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.

Elie, Aden, Carl, Asher, Sebastian all start with the same letters as Eve, Adam, Cain, Abel and Seth
Nice detail

Don't need to watch the rest of the video to figure out the human race is doomed in Aiden and Ellie's hands.

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've always wanted to know the answer to this question for at least 10 years. Excited to hear your response!

[speedytruck]

Ellie should've visited the nearest cryobank. Those robots can't have possibly targeted those before vanishing :)

I'm reminded of the "Dark Eden" trilogy by Chris Beckett. The setting is a world populated by the descendants of two stranded astronauts - the technology level is essentially stone age, but a few artefacts of the original astronauts are still kept as holy relics, various genetic defects are rife ("batface"/cleft palate and "clawfoot"/club foot in particular), and an interesting culture has arisen.

Paradoxically, the answer to indreeding is redundant breeding. That was the case with small prehistoric isolated tribes. They knew no contraception, had many babies, and many of them died from inbreeding burth defects. But the ones who randomly had good genetic combination, survived.

As far as small gene pools are concerned, cheetahs are thought to be one of the smallest. DNA studies show that they may have about 70, 000 years ago cheetahs been reduced to maybe as few as 4 animals. They are so genetically identical that all cheetahs are virtually brothers and sisters.

I love how that brief aside about one of the children murdering each other just plays out in 5 seconds and is quickly glossed over.

First the poor Ellie would have to survive childbirth / labor, hoping the guy who survived has good skills as a doctor and will not make her pregnant every year or she will die before she can make enough babies to worry about inbreeding.

I remember hearing about a town in Italy, Stoccareddo, where almost everyone has the same last name, Bau, and most likely everyone is related. Almost everyone has red hair. They also eat extremely high fat foods and high sugar foods but have a very low occurrence of heart disease and diabetes. A majority of the population lives well into their 90s and 100s.

Didnt even realise 13 minutes had passed. Great cider man👍

[acmenipponair]

Ellie should just become a genetic scientist and check for the DNA of their offspring and those with "problematic" gene poles are paired together with those with more favorable gene poles. With this method she could breed out most of the problematic genes while endorsing the favorite ones.

So basically it'll depend on how genetically gifted the two last people on earth are? If both have an incredibly tiny portion of negative genetic mutations, there would be a higher probability of things working out. If both were genetically perfect (is this even possible?), Then I can imagine things working out with quite a high probability.

[vic]

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.

[DarkFrozenDepths]

Basically what I got from this is that if someone ended up in this situation, then you basically have as many kids as possible like you're constantly trying to play the lottery

[shawno]

In the case of Adam and Eve, it is assumed that they were created "perfect" and didn't have any negative genetics. It took several millennia in a fallen world for genetic mutations to manifest in humans to the point where they are today.

Deadass props to the writing team. You guys always got some crazy creative stories I wouldn’t think of in a million years.
