I notice that you like to ask questions but not to answer them.
No, I don't think the story of Noah is precisely true. And I don't talk about plants because they obviously operate differently from animals and are distinctly different from animals.
Your link is silly. Just say it happens on a chalkboard and it does. Evidence is of little importance in such science. But if mixed up chromosomes are the key to transitions, then they should be occurring all the time. And there would be no reason for them to disappear once they arose. But we simply do not see such things among the reproducing populations of ANY animal. Do we?

Well neither do I. I think such an understanding of the story as figurative/ not “precisely true” in the context of Adam and Eve is both apt and relevant.
Yes, plants are distinctly different than animals. What about that fact can you tell me tends to make them NOT an example of how a population can easily change its chromosome number? WHY is it different between animals and plants as far as chromosome number?
My link is easily understandable and explains quite easily how chromosome numbers can change within a population. It is based upon evidence and an actual understanding of the molecular mechanisms involved.
We DO see chromosome differences in individuals - breakages or linkages in chromosomes - they usually don’t manifest with a phenotype at all, unless it is slight infertility.
And there would be reasons for them to disappear once they arose - if their nuber was different than that of the predominant population. Chromosomal segregation during gamete reproduction.
And mixed up chromosomes are NOT key to “transitions”. If you had understood the link he explained it quite simply as being the same information in 46 cabinets or the same information in 48 cabinets. There really wouldn’t usually be a phenotypic difference OTHER than slight infertility with the predominant population.
