What do you think "fittest" mean, in biology?
There are common misconceptions that "fittest" mean the "strongest", "fastest" or "smartest" or any of those combinations.
I am sure strength and intelligent can be factor to survival on a personal or individual level, but in biology, especially with evolution...
- they are not talking about individuals, they are talking about population...
- ...and fitness mean to "fit in" the environment they are living in. Hence, finding a niche to fit in.
To give you an example what I mean by fitness and survival, let look at any of the current species of butterflies. Now, I cannot tell one species from one another, because I am no expert in butterfly or any other insects for that matter.
Now let me ask you the following questions:
- Do you think a population of butterflies continue to live because they are the strongest insects?
- Do you think butterflies survive because of their speed?
- Or do you think butterflies are genius?
So if butterflies are not the smartest, strongest or fastest of creatures, and they are prey to many different other animals (predators, such as birds, lizards, praying mantises, etc), then why are they still around?
And the only places that I don't think butterflies don't live in, are the polar region, and possibly in the most arid lands (I am not sure about this last one, because I don't know enough about butterflies, and I don't know about wildlife in the deserts, so I am only guessing here about arid deserts).
They are around and not extinct, because they apparently found a niche of where they can survive and live. They have adapted, evolved - they "fit in".
Evolution is more than just about the survival of strongest or the smartest. In fact, evolution showed that survival are for the weakest as well as for the strongest, for the dumbest as well as the smartest, for the smallest as well for the largest.
So if you think fittest only mean mean creatures that possess strength or intelligence, then you really don't understand evolution at all, savagewind.
