His work convinced Darwin that organisms overpopulate and compete for resources.

Detailed explanation-1: -Lyell’s book contributed to Darwin’s Theory of Evolution by convincing Darwin that. natural selection was responsible for the acquisition of new traits within a population when there was competition between species.
Detailed explanation-2: -Lyell argued that the formation of Earth’s crust took place through countless small changes occurring over vast periods of time, all according to known natural laws. His “uniformitarian” proposal was that the forces molding the planet today have operated continuously throughout its history.
Detailed explanation-3: -Darwin took Lyell’s book, Principles of Geology, with him on the Beagle. In the book, Lyell argued that gradual geological processes have gradually shaped Earth’s surface. From this, Lyell inferred that Earth must be far older than most people believed.
Detailed explanation-4: -The answer choice that best describes the theory of natural selection is D) Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.
Detailed explanation-5: -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.
