Built for the Stone Age - part two: Population

Uploaded by: lindybeige
Video Description:
There is much to say on this topic, and in order to get my point across in a few minutes, I did cut a lot of corners.
The main point is that human evolution happened when we were hunter-gatherers, not recently, and that there were an awful lots of hunter-gatherers in the past who took part in the great experiment that is human evolution.
If I were to shoot this again, I would rewrite the script. You may notice that the no-incest and one-child-only rules, while they work fine for a few generations, get increasingly unrealistic as you go back in time. Once you have about 500 people on the top row of the chart, you have enough for a stable breeding network. Some of those people would be so distantly related that they really should be allowed to interbreed. So, instead of the population of the past's doing nothing but dying out from some ancestral vast population, it could instead remain constant for a while. In reality it would have waxed and waned. Many people would have had several children, and many would have had none, and not everyone was monogamous, of course.
This one isn't really a comedy sketch, like the others, so I'd rewrite it as one to fit in with the rest.

Hmm Billions and Billions of peoplle. Hundreds of thousands of generations.
no evidence of any type of civilization before 5000 years ago. Talk about not making sense.

I debated for a while about whether to include this part, because the argument has cut so many corners that it is perhaps misleading. I'm not saying that there was ever a time when as many people were alive as now, but the key point of the sequence is sound enough: that evolution of Man's instincts happened when He was hunting and gathering. Two million years at 30 years a generation is 66,666 generations. That's a lot. 5000 by 30 is 167.

you are correct. ... ( 8 months ago by mejc2)

you are correct. 66,666 generations is too many starting with two people and an average population growth of 1%. Please note i said an average not a constant. there would be way too many people on earth. way more than 6 billiion actually 2.83625967 × 10^278. actually even an average growth of .25% would yeild 4.74284398 × 10^80. what growth rate is reasonable? an avergage growht rate of .1% yeilds 3.96140813 × 10^28.

Is this pure mathematical speculation, or are you actually factoring in the factors that affect the human population (diseases, availability of food and water, conflicts with beasts and fellow humans etc etc)?

He's done a fairly simple bit of maths. Yes, at times the population may have been stable, or declining, although I doubt that there was much of this because the diseases etc. that killed off people in one part of the world would not in prehistoric times have been global in effect. The central point is that however you slice it, people alive today came from ancestors, and there must have been an awful lot of ancestors. Population estimates are on the rise. Roman Britain at least 7 million.

I don't think the logic here is consistant enough, because the introduced assumption is 'assuming they're not incestuous', which are you go back far enough, no one even knows enough or feels enough to stop, meanng there's going to be amazing overlap.
As you add more people to the pool of peopel alive today, each of them will have common ancestors, lessening the need for additional ancestors themselves. Meaning the objection breaks down.
This isn't to support 'more alive today than ever'.

Yes, if you read the 'About This Video' section, you'll see that I admit to this. The only really solid objections I've had so far to my arguments have been to this part. It needs a major rewrite.

Not familiar with the term "Mjec2". I Googled for it and got nothing. Actually, after the last ice age, you get the end of the palaeolithic period, and then the whole of the mesolithic before the neolithic revolution (start of farming).

No, actually. Never had much patience with philosophy. I've always found science - the study of what is actually there, far more satisfying.
