Are human bodies evolved to this point still for hunter and gathering?

Is it evolutionary designed up until this point that our bodies are meant for hunting and gathering instead of office jobs and using technology, our bodies are not evolutionary design for that currently and we are still evolutionary designed to perform hunter gathering tasks.

What is our current bodies designed for by evolution currently?

    When the ape ancestors of humans first started occupying the African savanna, their bodies were not suitable for bipedalism. Nevertheless, even though their body had evolved to walk on 4 legs, they started walking on 2 legs anyway because they cannot keep walking on 4 legs and hope that somehow, hopefully soon, that their bodies will evolve to be suitable for 2 legged walking and running before they start doing it. That is not how evolution works.

    Scientists point out that behavior often drives evolution. That means many organisms first adapt to their surroundings by changing their behavior (if possible of course). Adaptations come later. Because our ancestors were already walking on 2 legs, any mutation that happens to allow them to walk on 2 legs better than before will be adaptive and such mutations would then be favored by natural selection. Instead of being eliminated, these mutations will actually increase in frequency until that entire population or species have them. Any individual that does not have the mutation may not run as fast or as well as others and they or their descendants therefore would likely be eliminated by natural selection over many generations.

    The same is true for adaptations that help humans become hunter gatherers. Our ape ancestors did not hunt, although our closest relatives, the chimp, do hunt. They nevertheless hunt in a different way than humans do. Humans use bows, arrows, stone axes and spears to hunt. Chimps do not. Humans evolved to throw the javelin/spear, but chimps cannot do the same. once again, humans were hunting before their bodies became adapted for hunting. Because we can still throw the javelin and shoot bows and arrows, our bodies are still adapted for hunting. However, since the invention of agriculture, many people no longer have to hunt. That means traits that allow us to hunt are no longer being used. As Darwin points out, when a trait is not used, it tends to be more variable, including being lost. That means many of us are not any good at throwing spears or hunting with bows and arrows, because we won't starve to death even though we no longer can hunt well.

    Humans now live in an industrial society and many of us do desk jobs. So currently many people have to become educated to survive. Since education requires the ability to read and write and to comprehend and apply what we are taught, we are putting selective pressure on the ability to learn. Nevertheless, because of the social safety net and also job openings for the less well educated, fewer people who are not intelligent enough will be eliminated by natural selection, compared to earlier periods in our history.

    We evolved as hunter-gatherers. Omnivorous with high intelligence such that we could adapt to unusual circumstances by using tools. Evolution works such that we are good enough to survive and reproduce, but that doesnt mean we are optimized.

    So, I think it would be fair to say like many of the lesser animals, we can live in many environments to include urban ones and more natural ones. Clearly, we do better in man made environments based on our hugely expanding populations and the increasing life span of our species.

    More or less. Depends how you’re built. But yes. They human body isn’t meant to just sit around.

    We were suited to h & g half a million years ago. Society, cuture and innovation have removed the need to hunt and gather. We can still live that way.

    No , I believe humans evolved to opportunistic scavengers and adopted hunting and gathering to support a larger population, just as they adopted farming to support the larger populations once hunting and gathering would not all the hunger mouths they had to fill.
