Perhaps in the case of brute animals,but IMHO this is questionable in the case of modern man because it's likely that anyone who has traits or ideas too far outside the norm will be destroyed by the masses or the political elite and not prevail and procreate.
As my friend Jo Kus once told me...
"IF man is the pinnacle of knowledge - why is it that man still continues to war, that man still is subject to the elements, that man is still having the same problems that "Moses" wrote about in the Torah."
In the competitive survival game, the unfit disappear. That is true of human and animal species alike. Adaptive behavior is survival.

As if reason is what makes the world go round...
