Muscular Guys Have Been Weeded Out By Evolution

Panda's would be extinct if they weren't so freakin cute! From what I see around me, human society has largely become what used to be natural selection.

I am not saying that any of these programs are a bad thing, only that they seem to go against the idea of traits being selected by nature to be advantageous and thus ensuring survival.

I agree with this. As humans and having evolved into a very complex society with moral and social boundaries, we've developed a system where the weak survive very effectively.

That said, evolution/natural selection also takes THOUSANDS of years to occur (and is always an ongoing process). So now that we are a complex society which helps the weak, abnormal, whatever... evolution will take even longer.

Adapting to physical environments is the #1 factor in evolution:

Just like why Giraffes have long necks; it's because the ones with shorter necks all died out over a long period of time. They died out because they could not reach the tops of the trees to eat the leaves.

That is how we have giraffes.

natural selection is going on now through subconcious and hormonal response, men (generally are attracted to curvy women) not just physically but subconciously this makes them better at carrying children there is a talk about it somewhere on internet.

I will agree that we do have preferences towards certain types of women, but there are very few cases of human not reproducing because they are unable to find a partner. This in turn practically eliminates any kind of selection. I do think that we are evolving, as there will always be genetic changes. I just don't believe evolution is controlled by a natural selection process anymore.

You could argue that certain types of women are inclined to bear more children. Some religious groups have definitely used this as a means of increasing their followers. Not quite sure if I would accept it as a form of natural selection though.

No offense, but this is just a crock. Giraffes are not tall because they would die out if they were short. There are countless species of animals that live in the same environment and are much shorter than giraffes and they manage to live on just fine.

Just did a bit more research on it, and it seems that the consensus is that theory is an old theory. It was once thought that the long necks of giraffes were due to ability to forage, but I guess some new research shows that the main reason was for "neck-swinging mating battles."

Whatever that means... lol.

When they fight they use the necks like that but that theory is strange as well.

They grew crazy long necks for that reason...to fight over the ladies? hmmm...not sure I'm going with that either.

That's what she said. Sorry, I couldn't resist.
