– The linked article is all I could find about men having better stereoscopic vision.
– All women being able to see a fourth primary color is not at all agreed on, but there may be some who can: http://en.wikipedia.org/wiki/Tetrachromacy
I don't see how either trait necessarily correlates with being a better hunter or gardner. Are people who see a fourth primary color better at picking the ripe tomatoes? Maybe. But it makes sense isn't science.
I'm pretty sure this is an urban legend. If not, all color theory through the history of art would be male-only. Women should have different screens (RGB would not be enough to show a realistic picture), different films, printers and so on. How can anyone seriously believe that?
The wikipedia article says that tetrachromacy is theoretically possible in women, and that two persons in the world have been identified as possibly tetrachromatic. That is quite a different issue.
It's basically impossible for us to comprehend how rich and colorful the world looks to e.g. birds which has tetrachromatic eyes.
In other words, if you want to see everything around you, your eyes should be far apart, but if you want to be very good at focusing on something you're hunting, they should be closer together.
Though I don't remember where I heard this, and hence cannot provide a citation.
Anyway, I'm certainly not arguing that binocular vision isn't good for hunting, I'm just saying that the extra few millimeters distinguishing men from women probably doesn't help much. I'm pretty sure men have more widely-spaced eyes than women cuz we're just plain bigger than women (a fact which _does_ actually help with hunting).
At the same time, if the traits are found in a large part of the population (50%?) the cause for their selection could very easily be related to acquiring food.
"They also prefer sites with moving objects, machines, tall buildings, violent themes, male figures and caricatures. Women prefer rounded lines, more colour and detail, unusual typography, static objects, low rise buildings, female figures and smiling faces."
And also why this matters:
"She said: "Organisations can either 'turn on' or 'turn off' their male and female customers. Studies show that if a customer perceives something as beautiful the are likely to pay up to 66 per cent more for the product.""
