So a lack of animal husbandry is the same as lower technology and a lack of farming.
replyI never understand the “lack of animals to domesticate” angle. They did domesticate animals, such as the llama and alpaca.
replyMore could have been domesticated and presumably would have been if the had more time to advance. It’s a shame giant sloths were killed off…
Cattle, oxen, horses, camels, mules, donkeys, etc. The animals that are capable of heavy labor at or exceeding human level weren't present in the Americas. Llama and alpaca are more useful for fiber and meat than labor. Buffalo might possibly be useful but they are too big, wide-ranging, and aggressive to be easily tamed and bred.
replyRemember chicken and pigs, too. Not useful for labour, but good sources of high value nutrition, and can be fed of scraps or whatever they find around the house and garden.
replyIn Europe, pigs like eating acorns, which are otherwise fairly useless to humans.
