into various species, including Australopithecus and eventually Homo sapiens.
