How do you explain natural selection?
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
What is the Malthusian population theory?
Thomas Malthus was an 18th-century British philosopher and economist noted for the Malthusian growth model, an exponential formula used to project population growth. The theory states that food production will not be able to keep up with growth in the human population, resulting in disease, famine, war, and calamity.
What did Darwin learn from Malthus?
Malthus’ work made Darwin realize the importance of overpopulation and how it was necessary to have variability in different populations. Darwin also used Malthus’ ideas to use competition as well as the survival in numbers idea to come up with his full idea of natural selection.
