Web20 de ago. de 2024 · A recent experiment in a natural setting shows that selection acts on behavior and morphology, but acts on each trait independently of the other. Behavior, like morphology, can vary among individuals, be heritable, contribute to fitness, and hence be subject to evolution by natural selection. For a long time, however, behavior has … WebTwo modes of selection: individual selection opposes altruism; selection among kin groups favors altruism. Classic examples: helpers at the nest in birds. Young offspring remain at the nest to help their parents produce more siblings in subsequent years/seasons.
