Evolution is a change in physical or psychological characteristics of a species over several generations. This change of characteristics is often brought upon by environmental distortion through the process of natural selection. A variation could include having different colors or for a bird wider Beak. In a dark environment those with darker colors would have an easier time surviving than those with lighter colors. In a forest where there are only hard seeds, a bird with a wider beak will have an easier time breaking those seeds than those who don’t. Those more advantageous traits will help those creatures survive better in their environment and pass on their genes unlike those don’t have useful or straight up disadvantageous traits will struggle to survive or just go extinct. Over a couple of generation only the with those useful traits will be left.

Here is an example let’s say that there were large amount of bears with black fur living in a deciduous forest environment. There are also a very small number of bears with white fur also living there. The black bears would have a clear advantage over the white bear when it comes to catching prey as they can camouflage and since they are bears if winter hits they go into hibernation so having white fur wouldn’t help as the whole point is to grow fat and go to sleep. Now let’s say an ice age happens, those bears who are out of hibernation have to deal with a cold environment all year long. Now that black fur that help those black bears thrive by Camouflage are now a clear give away but white bear can blend in perfectly with their environment allowing them to hunt. Over a few generations the majority of the bear population wouldn’t be black but white.
