Eli5: how are organisms instinctually attracted to features that improve survival?

315 views

For example, in humans it’s theorized that women with wider hips have a better chance of a successful birth, therefore men are more attracted to wide hips. Like how can my brain know that wide hips is a good genetic trait and pass this attraction to wide hips to my offspring?

That’s not how evolution works.

Example of how it works:

Currently, scientists have learned that deer are starting to migrate out of known areas of foraging and into deeper forests during established Deer Hunting Seasons.

This happened because ‘some’ deer randomly chose to migrate into deeper forests at the start of hunting season. Purely by chance. Those deer stood a much better chance of surviving Hunting Season than those deer that did not migrate. So, they bred more often and had new deer who grew up with the same migration patterns. Eventually, that sort of migration pattern is widespread across the deer population.

Evolution is about passing on traits that better enable survival.
