How does natural selection occurs

WebWe most typically think of natural selection working at the level of the individual, favoring those better at leaving behind more individual descendants. However, with a little imagination, we can see how natural selection might work at other levels of biological organization as well.

He thinks this work will inspire other researchers with large databases of data on humans to look at how selection operates in populations.
