You adapt to survive right? Or did our DNA evolve in such a way to just allow us to breed. Did it know we would be ok long enough to reproduce?

No. Random mutations occur which may or may not be advantageous. If they are advantageous the animal has a better chance to survive to pass that mutation on to its offspring. If they are not advantageous (or harmful) there is no improved chance (or even a reduced chance) to reproduce.


As for arthritis some forms are hereditary.
Exactly. And since it usually appears well after offspring have been produced it has nothing to do with evolution.




Just did a little research on skin cancer and I think you sufficiently answered my question.

Wow that actually makes perfect sense. What's your take on us shedding our primate fur? Also most skin cancer isn't hereditary.

Yes. Darwin thought it made sense too.

There's the "aquatic ape" theory (not that great).
But being hairless in the savanna could have been a beneficial adaptation, aiding the shedding of body heat.

Well being a marine you know that naked skin in the heat is not your friend. Wet sweaty fur would cool the body better then naked skin.

I do better on a hot day than my golden retriever does. Especially in the shade.
Of course I did replace my fur with sweat glands. Maybe that has something to do with it.

Idk but I'm sure apes sweat like man. In extreme heat your sweat don't stay on the body long enough to cool your core temp. The lack of sweat is one of the man reasons people become victims of heat stroke. Imo it don't sound like a beneficial adaptation.

After giving it some thought if we evoled in africa like we are tauggt then maybe the humidity was enough to keep us cool. Since its not dry heat.

That would depend on the humidity. Interesting thing though, the faster sweat evaporates, the more it cools you. You know "It's not the heat, it's the humidity." You don't get really sweaty in Tucson because it evaporates so fast.

Yes. Being dehydrated (which leads to less perspiration) is a bad thing. Having fur doesn't really help with dehydration though.



Imo it don't sound like a beneficial adaptation.
Yeah, well. There are a few things I would have done differently given the chance.

Just out of curiosity, name one thing you would have done different.

I must be missing a key point, but when I read things like that I just get so sad.

The implications that the little knoweldge known is so little it will be lost before the next generation.

Back to banging sticks on rocks and calling for sky gods to make it rain...

Because we age...

Also because of prior health conditions.
