Genetic admixture refers to the process where two or more previously isolated populations begin interbreeding, resulting in the exchange of genetic material and the formation of a new gene pool. This process is crucial for understanding human evolution, population genetics, and the genetic diversity observed in modern populations.

Isolated Populations

Interbreeding refers to the process where individuals from different species, subspecies, or genetic populations mate and produce offspring. This can lead to hybrid vigor or outbreeding depression, influencing biodiversity and evolutionary trajectories.

Human evolution is the lengthy process of change by which people originated from apelike ancestors, involving the development of traits such as bipedalism, larger brain size, and complex tool use over millions of years. This evolutionary journey is evidenced by fossil records, genetic studies, and comparative anatomy, providing insights into our biological and cultural origins.

Human Evolution

Population genetics is the study of genetic variation within populations and involves the examination of changes in gene frequencies under the influence of evolutionary processes such as natural selection, genetic drift, mutation, and gene flow. It provides a genetic basis for understanding evolutionary biology and helps explain patterns of diversity and adaptation in natural populations.

Population Genetics

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species, which is essential for populations to adapt to changing environments and ensures long-term survival. High genetic diversity increases a species' ability to withstand diseases and environmental changes, while low diversity can lead to inbreeding and increased vulnerability to extinction.
