Do all deer share a common ancestor?

@John_Harshman

It isn’t. What you call “wild type” is just one of the many karyotypes, and all those karyotypes are in wild populations.

The standard chromosome count 2n=40.

@John_Harshman

What makes you think Mus musculus don’t have gene arrangement variation?

Do you believe there is gene arrangement variation?

@John_Harshman

What makes you think Mus musculus don’t have gene arrangement variation? And isn’t this a change of subject? Karyotype having failed you, you now resort to other differences? Incidentally, “gene arrangement” doesn’t mean what you seem to think, though in fact it’s not a term I’ve seen used in real biology.

No one has explained the deer chromosome arrangement other then to show the chromosome variation can exist between species.This is not new information.

@John_Harshman

Note that you haven’t answered the question: are all house mice descended from a common ancestor?

Sure in all the way humans share a common ancestor. Human populations also have karyotype variation. Why do you think they may have less variation then mice?

This is not a meaningful claim relatively to deer. You are comparing apples and oranges here. Mice are not deer in size, population sizes, reproduction rates and life span.

@John_Harshman

If so, karyotype variation is not a problem.

Another bald assertion to go with the only explanation for the “nested hierarchy” is common descent.

@John_Harshman

And isn’t this a change of subject?

Not at all. All evidence to this question “Do all deer share a common ancestor” should be discussed.
