Women See Colors Better 103

Posted by michael from the fuschia-and-mauve dept.
fenimor writes "The results of the study by researchers at the Biodesign Institute at Arizona State University, suggests that natural genetic selection has provided women with a frequent ability to better discriminate between colors than men. 'Normally, this degree of genetic variation is suppressed through natural selection,' says Brian Verrelli, a researcher at ASU. 'In this case, nature is supporting a high degree of variation instead.' Because women have two X chromosomes, women can receive one chromosome with the typical configuration of the red vision gene while the other chromosome receives a slight variation. By contrast, men have one X chromosome, and any variation in the single red gene that they receive reduces their ability to distinguish between red and green."

    This isn't really news - it's well known that women have better eyesight, and are less prone to colour blindness than men, all due to that X-Chromosome.

    There was a story last year sometime (couldn't fine it, and was trying to find the article on Google - I'll try again and post a listing) where it claimed that someone women had an extra-sensitive sight for colours - especially shades of blue. Again, all due to them have 2 X-Chromosomes. One lady in the article was able to pick out a pair of shoes that were a perfect match for a dress she had purchased months back and was in her wardrobe since then.

      Actually, it's a sensitivity to red. Apparently some women (termed tetrachromats) have an extra cone along down the red way allowing them to make more distinction when there are red hues in a color. The article was in Wired if you want to narrow your search.

        I'm not sure that corn has a real flower that you'd recognize. You've got the tassel (which isn't usually yellow) and the silk - which starts out yellowish but browns after pollenation.

    My pet theory is that humans are selected that way because for millions of years as hunter-gatherers women did the gathering and men did the hunting. (Presumably, because it's harder to hunt with an infant, but it really doesn't slow down your gathering.)

    Women would need to be able to distinguish fine colors to tell plant features apart (poisonous, spoiled). If you make a bad choice, your group might get sick. Whereas men don't really need to distinguish colors as finely because an antelope is an antelope no matter what shade it is.

    A color-blind male won't hurt the group much. A color-blind (or handicapped) female would.
    • The last paper I saw hypothosised that color blindness is an advantage while hunting because everything is camoflaged so motion and shape cues are more important (which is what better hunters rely on normall). A colorblind male could potentially help the hunting group.
      • An aside on this: the military recruits color blind individuals very heavily. As it turns out, they make excellent snipers because they are not easily fooled by camo. The same problem was probably an advantage in some circumstances on the serengetti thousands of years ago.

          They do..? After deciding to join the service, I looked through the Army MOS specifications: less than 20 out of 200 jobs the Army offers allow for red-green deficiency. Specifically, the Army doesn't allow color-blind programmers (much less infantry.) Go figure.

        This is also what I thought as dogs are color blind and they are normally hunters. Seeing in black and white makes you see contrast better.

        As I understand some of the big cats (lions, panthers, tigers) only see in shades of green. Which is basically the same as being color blind, however the shades of green work out better at night (moonlight) time.

        The only species that need to see color are ones that eat fruit, to see if its ripe or not.
    • What I don't like about that theory, or at least my understanding from it, is that it sounds like women and men would evolve seperately.

      My theory is, colour blindness, like any genetic "defect" is recessive. And in the case of the gonosomes, men lack the usual dominant allele (in exchange for some other features)

      But in contrast to other genetic defects, for example cystic fibrosis, the phenotpye is less lethal. Hence it is more prevalent.

      The reason, that it is bound to the gonosomes can be pure chance.
    • Um, the reason women see colors better, according to the article, is because they have 2 X-Chromosomes. So, your theory implies that they developed with 2 X-Chromosomes, and men with one, due to millions of years of hunting and gathering?

      I am not sure that makes sense...

    • It's sex linked. The gene is deficient in the X cromesome and reccessive. I'm sure this is simplified as there isn't one colorblind gene. Girls require two colorblind genes to be colorblind, or they are just carriers. Boys have a 50% chance of being colorblind if their mom is a carrier. Fathers always pass their X chromasome to their female offspring (colorblind or not colorblind, mothers pass one of their two to their offspring.

    This is old news. Studies published in 2000 based on data from the early 90s have talked of the tetrachromat phenomenon. See this article [utk.edu]. There is even a mention of it in wikipedia. Some people [4colorvision.com] even think that all humans are blocked tetrachromats.

    • Close, I agree this is truly ancient news. However
      tetrachrmoacy is very rare (not the "frequent" the blurb claims) as true tetrachrmoacy requires the fourth cone to have a frequency response curve that is significantly different from either the existing red or green gone.
      • Accordind to TFA, variation between the genes which control red perception is very high - as many as 40% of women may have significant variation. That means that some degree of tetrachromacy is much more common than previously thought.

    Think about this. Suppose a little boy grew up in the woman culture.
