Answer:
Wheat was first domesticated in Mesopotamia because of a favorable climate and a great diversity of wild grains that led to crossbreeding of seeds.
Explanation:
Mesopotamia ( Western Asia )was the first place of domestication of wheat. The favourable climate of intense sunshine of old Western Asia-kuwait, Iraq,...) favours photosynthesis which ensure food production,
Besides the population of this region with wide grains, on hilly land, ensured cross pollination of these wide seeds grains with wheat varieties leading to hybridization, and selection by natural selection for domestication and eventual evolution.
