- Natural selection: Individuals with advantageous traits are more likely to survive and reproduce, passing on these beneficial traits to the next generation.
- Genetic drift: Random changes in gene frequency within a population can occur due to chance events, such as a small group of individuals establishing a new population.
- Gene flow: The movement of genes between populations through migration can introduce new genetic variation or homogenize gene pools among different populations.
- Mutation: Random changes in DNA sequences can create new alleles, introducing genetic diversity into a population's gene pool.

What are the four forces of biological evolution?
The four forces of biological evolution are mutation, gene flow, genetic drift, and natural selection. Mutation introduces new genetic variations, gene flow allows the exchange of genes between populations, genetic drift is the random change in gene frequencies within a population, and natural selection favors individuals with traits that increase their chances of survival and reproduction.
What is the modern definition of evolution based on population genetics?
The modern definition of evolution works at the level of genes, phenotypes and populations whereas Darwinism was mainly concerned with organisms, speciation and individuals. According to the modern definition of evolution, the populations evolve by changes in gene frequency brought about by random genetic drift, gene flow and natural selection. This change is gradual.
What is the genetic definition of evolution?
Evolution is the change in heritable characteristics of biological populations over successive generations. This change occurs due to genetic variation, natural selection, genetic drift, and gene flow.
What is caused by gene flow?
When genes are exchanged due to the mixing of populations, the result is gene flow. Genetic drift, along with natural selection, mutation, and migration, is one of the basic mechanisms of evolution.
What is evolution and what does it involve?
Evolution is the change in allele frequency over time in a population of organisms; change over time. This is all that it involves and whether the driver of evolution is natural selection, the adaptive driver of evolution, genetic drift, a random process or gene flow between populations, gene frequencies in these populations change and that is all evolution involves. Now, how evolution occurs with it's various drivers is another question for another time.
What hsa to change from generation to generation in an evolving population?
The frequency of the populations alleles. Their gene frequency must change to have evolution.
How is evolution different in small populations?
isolated gene pools

What are the four stages of evolution?
The four stages of evolution are mutation, natural selection, genetic drift, and gene flow. Mutation introduces new genetic variation, natural selection acts on that variation to favor traits that increase an organism's fitness, genetic drift refers to random changes in gene frequencies within a population, and gene flow is the transfer of genetic material between different populations.
How does gene flow lead to evolution?
Gene flow, or the movement of genes between populations, can introduce new genetic variation into a population. This can increase genetic diversity and lead to the spread of beneficial traits, which can drive evolutionary changes within a population over time. In essence, gene flow promotes adaptation and can result in the evolution of populations.
What is the role of gene flow in evolution?
Gene flow is the movement of genes between populations, which can introduce new genetic variations and prevent populations from diverging into separate species. It can increase genetic diversity, reduce differences between populations, and potentially lead to the spread of beneficial traits throughout a species. Gene flow is important in evolution as it promotes genetic exchange and maintains the genetic cohesion of a species.
What is the process by which change over time?
Evolution
How can a change in the gene pools evolution?
Not sure what you are asking, but, evolution is the change in allele frequency over time in a population of organisms.
