Its almost certainly instinctual, humans along with other great apes (any many other animals) show a preference for cooked foods over raw in testing, the number that prefer it increases drastically if they are have sampled cooked foods before. So it is likely as built in as your desire for sweets and salt.
Just becasue something is instinctual does not mean ...

Its actually much simpler than you are making it out to be, carrying capacity is not an issue, humans long since surpassed the planets carrying capacity without advanced technology. The real factor is infant mortality.
consider both K and r strategies
Say you have two sets of parents each starting with the same amount of resources. In r strategy the approach ...

The most definitive conclusions about the common ancestor are made by comparing genetic sequences of the organisms, for which well developed mathematical/computational methods exist, see, e.g., Inferring Phylogenies or An introduction to molecular evolution and phylogenetics.
For distant species the genomes are rarely directly comparable, so that some ...

TLDR
Sympatric speciation and allopatric speciation with later migration into the same habitat were historically diffucult to distinguish without looking at palaeo-biological data. The paper argues that while palaeo-genetics has made this easier, it is still difficult to distinguish pure sympatric speciation (which it calls primary) and sympatric speciation ...

Humans are incredibly good at processing maillard compounds, which include both beneficial and mildly toxic byproducts of cooking. Humans are better at breaking them down than other animals. This is presumed to be an adaptation to eating cooked food. Malliard reactions are also a good indicator of when most plant and animal products are safest to eat via ...

The other answers have done excellent job explaining how the stoned ape theory contradicts the Darwin's own theory of human origins. What remained unmentioned is that Darwinism have been the basis of the modern evolutionary theories for more than a century, and in this modern light there are even more glaring contradictions between the McKenna's theory and ...
