Rather than running experiments, instead data is collected. Genomic studies. Data falls in line with evolutionary theory, and helps define/refine evolutionary theory. Data also disproves creation of human by fiat or any kind of sudden, non-descent (YEC/OEC idea of human creation).
No it doesn't. Or at least your favoured chromosome fusion example
doesn't. Now before you have a go at me about what I believe, I'll
state right at the start that I believe in the reasonable hypothesis
that apes and humans are descended from an ape-like ancestor that had
48 chromosomes. I imagine it's possible to date (using genetic drift)
the time in history when the fusion occurred and that will verify it
was before humans came along. But I believe in long time-scales;
YEC's don't.
However, as we have seen from Dennis's explanation and the quote from
Darryl Falk, it seems the chromosome fusion is no big deal - it is a
microevolutionary step in itself that doesn't change the genetic
material. A heterozygous 47 chromosome (23+24) individual can mate
perfectly well with a 48 or a 46, and meiotic drive ensures the 46
individuals eventually take over the population.
Hence, a YEC could well argue that man and apes were created
separately, and the humans originally had 48 chromosomes.
You'll need a lot more than evidence of a chromosome fusion to
disprove that assertion.
