#2The page is not loading some images, and loads others very slowly, which makes it difficult to see the phenomenon described in the post.
Might want to bookmark this and check it out later, after the HN traffic surge has died down.

#4That makes a lot of sense. When we lived in the wild discerning different shades of green would have been crucial. It is also known that women can see more shades of red, probably in order to be able to more effectively gather edible berries. Now blue, who needs it? ;-)

Blueberries?

#8Wow - green, the middle of the visual spectrum matters most. If only they had discovered this years ago there could have been some really good systems for sending color information by just doing intensity-red and intensity-blue.
Or Y-U + Y-V = YUV if you prefer.

Blueberries are native only to North America, so our hominid ancestors would not have encountered them.

No, sorry that's just nonsense.
We're less sensitive to blue light because there is less blue light.
The black body spectrum of the sun peaks at green (which is why plants are green) and tails of into red. Blue light is not only a proportionately small section of the energy output but blue photons have more energy per particle and so there are even fewer photons necessary to make up that section.
That said while I've heard the women have better red resolution that doesn't necessarily mean they're more sensitive to the color number one. and number two explanations like "so they could gather berries" tend to come from a desire to see women barefoot and pregnant rather than solid science.
