Welcome to corporate nonsense! Along with the tape fucking lines

Yes like I said not physical fitness but instead genetics , like as you said what happens when we breed. And yes sometimes as you said it's not always a good thing , which is where the adaptation becomes an advantage or disadvantage. Some were cut out to survive , some were not. All depends on the situation , like skin color and sun exposure. Some skin pigmentation works in some climates some better in others. You bring up concentrations of people overtaking areas and say the earth can sustain and to some part I agree but we can't spread out and inhabit every corner of land , not all of it is habitable. You must admit humans have made it through a lot and more than we even understand at this date , but they did it without all the fancy modern tech. Were all an example of what nature can provide over time and I'll take that over what we as humans can conjure. All in all humans have become arrogant as a species and that's not a trait that is desirable for future sustainability.

Environmental pressure like surviving disease? Pre vaccine. Some bodies can handle some can't. May not even come down to physical fitness but genetic makeup. Yes , lack of small pox... but at same time over population. Over population is bad , if you care to read up on it. You kinda side stepped the issue of human species sidestepping nature's checks and balances on species. Where does our evolution go from here once we've eliminated all environmental pressures? Do we then stagnate and become unable to survive?

Any idea on how or why those changes happened to cause said evolution?? Can you comment on the role diseases and viruses play? Evolution is just adaptation to your environment. Survival of the fittest , not survival of the over inoculated. Like nature has evolved to keep populations in check , we've side stepped that and look where that got us.
