History

Which outcome occurred when early Andean cultures exceeded terraced field capacity?

A)Decreased maize genetic variability
B)Enhanced potato crop diversification
C)Increased native llama populations
D)Improved grain storage techniques

💡 Explanation

Exceeding terrace supportable capacity amplified inbreeding depression in mass-planted maize, because genetic bottlenecking reduced allele diversity impacting yields. Therefore, the population’s narrowing gene pool became increasingly vulnerable, rather than showing improvements via traditional methods.
