I was discussing evolution with one of my friends when he asked me the following question: Why evolution didn't produce species with sophisticated brain (similar or more intelligent) such as human kind ? human beings are the only species that have a very sophisticated brain is it a coincidence ?
It's not coincidence that the species with the most sophisticated brain is the one most likely to be discussing its brain, as we are now! It's worth pointing out that there are other animals that could be regarded as being fairly close to us in terms of brain sophistication. We're not as special as we often like to think. Some intelligent mammals are more comparable to us than they are to, for example, lizards.
Evolution could certainly produce other animals with intelligence of our level or above. It hasn't yet, but it hadn't produced us a few hundred thousand years ago, either.
Dolphins have larger brains than we do, and they don't fight silly wars, so can we really be objectively sure that we're the most intelligent of the two?
