We, as humans, have actually developed a sense of social responsibility. We have gone beyond our basic instincts. We can and we do. This is what sets us apart from the chimps. They are extremely brutal and hostile. Your next door neighbor is to be killed unless she is a juicy young female, who hasn't yet had her first baby, in which case you want her.

Some humans are mathematicians-others aren't.

Of course animals have a personality and emotions.

Mainly because as women's education increases all around the planet, we find that family size tends to drop.

If we start with chimpanzees, they differ from us with the composition of the DNA by only just over one percent. So, as far as genetics go, we're almost identical. The composition of the blood, the immune system, the structure of the brain - almost identical.

I wasn't trying to be a scientist. I only ever wanted to be a naturalist, like a David Attenborough.

You're thinking about putting scientists into small cages and doing research on them. I wish it could happen sometimes.
