Animal domestication was crucial to increasing crop yields and thus allowing for economic specialization. What do all the primitive peoples have in common? They never developed work animals, in many cases no native species were able to be domesticated. 99% of the reason Europeans overran the Americas was having animals for transportation, farming, and to develop disease immunity.
Not only did that enable people who were born with bad eyes to see, but they made it possible to see far beyond age 30 or so when most people suffer a degradation of sight.
