The Human Sexes is an impressive series that brings to light many interesting human behaviors through out life. What should be the real Biological behavior of human bonds?. Are we biologically polygamous or monogamous?. Are modern societies pushing into unnatural behavior?. Desmond Morris did a wonderful analysis in more than 800 different cultures all around the world and is so trilling to see how many similarities in rituals are among them, like for example, the rituals from childhood to puberty or from single to married. Why in the industrialized societies is getting so difficult to find a partner and build a family?. How long could the human bonds survive? (in some societies seem that no even death is able to vanish them). Desmond Morris shows the result of his observations and provides also his conclusions. Personally I like his unbiased point of view since at any moment he maintains his neutral position as zoologist. A complete must for people that would like to understand that human sexes are equal but different.
