Darwin's Role In Influencing Natural Selection

Natural selection was a fundamental idea formed by Darwin that living things evolve gradually from generation to generation. Darwin argues that all living species come to historical process through a historical process involving random changes. Through natural selection living things have acquired to behave in ways that provide the promotion of survival and reproduction. What happens in natural selection is that the organisms with favorable traits that help them survive live long enough to pass their traits down through offspring. All the good traits passed down to the next generation help them. It would bring certain behaviors that are crucial for survival. The traits, if passed down for long enough, can affect the whole species, and eventually, the whole species can have that trait like the behavior because they affect fitness and survival chances depending on their react to stimuli.
Firstly he says there's overproduction of offsprings in each generation than they have a chance of survival. Secondly he mentioned that there's is variations in the people in each generation not every generation necessarily looks the same. Third, these individual differences are inherited and passed on from one generation to another. Finally the last one that plays a role in influencing natural selection is the environment. People who have certain traits are more apt to fit that particular local environment and survive to produce offsprings than those individuals that don't. Genetic information best determines behavior when a species environment varies little from generation to generation. Genes also create the learning, memory, and cognition, mechanisms that allow animals to acquire and store information about their environment for use in shaping their behavior. Environmental effects help to turn genes on and off resulting in bodily changes that change the individual's
