All animals have some characteristic number of chromosome pairs. We humans have 23 pairs. To be sure some people are born with 24 pairs, but so far as I am aware none ever has any grandchildren. So since I expect that you believe animals started out with just one chromosome pair you have to explain how we gradually got from 24 or 22 pairs or whatever to 23 pairs.
And I didn't say anything about Genesis. I don't pretend to know how we got here. I can only be certain that some explanations are not true, and one of those is the one attributed to Darwin.
Let's see--if you truly do not literally believe the creation story as presented in Genesis, then do you believe that life was seeded here by extraterrestrials? And if you don't believe that improbable story, either, then why not just accept the scientific evidence? There's a ton of it out there, from paleontology to astronomy to geology to biology of many disciplines. You don't have to look for supernatural explanations to explain the evidence that's all around.
And, pray tell, what exactly is your "science degree" in?
Your question *was* ridiculous, stunningly so. Asking a scientist if she believes that complex organisms can just pop into existence--please, tell me you understand that there is nothing scientific about such a scenario?
As for the chromosome number, that isn't as important as having the proper number of genes, and that those genes exist in pairs. Chromosome numbers can change by chromosome fusion or breakage--as long as the number of paired genes isn't altered, there is no reason a human with a broken chromosome can't survive--as long as both parts of the broken chromosome have a centromere, so the DNA replicates. The characteristic of having two small instead of one large chromosome would probably be lost fairly quickly--unless that person is a member of a small isolated population, in which case the trait could spread over the whole population. The same would also be true of a chromosome fusion event. What you're thinking of, the people with an extra chromosome, or "trisomy", is deleterious because some genes exist in triplicate instead of in pairs. When there are 3 of the gene, too much of the gene product is made, and that has a ripple effect over the entire metabolism of the cell (and thus, the organism). If a piece of a chromosome is deleted, then there is only one copy of some genes, and not enough of the gene product is made--also bad.
Had time to think about that thing about the flight feathers evolving from down feathers only on wings yet?
No.
What is it that you do not understand when I say I haven't a clue how all we observe came to be? I don't think we have the capability to understand any more than a young child can understand where babies come from. Introducing extraterrestrials just pushes the question back in time.
And, pray tell, what exactly is your "science degree" in?
I have degrees in math and physics.

Just because you type the words doesn't make them true. We have no idea how one species might morph into another, but we do know that each species has a characteristic number of chromosomes. The title Origin of Species and first paragraph of it imply that Darwin will have much to say about speciation. Yet his magnum opus remains largely silent on the "mystery of mysteries," and the little it does say about this mystery is seen by most modern evolutionists as muddled or wrong.
