AND you have lost your audience at word #2.
Indeed! Darwin’s thesis can be boiled down to three words: Selection Happens Naturally.
This is correct, and groundbreaking in it’s time, but we know so much more now than we did in Darwain’s time.
And I in turn, challenge you to build a Jabberwocky out of flim-flam the scent of the color blue.
Which is nonsense, of course, and having recognized nonsense (from the cover, no less) there isn’t much sense in trying to have a serious discussion about it. A serious discussion might include some current topics, like Epigenetic Inheritance or maybe Symbiosis. We could even discuss the origin and development of bones, or another feature.
The point is, that debate must start with some sort of established fact, like “bones first appear in the fossil record 540-550 million years ago.” If that point is agreed, then we can discuss how bones are thought to have developed. If not, then we need to find some more basic point of agreement.
But there is a corollary stating that people making such claims are never able to actually write down the math required to show this, much less submit them to a journal for review.
Most are “neutral”, which isn’t necessarily the same as insignificant.
A few might be detrimental. Most failed pregnancies (upwards of 70%) are thought to be caused by harmful mutation or genetic incompatibilities. This is poorly studied, for obvious reasons.
Somewhat fewer will be beneficial, and it may be hard to define what “beneficial” even means until the effects can be observed for several generations.
There is a large body of work on Population Genetics that covers this sort of thing in great detail.

I wonder how many people look at the small print figures for adverts claiming a large percentage of support. The sample is usually between 75 and 150 people!. I am sure someone can tell me what percentage of the population that represents.
Not this time - the % of the population would depend on WHICH population and how it was sampled. You are right to question small samples, but the real question often come down to determining just how large a sample is needed to meaningfully answer the research question.
From what I have seen here, scienctists use the same sort of tactic to “prove” their theories! (And mock me!)
Statistics are a tool of science used to help sort out meaningful differences from random variation. There are mathematical laws involved (Law of Large Numbers again), and defined methods for making estimates of values, measuring the precision and accuracy of those estimate, and for drawing conclusions (Inference) with known error rates (hopefully small). None of this is designed to mock you or anyone else, of course, but it might be a serendipitous side effect.

But it will sell well!
TENS of copies, I am sure.
