The three conditions that must be met for evolution to occur by natural selection are that there must be variation, there must be selection, and there must be inheritance of variation. C. Some organisms may be very closely related, even though a minor genetic change caused a major morphological difference to make them look quite different. Proponents of the adaptation argument argue that individuals adjust and adapt to new situations and conditions, while opponents argue that the population as a whole adapts, which can lead to unforeseen consequences.

How does genetic variation help a population survive in the face of changing, uncertain environments? Olfspring must be similar to their parents due to shared genes. 1. Evolutionary biologists often compare the morphological features of different organisms to look for relationships to determine how they have changed over time. Explain why only populations evolve but individuals do not. The genotype that an individual possesses for a trait, in turn, determines the phenotype the observable characteristicssuch as whether that individual actually ends up with straight, wavy, or curly hair.
