The Fittest Animal In Their Enviroment
Natural Selection- What Do You Mean?
Natural Selection is survival of the fittest. To be fit means to reproduce fertile offspring. Who is fit is determined by the environment they are in.
What Might Get Them To Be Selected Out?
Loins might lose their title as the fittest if a genetic mutation happens and that causes them not to be fast anymore. If they aren't fast then they will get killed a lot and they won't be the fittest. Another example is if they lose their food source. If that happens then they will get weak and eventually die out.
