Jan 29, 2021 at 18:14 comment added Roger V. I understand how greater resource access can be an advantage, but it doesn't mean that it always is. I am simply trying to help you clarify things. Your argument about humans being able to digest cooked food better is a solid one, but it needs to be correctly interpreted from the evolutionary standpoint.
Jan 29, 2021 at 17:28 comment added John @Vadim if you don't understand how greater resource access constitutes an advantage I can only suggest you ask a few questions about evolution. This is pretty basic evolutionary biology.. To use an very basic example, why do herbivores have longer guts than carnivores?
Jan 29, 2021 at 17:14 comment added Roger V. advantage in evolutionary terms means producing more offspring - either by living longer or by doing it more frequently or in bigger numbers. If Bob produces as many miserable Bobs as Jon happy Jons, neither has particular advantage.
Jan 29, 2021 at 16:36 comment added John @Vadim NO, incentive does not mean do it or die. incentive or in biological terms "advantage" comes from well having an advantage. If Jon is better at digesting cooked food that Bob he has a distinct advantage, he is getting more nutrients and fewer problems from the same foodstuffs. Cooking was a part of the hominid diet long before Homo sapien evolved. Also only one link refers to gut microbes, that is the one that lists many factors.
Jan 29, 2021 at 14:31 comment added Roger V. en.wikipedia.org/wiki/Adaptation What you are saying that people became better at digesting cooking food (adapted) without any insensitive to do so. What could be an adaptation is if people began using cooked food, because they are better at digesting it. Also, the link that you provided emphasizes the role of the gut mircobiome, which is in a big part acquired during lifetime (apart from what we get at the birth, which is still not genetic).
Jan 29, 2021 at 14:08 comment added John @Vadim no a trait to be better at doing something is also is also an adaptation. very few adaptations have lethal alternatives, they are just better than the alternative. humans are better at digesting cooked food than any animal tested, due to known unique enzymes, that is adaptation. onlinelibrary.wiley.com/doi/abs/10.1002/evan.21498
Jan 29, 2021 at 6:38 comment added Roger V. Adaptation implies selection. In other words, the claim is that those uncapable of digesting cooked food would have lesser chances of survival. On the other hand, more random drift is quite possible. A somewhat similar case is the increase of the number of women in need of cesarian section - it is not a adaptation to an evolutionary pressure, but result of removing such a pressure.
