Question 18

The size of a plant's seeds reflects an evolutionary trade-off.Large,heavy seeds contain ample nutrient reserves to fuel seedling growth but may not travel far.Small seeds,on the other hand,store limited nutrients but tend to disperse far and wide.The crops that humans cultivate typically have larger seeds than do their wild ancestors.How has human farming altered the evolution of these crops?
