Why we have two Nostrils? [Biology]
posted June 28 2013 17:59.25 by Giorgos Lazaridis




Evolution usually gives nothing o excess. Two ears are used to locate the source of a sound. Two eyes are used to calculate the distance of an object. But two nostrils? Why? What if we had one big nostril instead? Would it work the same?

Well, it seems that nature wisely gave us 2 nostrils to perceive more odors better. Watch this video to see how the smelling system works.
