The Human Price for Sight
« on: March 30, 2004, 03:17:08 PM »
Apparently there is evidence to suggest that the price of human vision(full trichromatic vision) was a loss of smell. 60% of the DNA used to detect odors in humans is not used as opposed to 20% in other mamals and 30% for non human apes.

You can read more about it here, if your institution has a subscription.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Lol! I would much rather have full color vision than to have a strong sense of smell. I'm sure food would taste better which is good, but for all practical purposes, we couldn't appreciate the value of appearances (e.g. the value of gold would probably go way down) thus good thing our DNA made us the way we are.  :coolio:
