Being better cooks causes evolution?Probably improvements in cooking made them increasingly redundant
A lack of good dentists cause evolution?. . . a lack of dental treatments and their propensity for infection/malformation make them an increasing liability.
Being better cooks causes evolution?

I have no idea??? I wasn't the one that said that being a better cook causes evolution to happen. . .You have no idea what evolution is. It is not caused by those factors, it is guided. Learn the difference. Or, even better, learn what evolution is.
Yes, you have no idea! You. Have. No. Idea!I have no idea???
No one said that.I wasn't the one that said that being a better cook causes evolution to happen. . .

Original Question said:What advantage do smaller jawed humans with no wisdom teeth have over larger jawed humans with wisdom teeth do you reckon?
Advantageous traits only establish themselves if they offer a reproductive advantage. If the members of a population with the advantageous trait reproduce more successfully, i.e. if they produce more children than the members without the advantageous trait, the trait will be established. If they don't, for whatever reason, it won't.OK, in an effort to learn, please help me with this:
So cooking eliminated a reproductive advantage that humans with wisdom teeth had. Is that the same as saying that cooking food causes evolution?In short, the reproductive advantage stemming from having larger teeth vanished with the advent of cooking.
No, because evolution always happens when an imperfect reproduction of genes occurs, i.e. every generation. The advent of cooking did not cause evolution, unless you specifically talk about the evolution of the human teeth, in which case it may be valid.So cooking eliminated a reproductive advantage that humans with wisdom teeth had.

So, we had a full mouth of teeth. Then someone had a mutation that caused them to be sans at least one wisdom tooth and maybe up to four. There was no reproductive or survivability issue. So, through the generations, the frequency of missing wisdom teeth has increased.No, because evolution always happens when an imperfect reproduction of genes occurs, i.e. every generation.
Since we are, then cooking food may be a valid cause of evolution.The advent of cooking did not cause evolution, unless you specifically talk about the evolution of the human teeth, in which case it may be valid.

Well, in this context, yes. Yes, it's a valid cause for the evolution of missing wisdom teeth.Since we are, then cooking food may be a valid cause of evolution.
These two reasons are not exclusive. The invention of cooking was not the reason why humans were born without wisdom teeth, but it's the reason why this trait stayed.The cooking of food seems a little 'far fetched' as to be the reason that we started showing up without wisdom teeth, but I'll accept it. A reproductive mistake that left someone without wisdom teeth seems a lot stronger of an explanation.
This could very well have been the case. Mutations are the cause of new traits, but selection decides which traits are going to stay.Why wouldn't missing wisdom teeth be the result of an allele variation/supression?
I think so, yes.(I hope I used 'allele' in the right context).

Are humans evolving?

Are Humans Living Organisms?
What are the signs that humans are evolving into not humans?
This Forum is good evidence for evo...oh...I mean devolution!
Does evolution state that creatures get better through the process of adpating, mutating, evolving, changing?
