View Full Version : Sufficient humans to repopulate?


Specialist
07-03-03, 12:02 AM
I was wondering if 4 males and 4 females is sufficient
to repopulate the human race. If not that what is
the minimum?

In terms of repopulating is 6 males and 2 females
equivalent to 4 males and 4 females?

EDIT: fix female

I'd say a lot more than 4 and 4, and more women than men. Maybe 8 Males and 20 females to keep the grandkids from being "slow" after inbreeding.

id say 25 females and 10 males might be suficiant. ideally they should be as genetically divrse as possible. try geting mice (they breed relitivly fast) and have sevral big cages w/ difrent numbers of mail and female and see wich cage after a few years has only retards. mice and men are similar.


actually that wouldnt hellp at all but arnt mice just so cute!

If you let the mice produce as many offspring as they possibly could in a competitive enviroment I think they might do better. The retards would be outcompeted by any nonretarded siblings.

Just because the resulting mice might be nonretarded dosnt mean they would in any other way resemble their ancestors. Most new breeds of mice were originally developed through inbreeding.

a single pregnant female could be enough

there is a lot of data out there asking and trying to answer this question with a variety of different organisms

may i suggest going here http://www.ncbi.nlm.nih.gov/ , choosing pubmed, and search databases using some search term like "founding population" or "minimum viable population"

:rolleyes: obviously genetics isn't either.

tell me how a single pregnant female can repopulate a entire species? Don’t tell me: her son going to mate with her or no to twin a male and female? Unfortunately this kind of inbreeding would most likely result in still-born or infertile children after 2-3 generations.

Clockwood
07-06-03, 10:40 PM
The buildup of "bad genes" (usually recessive) is what causes problems for inbread animals. These can be removed by natural selection.

If she has 12 offspring every 3 months (being a mouse) and each of her offspring has 12 offspring every 3 months you will have a sizeable breeding pool. Many will suffer nasty side-effects from the inbreeding but some will most likly not be carrying any debilitating recessive genes. They will breed far more than those afflicted with genetic disorders and live to do it again and again. Thus the species continues.

Human women can't breed that fast though.

paulsamuel
07-06-03, 11:19 PM
genetic problems depend on the load. if the recessives aren't present, or can be weeded out, then no problem.

Clockwood: actually, Templeton wrote a paper based on data for Speke's gazelle (breed once per year, i.e. less frequent than human female) and reported the load was eliminated.

So, it could be done with humans. Which is my point.

If you're gonna argue with me, you ought to do the literature search first.

I'm sorry I though I already posted a reply to that, mut be the insomina getting to me.

No I don’t believe you could ever find humans without any recessive genotypes, in the inbreeding the recessive would build and the resulting offspring (if fertile) would be very genetically distinct from the original species, if you don’t believe me I take this from a seminar by a ecologist that calmed he was having the same problem with a group of moths he is try to perceiver here in Minnesota.

paulsamuel
07-07-03, 03:34 AM
you are my bitch!

finding a human without recessives is irrelevant.

you continue to refuse to learn. you just need one with no or few deleterious recessives.

your contention is that there's no one in all human future and history that would not have deleterious recessves.

i'm saying it's possible, and if this individual is female and pregnant, then that's all you need, and not even that extreme. some deleterious recessives are allowable if they can be weeded out.

Exactly.
But usually when that happens the species starts to evolve into a new one. At least from what I've seen. I find it very interesting, its seems very convenient, if the numbers are that low somethings not right and walla, they evolve.

it is difficult to predict selective pressure that will drive evolution of a species. There is no reason to assume that repopulating a species from a single, or a few individuals will seriously change the essence of the human species. We are already quite good opportunists. If we do not need to change our lifestyle, then there might not be any different selective pressures than right now, with a population of billions.

spuriousmonkey
07-07-03, 04:02 PM
A second example is Speke's gazelle. The entire North American herd was derived from 1 male 3 females. Obviously, from very first generation, all individuals breed in captivity were related (all had to have single male founder as a common ancestor). Hence, pedigree inbreeding unavoidable. Thus, founder and bottleneck effects promote rapid increases in pedigree inbreeding.

almost one.

