Dr. Lahtinen and her colleagues take competitors out of the equation. In winter, ice age people would have needed to forego vegetation, relying on looking. However folks can’t survive on protein alone. Ultimately they starve or get protein poisoning. They want fats, so they might have eaten primarily the fatty components of prey, with some lean meat left over. Wolves, with completely different digestive methods, can stay for fairly some time on pure protein.
The researchers say of their paper that amongst human Arctic hunters, animal protein might have supplied as much as 45 p.c of the energy wanted within the winter. In addition they calculated the quantity of protein within the prey out there to wolves within the ice age, exhibiting that they’ve protein “over the boundaries that people can devour.” Individuals and wolves hunt comparable species, so if people have been consuming the identical animals they might have extra protein from their kills.
People, together with trendy hunter-gatherers, have an odd behavior of feeding different animals and maintaining them, at the very least for some time. So the authors lean towards the concept of varied human bands sometimes snatching a wolf pet. Ultimately, the 2 species grew nearer collectively and the brand new dog-wolves turned helpful. Many hundreds of years later, now we have pandemic puppies.
The speculation is simply that, an concept about what may need occurred, not an illustration of what did occur. However Naomi Sykes, a zoo-archaeologist on the College of Exeter in Britain, who reviewed the paper for publication, stated she thought the researchers made two necessary factors. “The primary is their suggestion that there would have been minimal dietary competitors between people and wolves.” The second, she stated, was that their speculation “flips the concept of domestication” to folks feeding animals reasonably than elevating them to eat.
She stated archaeological finds point out that the domestication of chickens, rabbits, horses and different animals might have begun with the animals being intentionally fed. In a few of the earliest discoveries, she stated, the traditional bones present that the animals have been “being maintained, taken care of and even worshiped reasonably than eaten.”
