Not since I'm in college.

The most important factor is increased homozygosity: Every human has two slightly different copies ("alleles") of the same gene in his DNA, one from his mother, one from his father- some of those alleles would cause or contribute to disease (for example because they are not working properly), but are kept in check by the second, healthy allele of the gene. Now, if you mate two closely related animals (who of course share many alleles already) the chance of getting two defect alleles for a given gene rises.

So, the offspring of related persons doesn't HAVE to be sick, it's just that the chance is vastly higher than in others. And of course it doesn't get better in time (with more inbreeding using the same varieties of the two ancestors).

That doesn't change the fact that a mammalian species with a mating pool consisting of a handful of directly related individuals can't survive. Within a few generations, Adam and Eve's descendants would consist entirely of potatoes and invalids, even assuming Eve didn't share Adam's genome (with her being created from Adam's rib).

Genesis really is just terrible story writing.

Yeah, well, that, or my parents just aren't trashy underclass citizens whose only effort of raising a unique, well-composed person was giving them some fancy name.

Oh my god, I love this reaction face.

Apparently knowing the mechanism of some obscure US game show is now an indicator of intelligence.

So....where are we going to migrate now that HL is predestined to become as cancerous as ***? Any ideas?

Extremely unlikely
