It would seem that if the fittest survive, potty-trained babies would come in miles ahead of those that are not.
Just the simple ability to use the toilet, along with sleeping through the night, would make babies more fun to have around. There would be more of them.
Evolution is considered a theory. This means that it is accepted as likely, but still is not totally proven.
If evolution is true, then humans are way behind.
More specifically, we are talking about “natural selection,” where positive traits that strongly influence survival predominate.
The very presence of teeth that trap spinach is an argument against evolution. People with hunks of green matter in their mouths are not attractive, but still they have not dropped from the gene pool.
This means also that people should be getting prettier, but they do not seem to be.
In the nonhuman world, we see evolution all around us. The wall phone becomes the desk phone, then the cell phone changes into the smart phone, which leads to the iPad, which will become who knows what.
Prune juice evolves to Dr. Pepper, which in turn leaves behind its prunes in favor of artificial flavor. So we now have fake, sugar-free prune juice, whereas we once had a powerful laxative.
However, if you drink a large amount of Dr. Pepper, the absence of this effect is beneficial. Soda is now better than fruit juice.
In the world of humans, some things have gone very wrong.
If evolution is at work in human history, why do people get bunions? Bunions are neither attractive nor useful for the promotion of the species. One would think that bunions would have dropped from the genetic mix.
Diseases and traits whose onset is in old age do not count. Natural selection takes place in the child-bearing years.
Therefore, one cannot say that a theory of evolution is wrong based on sagging breasts and beer bellies. These are the result of gravity and years of bad habits.
However, proclivities toward cigarette smoking and eating double cheeseburgers should have dropped out generations ago.
While I generally believe in the survival of the fittest, I have noticed that I have survived. This in itself draws evolution into question.
