Well a lot of people have been telling me evolution is real. They give me the most craziest surreal 'facts'. Has anyone discovered any fish with legs? Any humans with gills or fins? If you put all the pieces of a watch into you're pocket and shake it around for trillions of years, will it ever become a watch? Is there but one possibility? Or if you completely dismantle a chicken and a fish, and put it into a box, shaking it around for trillions of years. Will it ever become a fish with wings? or a chicken with fins? :l
You're presuming the subject would survive long enough. Go above 24,000 feet and not only would digesting your food become near impossible, sleeping would be effected and that is before you get to breathing difficulty.
Go about 26,000 feet and the body will use up more oxygen than it can reasonably replace, so no amount of training will allow to survive for long at that altitude.
We can only adapt so far before the body won't go any further. You have to survive to evolve.
Please keep in mind mutation is not THE driving force behind evolution, not only; mutation/selection (natural, sexual)/migration/genetic drift all have their impact...
For instance if you had a child, that child will on average have about 150 mutations in his genome. However it's unlikely any of them will significantly effect his ability to survive.
So, that would apply to me? I likely have around 150 mutations in my genome? Can you provide sources backing this up?
what beneficial mutations. there is no such thing.
(macfan1) left this thread a long time ago, but I didn't see anyone answer this and it bugged me.
Sickle cell makes you less likely to catch malaria, since it makes your blood cells smaller and an odd shape, so the mosquitoes are less likely to bite you, because that will mean less blood and we all know just how badly that mosquitoes want to become little insect-like vampires. So in Africa (since it's more likely to occur in Africans) this is a plus because those that don't have sickle cell will be more likely to be bit by the tiny vermin. Sickle cell is a mutation that is beneficial to people in Africa due to malaria carried by mosquitoes.
