Question

Quizplus · Accepted Answer

The physical characteristics of giraffes' long necks and woodpeckers' sharp beaks are adaptations, which are traits that have evolved in a species to improve its chances of survival and reproduction in its environment. These adaptations may be physical or behavioral and allow the species to better access food, avoid predators, or compete with others for resources. Fitness is a measure of how well an organism is adapted to its environment and how successful it is in reproducing, while natural selection is the process by which organisms with traits better suited to their environment are more likely to survive and pass on those traits to their offspring. Genotype refers to an organism's genetic makeup, including both inherited and acquired traits.
