What is Natural Selection?

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. This evolutionary mechanism explains the change in heritable traits of a population over generations.

Variation in natural selection

refers to the differences among individuals in a population that contribute to their success in surviving and reproducing in a given environment.

Inheritance

is the genetic transmission of traits from parents to offspring, influencing evolution by passing on beneficial adaptations.

Differential survival

is the concept that individuals with advantageous traits are more likely to survive and reproduce, leading to evolutionary changes in a population.

Sexual selection

is a mode of natural selection in which individuals with certain traits are more likely to secure mates and reproduce, thereby influencing the evolution of those traits in a population.

Gene flow

is the transfer of genetic material between populations, often occurring through migration, which can introduce new genetic variations and affect evolutionary processes.

Genetic Drift

is the random fluctuation of allele frequencies in a population due to chance events, which can lead to decreased genetic diversity and some alleles eventually becoming stabilized in populations
