Mastering Natural Selection

The first step of natural selection is that organisms produce a far greater number of progeny than ever give rise to mature individuals. This means that there is a high mortality rate, as not all individuals will survive to maturity. This is significant because it creates competition for survival among the individuals.

The second step of natural selection states that the number of individuals in a species remains more or less constant. This is important because it means that the population size is stable, allowing for a consistent level of competition and selection for survival.

The third step of natural selection is that individuals in a species show variations in their characteristics. This variation is important because it allows for some individuals to be better adapted to the conditions of the environment, giving them an advantage in the competition for survival.

The fourth step of natural selection is that parents for the next generation will be selected from those members of the species better adapted to the conditions of the environment. This is significant because it ensures that the traits that contribute to better adaptation are passed on to the next generation, increasing the overall fitness of the population.

The fifth step of natural selection is that hereditary resemblance between parents and offspring is a fact. This means that subsequent generations will maintain and improve on the degree of adaptation of their parents, through gradual change. This contributes to the process of natural selection by allowing for the accumulation of beneficial traits over time.
