As it turns out, the population was probably pretty stable for a long time, then took a chug of rocket fuel around the point where we discovered agriculture. It has since slowed for various reasons.

We also live longer, it would probably have fluctuated a lot when we were beginning civilization. Women would have 4-10 children and half of those would die before age 6. Then half of those would die before age 20. Everyone else died at 40. I wonder how long until we can become 150 or 200 years old?


I don't think the average life expectancy of a newborn has ever been 18 years.

An average life expectancy of 40 pretty much meant that, if you lived through childhood, and didn't die in a war, you could expect to live into your 60s or 70s. The vast majority of the increase in average life expectancy that's come about in the last century has been related to the precipitous decrease in infant and child mortality.

Consider the two following cases:
5% die at 1 yo, 5% die at 5 yo, 90% die at 45 yo. Avg Life expectancy 40.8
25% die at 1yo, 20% die at 9yo, 5% die at 25 yo, 50% die at 75 yo. Avg Life expectancy 40.8

Clearly pretty different populations, same average life expectancy at birth.


True. The lower the infant mortality the higher the average life expectancy (Japan), or vice versa (Angola). But I think wars and famines are also significant factors. Could average life expectancy ever surpass 100 if infant mortality would remain at a certain number? I mean these are just averages. What if we didn't take infant mortality into account and just looked at how old people got
There is a biological upper limit. Only very tiny fractions of the population live past 95, and even more miniscule fractions pass 100. Sure, as population increases the absolute numbers of people living to 100 goes up, but as a percentage of teh population (and thus contributer to average lifespan) the number remains infinitessimal.

Pretty much, the human body has an upper practical limit to lifespan of around 90 years (with outliers, of course).

Also, I was making light of the fact that inbreeding is a prevalent problem in Iceland. There is even an iphone app designed to help prevent people there from inadvertently hooking-up with relatives.



Not sure where you got your information, or if I misunderstood your post, but Iceland has no inbreeding problem whatsoever.

That app was originally designed as a mobile version of the Íslendingabók (http://www.islendingabok.is/English.jsp) which is just an Icelandic genealogical database and the "inbreed" feature was added as a joke.. which most news articles fail to mention Smile

That, and the fact that an 80 year old today isn't in significantly better shape than an 80 year old 100 years ago.

People are living longer, not aging slower.

Evolution isn't likely to change this much, either. There's no 'sexy' factor for people whith extremely elderly grand and great-grand parents, so there's no selection pressure to increase lifespan beyond about 60 or so. Basically, once our grand children become teenagers* evolution is done with us.


*There's a secondary survival advantage to grand-parenthood; Children with living grand parents have a higher survival rate, and tend to be both physically more fit and mentally more stable. Living long enough to pass lessons in parenting and to support the raising of children is survival selective.

Arent we all inbread already, i mean if Adam and Eve were the first humans to walk here.. Common evolution theory doesnt offer much consolation either..


LOL

Be careful mixing science and religion like that. Someone's head is bound to explode.


A genetic "Adam" and "Eve" are accepted scientific fact now. Don't be so 1994 =p.



Hoho as much as I agree with "don't mix apples with oranges" argument I have to agree your Adam&Eve is absolutely perfect as example, well requires some imagination thou Lol

Of course, they didn't exist at the same time, and they weren't the only members of their species alive at the time.


I've puzzled over this. If we assume everyone alive today has four biological grandparents and each on of them has two psrents each.....

How many generations of humans had to exist to support todays population?

Or is it just a case of the very first 500 generatios had about 40 offspring on avg.

Mind boggles.



Much less, the average was more about 25/30 and exceptionally 40+, life was far ruder than we can imagine and human body despite being a fighter on it self there was no treatment for a lot of little things we're used to just open the box take a pill and go back to work the day after, back then you'd simply die in a matter of days because of a bad flew.

In about 100 years medicine and comfort increased living hope for about double minimum but population increased also at exponential rate, 2050 we should be about 9000000000 that's about + 50% in less than 50 years with consequences that might be more or less important if our society current concepts evolves or wants to keep its middle age model like now.

We are the next dinosaurs, and we don't even need an asteroid to help us out.
