Woman and Mankind Author's Preface This book is an attempt to place the relations of Sex in a new and decisive light. It is an attempt not to collect the greatest possible number of distinguishing characters, or to arrange into a system all the results of scientific measuring and experiment, but to refer to a single principle the whole contrast between man and woman. In this respect the book differs from all other works on the same subject. It does not linger over this or that detail, but presses on to its ultimate goal; it does not heap investigation on investigation, but combines the psychical differences between the sexes into a system; it deals not with women, but with woman.
Restored[ edit ] Thanks for restoring this article. I have added a few examples off the top of my head to be helpful to anyone who checks this article for information. I will add more information later.
In grammatically gender-sensititve languages, the grammatical gender of the animal species name besides humans indicates the larger gender of that species. Therefore, the animal species name is grammatically feminine if the female is larger than the male, and vice versa.
This seems to be too broad. I can think of half a dozen counterexamples in Spanish and Italian off the top of my head. Thus, larger animals are masculine, while smaller animals are feminine.
Of course, "larger" and "smaller" here is intentionally vague and subjective, and this "rule" is still by no means reliable enough to use it for anything except where only a wild guess is the other choice. Men and women do not naturally have differing hair length. The drawing could be made better by giving them equal hair length, and the male a beard.
But even in this case, there are women who must shave or they will grow a beard any woman exposed to enough testosterone will grow a beard, as evidenced in transsexualsand men can readily grow breasts under the effects of hormones again, transsexuals can demonstrate this easily.
To be entirely accurate, sexual dimorphism in humans is very much strictly limited to resulting from hormonal differences, and to a degree much higher than any other species, there is a very low sexual dimorphism.
The gender cues that we interpret are very much not at all accurate indicators of true sex at all. Take any two pheasants of differing sex and you will readily be able to tell them apart.
The same cannot be done with humans. There are a number of androgenous males and females, that can make sexual distinction difficult.
What I have seen in some races is sexual dimorphism that is extremely pronounced. Indian men in the north of India are much larger and heavier than Indian women.
So what is it? I have definitely read both views. I think Britannica says social mammals like humans generally have high levels of sexual dimorphism, including behavioural dimorphism.
Can anyone give me a source for each opinion? Live long and prosper.
V Alastair Haines Evolutionary psychologists have done a lot of work on human mate selection including cross-cultural studies of expressed preferences. Paternal investment over evolutionary time should predict current male preferences regarding ideal age of mates.The majority of studies on sexual dimorphism focused on humans, apes, birds, amphibians and fishes, and usually dealt with sexual size dimorphism (SSD) as summarized by Blanckenhorn.
In particular, many teleost fishes represent interesting models for studying sexual dimorphism [ 9 ], but few authors have addressed actual shape dimorphism.

Countershading, or Thayer's law, is a method of camouflage in which an animal's coloration is darker on the upper side and lighter on the underside of the body.
