Could 2 People Actually Repopulate Earth

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.

    Of course they can if we are talking about repopulating abominations of SCP instead of humans.

    I can never get tired of your narrations ❤🥰

  3. dontgetrocked says:

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

  4. niyi ogunro says:

    Finally the question we’ve all asked but never really thought much of. I love this channel ❤️

    Yeah, wouldn’t want to have to know how this would really play out. Imagine matchmaking your kids and grandkids to “butter the muffin” with each other

    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.

      @Martin Benitez Its gonna be sparta for a couple of generations

    • ØØØ says:

      Wrong, because even if you select the good genes its most probably that bad genes might not be expressed and you will have severe deformities few generations later.

    • BrightForest says:

      Dude wtf

    • Martin Benitez says:

      @ØØØ that island example i looked into every one on that island is related to one man and the only serious issue is the color blindness even then its turned into a advantage they fish at night with torches that cause the fish to be confused they can withstand the intense light of the torch at night due to there eye sight issue there are now hundreds so they have a genetic pool now regardless of all being traced back to one person the habsburgs are a bad example cause they werent trying to make a population just keep wealth in the family so they didnt diversify after the first few generations

    • ØØØ says:

      @Martin Benitez being related to one person doesn’t mean they were inbreeding, millions of people are related to possibly a merchant from long ago in asia and oceania, that doesn’t mean that they were inbreeding

    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.

  8. Captain Marvel's Son says:

    I hypothesize that two people could repopulate the earth assuming each generation had many, many children through polygamy rather than monogamy. After only six generations there would be millions of people on Earth. The issue would be, after that many generations, all people might look very different from their 200 year old ancestors, wondering why they great-great-great-(x6)-grandparents look so weird.

      @Hazib Latson it’s not genetics. It’s simple math. If 2 people have 10 kids. Then each of them have 10 kids then you’re at 100 kids. If each one of them had 10 kids then you’re at 1000. If each one of them have 10 kids then you’re at 10,000. If each one of them have 10 then you’re at 100,000. If each of them have 10 then you’re at 1 million. If each of them have 10 kids. That’s 10 million people after 6 generations

    • Hazib Latson says:

      @Top Tier Tech Yea, see, that’s interbreeding. Over generations, it would cause accumulation of bad mutations and reduce population growth. Meaning, you won’t be able to reach even 100K citizens.

    • ØØØ says:

      @Hazib Latson they have no Idea of what they talking about, Bible brainwashed them

    • Hazib Latson says:

      @ØØØ They’re not talking about the biblical story, but the case in which 2 people are left on earth.

    • Hazib Latson says:

      @ØØØ But I suspect him to believe that too..

  9. theScottishKoala says:

    Wouldn’t travelling across the world through different environments and climates, different diets etc., encourage more genetic mutation and therefore diversity? At least over time. Just a thought

    • Oliver Cook says:

      Ya even if they did have the time it would only change a tiny amount of there dna

    • Thom Hendriks says:

      Genetic mutation is not really something you can push for. There is a small chance with each kid for a mutation. And if the mutation is beneficial, like better sun resistance, the kid will be stronger and more reproductive. But if that kid is born in the colder regions it will be less beneficial. So it is all just luck and chance, and will take tens of thousands of years to have a real influence on the gene pool

    • LeafyBoi says:

      @Thom Hendriks you can push for it looking at dominant or recessive genes

    • ScientistX says:

      @Thom Hendriks selective pressure increase also increase the chance of benefical mutation for that enviorment rising to prominence though all humans are born with at least 40 new mutations but under high selective pressures if any of those mutations are benefical chance of them becoming common increases massively

    • klakiti says:

      You need thousands of years for that. It doesn’t happen over the span of a few generations, let alone two people

  10. Justin Shim says:

    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.
