Has anyone else noticed ...
... that there are no responses from Aristotle?

Any feedback appreciated

Regards, aristotle

So either aristotle is amending his opinions based on the feedback he has received ...

... or in typical creationist style, thinking he has an axe to grind, finds it is a toy rubber axe that bounces back when he tries to use it in a real axe fight, and runs away.

Enjoy

Yeah. I kinda stopped posting-in-order-to-get-a-reasonable-response-from-specific-people a long time ago.
I generally post because I'm bored and want to express an opinion.

And posting on this site makes me feel smrt.

I'm one of you smart people, right guys? Guys??

Actually I like the way that you frame arguments. You are smart enough...evolution has been kind to you.

Or could it beeee? *looks up towards sky, scratching his head...*

Or perhaps he is actually reading what everyone writes. Nobody limits their knowledge to just one source, do they?

The people we deal with here often limit themselves to sources that agree with them.

... less favored individuals reproduce more ...

In the ToE the one that reproduces more IS the favoured variety. The species will change if a new variety has an advantage in terms of offspring. If the existing variety has the advantage then the new variety will tend to be eliminated producing stasis.

In many cases selection does not favour either allele strongly enough for long enough to fix one of them, but when it does one of the alleles will be eliminated. So you are right that natural selection will tend to eliminate some alleles, narrowing the variation of the species.

This is why the modern version of the ToE proposes mutation as the mechanism by which new alleles are introduced into the species.

The observation of mutations producing new alleles in modern populations is also another reason that the ToE includes the process of mutations.
