Let's see.... what I can buy with my $0.02 today...
Well, as far as hair length, Long hair signifies femininity, submissiveness, and fragility.
While short hair signifies Masculinity.
The reasoning for this (At least to anyone descendant from Near roman lineages) was due mainly to Battle.
In battle, Long hair was a detriment, as it was something to grab onto to ensure your sword found your opponents neck.
So, men tended to keep their hair short enough to prevent it being used against them, and women used their long hair to signify health, differenciate
themselves from the men, etc...
Eye color, and Hair pigment are in fact, completely related functions of Melanin production.
There are basically two different types of melanin (Pigment):
a brown-black polymer of dihydroxyindole, dihydroxyindole carboxylic acid
And pheomelanin, a red-brown polymer of benzothiazine units largely responsible for red hair and freckles.
The main purpose of Melanin is to mediate UV exposure in the skin, and to thereby protect Nucleic DNA from the harmful effects of UV damage, and
subsequent mutation (See Also: Skin Cancer)
In equatorial regions, since the angle of sunlight is near vertical, and light passes through less atmosphere, there is more light to potentially
damage the cells.
In extreme northern and southern latitudes, there is less light available for the production of Vitamin D, and thus the amount of melanin must be
decreased for optimum body functions.
This is why the Mutation that produced light skin became so prevalent throughout northern Europe when it did.
The eye colors are somewhat related to such.
The default color for Hair is light Grey.
The default color for eyes is red (Blood Vessels)
Blue eyes are a combination of the Dark melanin pigment and the red eye color, that produce blue.
Brown eyes have much more melanin, and are thus darker in color.
Green eyes are a combination of Dark melanin pigment, the Red pigment (Yellowish) and the underlying red color of the blood vessels.
Blond hair color is likewise the normal grayish hair color, with a slight brown melanin tint.
Red hair is a result of the Grey hair color, with the Red pigment.
And Black and brown hair are the result of elevated levels of the Dark melanin Pigment.
