@puttingj1 Tell your teacher that the best current evidence does not support the hypothesis of long necks evolving for food only, but instead evolved as a mechanism for males fighting for mate choice and for food. Because the genes that regulate the formation and growth of the spine and related organ systems is so fundamental, the changes have to be present in females as well as males.
