Even beauty is based on your environment. In Roman does, larger women were seen as the most beautiful. That's why so many paintings in from that time period the women are a bit on the chunky size.
I agree but those standards of beauty range within a given spectrum. The average male prefers a hip to waist ratio of .7 . There are obviously some deviations from that average, but you are not going to find any large population of men that prefer a waist to hip ratio of .21 .
Finding a group of men that prefer a hip to waist ratio of .6 is not evidence that generally speaking human males prefer a hip to waist ratio of .7.
We need to be able to distinguish between the deviations in a given sample and not assume that they are evidence that the evolved characteristic is not present.
I would say that depends entirely on the people and what conditions they were raised under.
Why would you say that?
I am sure we can both posts hundreds of examples of peopling fighting over resources to stay alive, while the examples of people sharing resources or sacrificing their own resources for the benefit of someone who is not their genetic relative or assumed genetic relative are much fewer.
Again, because we are looking at the humans species as a whole, we need to be aware of the actions and tendencies of the majority because that is what we would expect the majority of people to be based on the statistics.
So the hunter/gatherer societies didn't collect food & resources communally and share?
I didn't say anything about them not sharing and in fact it would be expected that they would collect resources communally and share.
That is the whole logic behind being altruistic when it is in one's own benefit because we expect that our favors now will be returned later. If I was able to gather more resources than you today, I would share so that you would share with me tomorrow.
Sharing resources has nothing to do with the underlying tendency the we are still acting in our own best/self interest and that ultimately we care about ourselves and genetic relatives first.
Using the relatively unmolested remaining hunter/gather tribes as the best examples, I would say those communities don't resemble anything close to communism because there individuals are usually rewarded with more resources (women, food, etc) based on their contribution to the tribe with the tribal leader often receiving the most resources. So those that are more successful in the hunter/gather societies were usually rewarded with more resources.
Regardless of whether or not the members of the tribe share with one another, the division of resources is largely dependent on one's status within the tribe.
