Detailed explanation-1: -According to Charles Darwin’s theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

Detailed explanation-2: -Some variations make an individual better suited to survive and reproduce in their environment. If this continues over generations, these favorable adaptations (the heritable features that aid survival and reproduction) will become more and more common in the population.

Detailed explanation-3: -Based on these simple observations, Darwin concluded the following: In a population, some individuals will have inherited traits that help them survive and reproduce (given the conditions of the environment, such as the predators and food sources present).

Detailed explanation-4: -This variation means that some individuals have traits better suited to the environment than others. Individuals with adaptive traits-traits that give them some advantage-are more likely to survive and reproduce.

Detailed explanation-5: -Organisms can adapt to an environment in different ways. They can adapt biologically, meaning they alter body functions. An example of biological adaptation can be seen in the bodies of people living at high altitudes, such as Tibet.
