Ummm... None? We would need more light. More light= more electricity.

We would evolve the ability to see in the dark over time. If it happened before electricity was discovered we wouldn't need electricity as much and there would be a signicant difference.

It's already happening in China. A boy has cat-like eyes that enable him to see in the dark as good, if not better, than in daylight. http://www.odditycentral.com/ne...-the-dark.html

The link was broken. I'm frustrated. I want to see the cat boy.

I don't think evolution works like that... In fact, I know evolution doesn't work like that.

Why would we evolve if we can already see during the day? You really need to brush up on biology...

When did I say we needed to? I said it would have saved electricity, which it would.

Not to mention the additional energy requirements for staying warm.

I think you mean if humans could see in the dark or something.

We'd probably be able to see in the dark if we were nocturnal.

by Anonymous 11 years ago

Nocturnal primarily means active at night, not sees in the dark. Although, over time we would evolve to see better at night. However, we currently use lights, so if we were to suddenly become nocturnal instead of diurnal, we would use more electricity because our eyes wouldn't be used to it.

Right, I was more going by that they would be nocturnal, rather than just randomly become nocturnal one morning, because that seemed like the more sensible way to take it.

I said "had become" as in over the course of time.

No we wouldn't. Mutations don't occur in response to environmental pressures; it's the environmental pressures that make mutations useful. Or not.

I get what the OP is saying here in the comments. There's like something in evolution where a species would change to cope with the environment. Or something like that Example: http://www.omg-facts.com/view/Facts/34595

Evolution does not occur in response to the environment. These elephants just developed a random mutation - RANDOM! And that mutation meant they don't grow tusks. The mutation is only becoming more prevalent because nobody wants to have to deal with a heavy elephant that has nothing they can cut off it and sell. So sure, the new allele is advantageous, but it didn't occur in response to the environmental pressures.

But then we would have to develop a way to darken the environment during the day time, because nocturnal species stick exclusively to the darkness. It would pretty much be the same thing, just switched.
