Everytime I read something like this I'm just awestruck by the vastness of it all. What's a few hundred million years in the whole history of the universe? Why then, are we obligated to act morally? What's the significance of anything we do only to have it all go up in a big huge blaze?
This is our future

Very interesting. They seem to be drawing pretty far reaching conclusions from a little bit of evidence. The smaller canine teeth implying that males have become cooperative instead of competitive? Is there an alternative explanation? Could Ari have figured out how to fight without biting? Would bipedality have allowed more punching instead of biting?

In places like Europe where tribes are disapearing (united Europe) Cristian religion is slowly vanishing, there is no need for it anymore (evolution). I would not be surprised if it would come back when other religions are becoming a more dominating factor. Evolution.

In any species where physically expressed traits factor into overall attractiveness, it takes far longer for these traits to no longer be seen as attractive than it does for them to no longer be effective. In short, genetically desirable traits often have a vestigial nature; they remain desirable in a mate long after they've ceased to actually be useful in terms of utility. So, even if you are correct and "Ari" did gradually adapt to a more human hunting/fighting style, the ladies would have still seen big teeth as hot stuff. The fact, then, that tooth size continued to shrink at least fairly positively indicates competitiveness slowed, or else Ari's with the most desirable tooth size would have propagated at the highest rate. This is borne out clearly in the case of the Sabretooth tiger- females found long teeth so attractive and males were so fiercely competitive that they bred to a point where their teeth actually became too large to useful. The "desirable" trait was literally killing their species, but the chicks still dug it. So, one of the most majestic species on earth died out so women could get what they wanted |
