This is getting repetitive and, as it typical for your cult, attempts to drown the opponent in irrelevant detail, verbosity, and silly illustrations.

I responded to your zebras about a week ago. This is selection, not “evolution caught in the act”. “Descent with modifications” is a fantasy not observed among birds or mammals.

If there is anything you introduced in your last post that I did not react to, kindly point that out.

annalex: "“Descent with modifications” is a fantasy not observed among birds or mammals."

So now you claim that neither birds nor mammals experience genetic mutations from one generation to the next?
And your scientifically recognized source for this choice bit of misinformation is what, exactly?

Here's the truth of the matter:
Evolution consists of two key factors: descent with modifications and natural selection.
Since you have already admitted the fact of natural selection, I won't spend more time on it.

Descent with modifications begins with genetic mutations during reproduction.
These have been observed and confirmed innumerable times -- so they are facts.
How many mutations for each generation?

First, remember that the human genome -- the genetic code, those biological instructions by which DNA makes us -- that code has about 3 billion individual "base pair" instructions.
Not all perform useful work, a good many are sometimes called "Junk DNA", and mutations to "junk base pairs" have zero effect.

The previous estimate was about 100 mutations per generation, but this new study reported high variability in the small sample, and one can imagine mutation rates increasing during times of high physical stress caused by new environmental factors.
In other words, individuals highly stressed by a changing environment might generate more mutations than others living in more species-friendly locations.

Regardless, "descent with modifications" is a scientifically confirmed fact.

So what exactly is your problem with it?

You have seriously responded to nothing, whether zebras or humans or anyone else, FRiend.
