The woolly mammoth is strongly associated with the Ice Age, but they survived until surprisingly recent times in the far north. Recently, the genomes of multiple mammoths from the last surviving population on Wrangel Island were sequenced. The scientists concluded the population was founded by 8 or fewer individuals and only 1 mitochondrial lineage was among them. They also estimated that the population grew to a few hundred before finally going extinct. This, it turns out, is a wonderful natural laboratory for biblical events. Consider that there were only 8 people on the Ark. How much genetic diversity would we expect to lose? Is that population too small to prevent so much inbreeding that humans would have gone into mutational meltdown? Etc. Etc.
