The size of an ant
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.
no they are extremly smart but their brains are about the size of a peanut
the word 'small' is qualitative and therefore can not be answered effectively. Birds in general do have small brains.
yes ostrich have bigger brain then his eyes
NO.... of course not

Yes.
Tests have not been conducted on the level of a kiwi's intelligence. However, for many years it was thought that the kiwi was not particularly smart. Scientists have revised that theory, with the recent discovery that kiwi brains were similar in size to the brains of "smarter" flying birds. To read more about the discovery regarding a kiwi's brain size, see the related link below.
Because fishes have small brains.
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.
