Detailed explanation-1: -The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Detailed explanation-2: -The theory of evolution through natural selection was independently developed by two British naturalists – Charles Darwin and Alfred Russel Wallace.
Detailed explanation-3: -Which of the following observations and inferences led Charles Darwin to his theory of natural selection as a mechanism for evolution? Individuals in a population of any species vary in many heritable traits.
Detailed explanation-4: -Darwin’s theory of evolution by natural selection states that living things with beneficial traits produce more offspring than others do. This produces changes in the traits of living things over time. During his voyage on the Beagle, Darwin made many observations that helped him develop his theory of evolution.
