It is a truly beautiful thing.
Ian4 said:so the big question is: if these people have lived so long, why haven't they spread their genes? because obviously these people have very strong genes if they live to that sort of age. but the only way for their strong genes to survive is through procreation.
i found the answer to be just as interesting... it's because nature wants people to procreate. if you don't procreate, nature wants you to keep living until your genes have been passed on. and once you do procreate and your genes have been passed on, you become expendible... so you tend to die younger.
Ian4 said:very enjoyable documentary series hosted by richard dawknis is on sbs at the moment. the series is about how society goes about keeping its morals and values in a world that is becoming more secular.
the episode i watched the other night was about sin (with a focus on sex). there was one discussion which really piqued my interest.
dawkins had his geneology mapped (which was interesting in itself), which it led to a discussion on evolution. if darwin's theory states that the fittest and strongest survive and multiply, then how does evolution explain how one third of the the people in the world over the age of 100 alive today are actually childless? when you think about it, this is an incredibe statistic. i don't know what the percenate of humans that have never had children is, but i would expect it to be extremely low... less than 5% perhaps? maybe someone can provide this stat?

Azza said:There's no evolutionary value in living beyond child-bearing age. A more interesting stat would be the proportion of childless women at menopause.
Ian4 said:compare the amount of childless people at age 50 compared to the age of 100. i'm tipping it won't be anywhere near 33% at age 50.
Ian4 said:i've pretty much made the decision that i will never have kids.

Panthera tigris FC said:That is an interesting question.
One hypothesis is about the value of grandmothers in rearing their grandchildren.
Azza said:Good point. Although in times of scarcity feeding an extra mouth would work against that to some extent. Complex.
mld said:WTF evolution, are you drunk?
Panthera tigris FC said:Indeed. Fascinating stuff though.
evo said:yo Pantera, was at the Tote last night watching a couple of Geelong punksters you may remember from back in the day? good times.
