Detailed explanation-1: -Individuals with adaptive traits-traits that give them some advantage-are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Over time, these advantageous traits become more common in the population.
Detailed explanation-2: -The survival of the fittest theory was put forward by Charles Darwin and he suggested that the organisms best adapted to the environment are more likely to survive and reproduce. Natural selection: It is a key feature of evolution that was proposed by Charles Darwin.
Detailed explanation-3: -Darwin argued that, as a consequence of natural selection preferentially retaining those heritable variations associated with greater survival and reproductive success, organisms will appear as if they are designed to maximize their survival and reproductive success-that is, their Darwinian fitness.
