If we evolved why did evolution stop? :headscratch:
-
Who says it did?
-
We peaked in 1975.
Been downhill ever since.
Standard cycle of nature ya know.

Better question... If we evolved from Chimps, why are there still millions of Chimps?
-
I think we are at our climax, not much to improve on, we are utterly doomed waiting for the next extinction to allow us to continue the cycle

That's racist yo
Pretty quick edit there Melvin.

Evolution requires an outside stress that has a favorable mutation in the gene somewhere that gets passed along and changes something down the line. Unfortunately, we've peaked and now can control nature for the most part, so no longer have an outside force driving a change in how we are. if anything, the fruits of out labor have allowed the less fit genetic material to be passed on because there is no interference from nature.
So until such a time as we all get super powers from radon gas, or the aliens come back to do it with us again, and hopefully not re enslave us, we'll be stuck getting stupider.

I think I read that in "Guns, Germs and Steel".
Like I said, we're devolving.

Only one possible location for this thread to lead to.
The only question is how long it takes to get there.

Here are some simple reasons to you answers:
Hardy-weinberg Equilibrium did not happen
Bottleneck effect happen in some populations
Founder Effect occured in some parts of the world
Punctuated Equilibrium

We are alredy seeing evidence of this.
Just talk to just about any PETA member or Vegan

Genetic mutations are still occurring.
At our max!? No way, why stop now?
Thinking humans are in control of nature is absurd. We are at the whim of nature's will.
IF humans are around in another million years, we will be a very different creature.

But we didn't :)

And it's only human mind that thinks in categories like "at the max", "top of the ladder" and so on. ;)

I think if evolution actually existed humans would have developed wings by now. To me the belief that an animal can change a part on its body over time because it needs it is absurd. The animal has no access to it's genetical code, let alone the ability to change it.

We didn't evolve from Chimpanzees, they are simply the closest relate living species to us. Both Humans and Chimpanzees shared a common ancestor about six million years ago. Both Humans and Chimpanzees evolved from that species.

You're right, that would be absurd. However, outside of the Soviet Union, that has nothing to do with evolution. Evolution is not a willful act, it is simply playing the odds. Cheetahs that are slightly faster are more likely to produce offspring than cheetahs that are slightly slower. Over generations this makes the genes for the faster cheetah to be more common, eventually to the elimination of the slower cheetah genes.

Evolving stopped and revolving started. You can tell everyone you heard it here first. :)

If this is trolling, you got me, but seriously?
This tells me you just don't understand how evolution works.

Its called adaptation, your genetics make changes to best suit your enviroment without your control, you don't get a say so, am I right?

No, you're not right. You are stuck with the genetics you're born with.
Imagine a bunch of chameleons.
Some have a long tongue gene A and some a short tongue gene B, some have independent eye gene X and some have eyes that aren't independent gene Y. So, you have AX, AY, BX and BY chameleons.
When they reproduce each passes on their genes, for example a AX mating with a BX will produce offspring that are either AX or BX, both parents providing the X and the offspring having a 50/50 chance of getting a long or short tongue, A or B gene.
The ones with A and X genes have a competitive advantage as they are better hunters than the ones with B and Y. Because they are better hunters they are more likely to live to produce offspring and thus more likely to pass their genes on to the next generation. The chameleons with AX really lucked out, they have both advantages and a higher percentage of them will live to pass on their genes than any other combination. The AY and BX chameleons don't have it all, but they each have a strength. The poor BY lizards are going to face an uphill battle though, and some will win it, but a higher percentage of them will fail and die without reproducing than the other combinations.
Gradually, over many generations, the B and Y genes will disappear from the gene pool due to this natural selection. No matter how hard the poor BY chameleons try or how much they need them to survive, they will never have long tongues or independent eyes.

I should really pay more attention in Biology, then again its 1 in the morning, my brain is fried and in weekend mode

A lot of people confuse the concepts of natural selection and evolution, using them interchangeably. Karnak explained it pretty well, but organisms have no choice in evolution, they are simply subject to nature's mutations.
No doubt humans have more impact on environment than they used to, and natural selection isn't as obvious, but it still exists. The impact humans have on their own natural selection has changed, but relative to how long evolution works, it's been a pretty small time.

That's the whole key right there. It's only been a couple hundred of years since mankind has reached the "industrial" era.. however evolution takes place over millions of years. Simply put we just can't imagine a time span long enough to explain how evolution works which is a big reason people often have trouble truly understanding it.
My biggest issue is that we allow (and in some cases encourage) weaker traits to thrive but still.. mother nature has a way of correcting things. We just may not like how she does it...
