In the plant kingdom, each part has its own awesome story. So is in the animal kingdom. I love the lessons of my biology teacher, when he knows many correlations and he wants us to guess them. They are complicated but logical.
I disagree it is "so we don't die". If it was true, we could get subjugated by other species, afraid of them and hidden in the dark. It is rather "so we survive". In the past years, when average IQ increases, it is even "so we dominate".