Yes almost, but was the species recovered or is this a new species now, see the question was how many do you need to repopulate the species without result in something that is genetically and phenotypically distinct even incompatible, from the original.

ElectricFetus

And with just one how would that work? Unless it hermaphroditic?
Even so the amount of inbreeding would be so intense that very few offspring would survive and if any do they did would most likely be genetically distinct for the original.

the thing is of course, that scientists make inbred lines all the time. And they thrive in the lab. The lines do not perish after 2-3 generations. They thrive for decades and decades. Would something similar then be possible for humans? Is there any theoretical hindrance to this notion, or is it just because we were taught that inbreeding is bad and will weaken the spine, similar to masturbating.
If I summarize the matter then Paulsamual has good reason to believe that it is possible to create a stable population through inbreeding and this notion hasn't really been refuted anywhere here.

And we may continue to attack his 'aggresive' style in this case, but this aggressive stance might be induced by other people's shameless intrusion into his subject, without acknowledging that they could be wrong, or even contemplating that they might be wrong.

But I am not really an expert on this subject and I find it difficult to judge, but I do know that I had similar experiences in this forum and that it is difficult to remain 'cool' in these cases. Especially because most sciforumers can't really know who they can trust or not. And they will just trust the person they have seen around most, or like.

Is this about being right. Not really, it is about intrusion. Someone comes into you backyard and starts throwing in the windows of your house.

07-08-03, 08:48 AM
So I take it 1 female is enough. What would cause enbreeding kids to not survive? Is it some DNA that's mutated but we require later in life which is the source of the problem? I just can't comprehen why two similar DNA can't repopulate and diverge over time.

ElectricFetus
07-08-03, 09:01 AM
The problem is that everyone carries recessive traits (aka Gene that don't work right or well and are covered over by dominate ones) when inbreeding there is a much higher chance making children with homozygous recessive genotype, there are many recessives that are lethal or greatly debilitating but in a population with a good gene pool the chances of making homozygous recessive in one of those lethal traits is very low.

paulsamuel
07-08-03, 03:21 PM
you are right! it can happen although there are potential problems.

recessive traits are not necessarily deleterious! wellcooked is wrong when he defines recessive traits as 'genes that don't work well.'

the problem with inbreeding is called inbreeding depression, which is a decrease in fecundity due to inbreeding (it merely means a female is less reproductively successful over her lifetime due solely to inbreeding). the reason for inbreeding depression is expression of deleterious recessive traits. this happens at a low rate. the rate and the amount of inbreeding depression is entirely dependent on the genetic load of the population. But with a small AND inbred population, chances are increased that, merely by chance recombination of traits, that a whole breeding season is unsuccessful, and over time, the population can go extinct.

it is NOT that inbred children don't survive, most survive fine, but even one less successful offspring, due solely to inbreeding, is measurable and called inbreeding depression.

ergo, wellcooked is WRONG when he says that it can't happen

ElectricFetus
07-08-03, 05:07 PM
They don't work in competition to dominate traits. Again I did not say it can't happen I said it was unlikely to happen. paulsamuel has a ego problem Specialist, you see his life is not good enough for him so he has to come here to push people around, he will interpret any vague or with exception statement as wrong so that he can show-off, he will also not respect any neutral answer such as mine where I say it unlikely to be successful he interprets that as it will never happen so that he can hammer me on his own Straw Man fallacy… it pathetic really.

Recessive traits are any traits that only function when an associated dominant trait is not present. Red hair is a recessive trait. In fact it popped up several times in human history due to moderate amounts of inbreeding.

ElectricFetus
07-08-03, 10:16 PM
paulsamuel,

Do you know what a strawmen is? Lets clarify that first:

Person A has position X.
Person B presents position Y (which is a distorted version of X).
Person B attacks position Y.
Therefore X is false/incorrect/flawed.

