Wheat is a group of grass species. Cultivation originated in the eastern Mediterranean about 10,000 years ago; wheat is now grown on more land area than any other commercial food
If humans did not exist, what would have been the likely evolutionary trajectory of wheat? How could you test this hypothesis? A. Wheat would be a wild grass found only in its native environment. Colonize different environments and measure the establishment success of wheat. B. Wheat would have become a dominant grass on the planet regardless of the presence of humans. Plant wheat in an area and measure its growth rate. C. Wheat would have gone extinct because few species have survived over 10,000 years. Plant wheat and other grasses and watch the resulting ecosystem develop. D. Wheat would have spread beyond its original ecosystem to other hospitable environments. Examine the dispersal and colonization of other grass species with similar characteristics to wheat.
