Could 2 People Actually Repopulate Earth

Is it even possible for 2 people to fully repopulate the Earth? According to Adam and Eve, it is, but there are some serious dangers of inbreeding that could kill off the next generation before they even get started. Don't miss today's new experiment to find out if the Bible creation story could actually be true.

If their children, instead of paring off, mated in a matrix, with each male reproducing with every female (and vise versa), after a few generations there would be huge matrix of combinations. There would, of course, be a lot of genetic problems, but there would also be a large number of viable offspring. If the problematic people didn't reproduce, there would eventually be large, genetically diverse and stable population.

I can tell you of a bird that was reduced to just one female. The Chatams Islands Robin. In the late 1970's it became critical. By the time it was attempted to try to save the bird there were two females but then one died without offspring leaving just "Old Blue" and a handful (single figures) of males. But the old girl with help did it and produced offspring. Today there are maybe 300 birds all directly descended from "Old Blue".

[@vic5015]

As a practical matter, the answer is no. You need a minimum number of people to maintain enough genetic diversity to avoid long-term problems (something called "the founder effect" or a "genetic bottleneck" in Biology). I've read that that minimum number has been estimated at around 50,000 individuals. One of the reasons scientists are so worried about the cheetah population is that, not only are their numbers low, the species shows indications of exactly this sort of a troubling lack of genetic diversity.

In one of his non-fiction articles, Isaac Asimov wrote that a colony ship should have at least 1,000 people to ensure enough genetic diversity. It's possible that with genetic screening, that number could be reduced safely, but that's not helpful to the protagonists of this video who are attempting to repopulate the earth, or at least their neighborhood. (What might be helpful is the fact that our written works seem to remain available to them, and the kids could research how to get medical science back on track.

I think you're mixing up your scenarios. If both parents have brown eyes, but carry the recessive blue eye gene, there is a 25% chance that the offspring will have blue eyes. There's a 25% chance the child has two brown eye genes, which results in brown eyes. There's a 50% chance the child has one brown and one blue, which also results in brown eyes.

This dilemma forgets to include issues regarding the risks of childbirth. Without functioning hospitals, and no nurses or midwives to assist them (presumably just the husband, a baby delivery guide, and whatever pain relievers they could scrounge up), the woman could have a much higher risk of maternal and/or infant mortality. Obviously it's doable, our ancestors were able to have kids without modern healthcare. But each time she tries to give birth, she's potentially gambling her life or the infant's life. For comparison, in England and Wales in 1895, the maternal death rate was roughly 650,000; globally in 2017, it was a little under 294,000. In ancient Rome circa 200 BCE, the infant mortality rate was 30%; globally in 2017 it was 2.9%.

The best way to increase their chances would be to do away with the idea of monogamy. For instance, ideally each of their ten sons would have at least one child with each of their eighteen daughters, with each successive generation similarly mixing and matching to minimize the compounding effects of inbreeding as much as possible.

That's actually shinking the genepool even more then having one sibling with one. Who's to say they didn't do polyamory? After all there were 18 daughters and 10 sons.

This is based on no scientific knowledge at all on my part, just wondering whether, in the absence of any ability to do genetic testing, looking for differences in appearance might be a strategy to hopefully choose a mate who overall has fewer genes in common with you.

[@samuelvink1482]

Yes I think this is the way. I have two siblings and we have always thought me and one sibling looked most similar. After DNA testing, it confirms, us two are the most similar and me and the other sibling are the most different. Them two with each other are in the middle. So I would argue, yes, looks do give you an insight into how similar siblings are on a genetic level.

No, actually if the breed a lot ( let's say each of the 10 male kids has 2 kids with each of the 18 females leading to around 360 kids) no imagine even as high as 95% of them die before they are old enough to breed around 18 kids still survived(considering they survived they have a lower chance to have a recessive genes as the ones that did most likely died, you know natural selection doing it's thing) let's say they weren't super unlucky to all be of the same gender so they can still breed ( I am gonna assume 12 males 6 females in case they are a little unlucky) if they all once again breed a lot ( each males has 2 kids with each female so around 144 kids) now let's say this time a lower portion of them die because as I already mentioned their parents were less likely to have bad genes ( let's say only 50% die, lol I just realised most of them would have to see hundreds of deaths) so around 72 survive long enough to breed. Let's say they aren't super super unlucky and all 72 are not the same gender( the chances of that happening are too low) I am assuming around 30 females 42 males ( so once again lot of breeding and you end up with around 2520 children out of which around 1260 make it to breeding age) At this point, they should breed (over 420,000 kids)and then spread out into 4 to 5 groups so that when they all adapt to different surroundings the groups slowly become more distant allowing for genetic diversity So, yeah they can do it as long as they breed alot and aren't super unlucky.
