Homework Help: Science

Posted by Marie on Friday, July 27, 2007 at 11:50am.

Humans shape their environment in ways that other organisms cannot. Are humans subject to the same pressures of natural selection as other organisms?

Yes. If we are too weak or too lazy or too unfortunate to make a living, we will not survive. We can steal or grow our own food, but that takes skill as well. We shape our environment considering that we are high on the food chain; we are shaped by our environment considering that we cannot control everything.

No, we are not subject to natural selection in the same way other organisms are. Unlike in case of animals, for humans there is no strong correlation between being physically very fit and being able to raise your children well.
