- We don't fertilize native vegatation, why is it necessary to fertilize agricultural crops?Many plants and insects that pollutes them are clear examples of Co evolution? True or FalseHumans have been selectively breeding corn for generations. During the process of domestication, the wild form of corn was eventually changed into a form that has more favorable traits. Early farmers most likely used corn seed that had – thin stalks to withstand stronger wind. a darker color so that they would blend with the field and be protected from predators. larger leaves that could be used for compost. the ability to grow in a large number of climates, soil types, and produced the largest amount of kernels

Which of the following statements best describes the evolutionary concept illustrated by this example? A. Homozygous genotypes increase fitness in a population. B. Hybrid plants are known to have a disadvantage over homozygous genotypes. C. Natural selection selects against the recessive gene and for the dominant gene. D. Certain phenotypic variations can significantly increase fitness of the organism in particular environments.Geographer, historian, and author Jared Diamond (1987) once referred to agriculture as "the worst mistake in the history of the human race." Given what you have learned about the health consequences of the domestication of plants and animals for humans, how would you respond to his statement?
