I'm just a bit confused by the notion of "target food", because in evolution things develop in symbiosis, and it's not a deliberate race to any
If one looks at milk, one can say it is an imperfect food for humans, but domesticating cattle provided many benefits.
If one looks at Africa, herders had a distinct advantage over hunter-gatherers.
Keeping cattle, goats and sheep allowed large groups of herders to suddenly expand into areas that were rather arid, and they quickly overcame the
The irony is that many cattle-raising Africans are lactose-intolerant, which means their use of milk and cattle is not that ancient.
In SA they overcome this by allowing the milk to sour and ferment to a degree.
Cattle also provided dung for housing and fuel, and for agriculturists, fertilization.
Cow urine was used medicinally wherever their were herding people.
They also provided meat and blood (many tribes mix cow blood with milk).
To the Cape Khoi their oxen were like horses, and they rode them, and drove them into battle.
They could control entire herds like regiments with whistles.
Clearly they opened up forests and bushland for human occupation and game, and when Europeans found the "African savannah", that was a carefully
Only now are some researchers realizing that banning herders from game reserves was a big mistake, because they created that landscape.
The herders became taller and stronger than the hunter-gathers, and although the San (Bushmen hunter-gatherers) are famed for reaching astounding
longevity, the herding people of the Hamitic variety (the Masai, for example) are famed for their stature.
Living with livestock is a mixed blessing.
Humans got many diseases from their cattle, especially in Europe where peasants and their animals shared houses in winter.
But Europeans also developed some resistance to those diseases, like smallpox.
When they colonized other countries the natives died very quickly from such diseases, because they had developed no immunity whatsoever.
But saying evolution makes a target food or plant, and them some species develops to eat it is unsound.
That's like saying evolution makes a virus and waits for some species to get it.
Humans were food once, and we had to adapt from a variety of ape pretty fast, but that change in environment made us come down from the trees, and
although we barely made it at times, it was our brains that grew larger.
