If humans evolved from Mesoamerica and spread throughout the world (via the Bering Strait in order to reach Eurasia) animal domestication and the rate at which societies developed would be slower than how they actually happen.
In Mesoamerica and throughout the Americas there were many candidates for animal domestication “but most of America’s big wild mammals (including its horses, most of its camels, and other species likely to have been domesticated had they survived) became extinct about 13,000 years ago” (pg. 162). Most of these big animals died at the end of the last Ice Age which leaves a few amount of animals with the chance of domestication. Out of the few candidates left in the Americas, only a very small amount of those were domesticated. The llama and the alpaca (members of the Ancient Fourteen) were domesticated in the Andes, and the dog was domesticated in North America. Societies in the Americas would develop, but they would develop at a slow rate because of the lack of domesticated animals.
If humans evolved and spread from Mesoamerica, they would be surprised at the amount of food (the Fertile Crescent) and the amount of animals (the rest of the Ancient Fourteen) that could be domesticated in Eurasia and northern Africa. The process of domesticating these plants and animals will be slow because these humans need some time to adapt, but there would be a much higher possibility of developing large societies because there is much more plants and animals.
The differences with these societies compared to the ones that actually developed in history is the speed in which they developed because they were developed from different origins.