You have been claiming that I’m wrong for saying a single pregnant female cannot beget a species, I never said that.

In reality the recessive trait never works or does not works as a efficiently as a dominate this is way the trait get cover over. White and red rose is a good example: a white rose has 2 recessive versions of the red rose pigment gene or gene related in that pigments production, when a recessive and dominate are together in a heterozygous pair the Rose appears pinks because its only producing half the pigment a double dominate homozygous would. There are also stages of recessives and dominates and many exceptions to the dominate/recessive rule.

paulsamuel
07-09-03, 12:27 AM
you don't even know what recessive means.

recessive genes are not expressed except in the homozygous state

the rose example is partial dominance or co-dominance

which means that in a heterozygous paring by your logic they are not expressed which means that the recessive trait does not appear in the presence of the dominate, perhaps my laymen terms are to beyond you, which is weird since most people have problems with words with many syllables not the other way around.

This would seem to support WellCookedFetus's position on HUMAN
repopulation of a species. Low birth rate, usually only one offspring
produced at a time.


A multilocus stochastic model is developed to simulate the dynamics of mutational load in small populations of various sizes. Old mutations sampled from a large ancestral population at mutation-selection balance and new mutations arising each generation are considered jointly, using biologically plausible lethal and deleterious mutation parameters. The results show that inbreeding depression and the number of lethal equivalents due to partially recessive mutations can be partly purged from the population by inbreeding, and that this purging mainly involves lethals or detrimentals of large effect. However, fitness decreases continuously with inbreeding, due to increased fixation and homozygosity of mildly deleterious mutants, resulting in extinctions of very small populations with low reproductive rates.

If you would mine put up better evidence on your part that actually from the article then we might also have proof that you actually read it as well.


we work on similar topics in the broadest sense (they are more mathematically oriented and use plant systems in their models while i work on real data and from animals) i.e. conservation genetics, and i know that they would agree to my answer to the original question while at the same time knowing the problems associated with inbreeding. this abstract, agrees with me, not with you.

i will say this again, and i cannot stress the importance of this enough, READ!

when you read you learn, you find more references to the topic, you'll find that the topic is not discreet and will link intellectually to a plethora of other topics.

a good rule of thumb is (and i know this is difficult, so don't beat yourself up over it if you can't do it continuously) one journal article per day. if this is too much, try one per working day (5 per week)

paulsamuel,

That’s strange you obviously did not read what I said, let me state it again: there is no proof you read it either, until then you have no valid argument unless you attack the article it self or present other articles. You really have a problem in presenting arguments: failing to have a proper premises or valid claims, constant use of fallacies. When you speak like a professor I will respect you like the one you claim to be, until then you nothing but a jerk.

I do have a subscription to Nature and SA you know, and I don’t pay for them to lay on my desktop either.

Ok, I'm going to pretend to be moderator here

let us try to figure out how we can resolve this dispute. We have seen some references, but with my layman knowledge I would venture to guess that this wouldn't so far exclude the possibility of a single pregnant female population founder.

So...for both parties. Can we summarize our main points and possibly give a reference to support our position. And if you still have time left, maybe argue why this reference supports your position and not the other.

You should be a mod spurious...

As for this thread, I am disgusted. Why are you people (paulsamuel and WellCooked, I'm looking in your direction) bickering like children? Don't answer that, it is meant rhetorically.

Anyways, the original question posed by Specialist, lest you've forgotten was this:

I was wondering if 4 males and 4 females is sufficient
to repopulate the human race. If not that what is
the minimum?
The answer, disregarding likelihood as it was not stated in the original question, is a single pregnant female. That's it! Conversation over. If his (or her) question were more specific, and perhaps asked what the minimum number for establishing a genetically stable human population with the least likelihood of failure, then I could see maybe having a disagreement. But that is not the case.

We are all here to learn, and it is incredibly difficult to take you two seriously when each thread is filled with childish insinuations and outright insults.

Grow up.

thanks Idle Mind!!

In the words of Mugato (of Zoolander), I thought I was taking crazy pills here!
