Your weirdness with milk stems from it being from a mammal and you seeing more similarity with a mammal. But the underlying processes are equally estranged from the perceived natural way. and for the natural way again the definition remains difficult, because humans 50, 100, 500, 1000, 5000, 10.000 and 50.000 years ago all had very different lifes in which very different things happened.
What you described with artifical hormones is something of the past 50 years. But what about the other 6.000 years of humans drinking milk already? What you describe isnt specific to milk.It is specific to modern industrialized countries.
The original weirdness comes from thousands of years that humans saw these other animals with their animal boobs dripping milk into the mouths of their babies, and decided that we need some of that non-essential nourishment at any cost.
Thatโs why itโs weird. And it only gets weirder when we have to build up industrialized processes to support an obviously unsustainable and harmful process becauseโฆthe percentage of the population who can stomach the non-essential infant cow juice want it so badly?
That weirdness has been happening as long as weโve been stealing milk from cow babies.
and decided that we need some of that non-essential nourishment at any cost.
But it was essential. Drinking cow milk was such an evolutionary edge that genetic analysis indicated every lactose tolerant person to have the same ancestor where it first occured some 6.000 years ago.
Drinking milk was not essential, as evidenced by your very mention of people being lactose intolerant to milk, a simple fact that proves milk is not essential.
