A question about natural selection and its effect on behavior?

Question

How natural selection might act on such behaviors as mate selection, parenting, and aggression is controversial. How could natural selection have shaped the way that behavior is expressed in humans?

Answer 1

This, in reference to natural selection and behavior is only controversial among social scientists and humanities scholars; people who do not understand natural selection.

Any behavioral tendency, no matter how slight, that lead to increased reproductive success ( such as extending and extended child care ) would allow the organism to leave more progeny and these progeny would carry the trait into ever sharpening fitness and into the population gene pool.

This concept is not difficult to understand if you truly understand evolutionary processes and the endocrine/cognitive basis of behavior in all organisms.

Answer 2

Of course, humans have an added dimension over other animals, a more complex aspect . Humans can put a twist in natural selection.  At first, John Lennon made jokes about Yoko Ono but she kept up the chase even saying she would kill herself and she, finally, won him over. Why would a man with money and fame want to end up having a child with a woman that shows mental issues.  He had the option of thousands of beautiful women, women with money or fame.  This is not ordinary natural selection but human selection.  He chose a woman who would give interviews in the nude with him, to carry on an uncommon mental outlook on life. Humans select but not always as expected.

Answer 3

As the nature changes,  and this includes temperature..

The human emotions begin to alter and they change at random times.   If it's too cold you may feel depressed,  if its too hot you may be stressed out.  If it's snowing you may be happy and full of joy,  if its raining you may be sad and regretful.

Although for many people,  its different.  Some people enjoy rain (like me),   and hot weathers.  

So it really depends on your character and what type of weather you can take.  If things begin to change,  so will your emotions.

And mainly because it triggers memories.

Answer 4

Perhaps you need to address the oft repeated nature or nuture question in relation to behaviour. Aggressive males select desirable females. Successful parents are likely to produce successful parents.

Answer 5

Behaviours which lead to nurturing and foster an appropriate living condition for the offspring will proffer a selective advantage to those which such a genetic propensity and thus will lead to a more prolific continuation of this allelic frequency in a given population over many years.
