Reddit reviews The Selfish Gene

Since most people here love Richard Dawkins, I'd like to throw out a book suggestion: The Selfish Gene. While he only talks very briefly about homosexuality, it's still a fantastic book that tries to explain some of our behaviors as a species by contending that we are primarily motivated by a desire to propagate our genetics.

He extrapolates on some fairly common homosexuality theories but the one I remember the most is the "gay uncle" phenomenon which essentially says that having a family member who puts his resources into the children of his brothers and sisters instead of his own improves the chances of genetic success, because even the gay person's genes are surviving if their nieces/nephews survive and have children. (This was especially useful when humanity existed in smaller tribes).

I definitely encourage anyone who is curious to read the book.
