Molecular drive

Molecular drive is a process where groups of genes and DNA sequences are transferred directly between different populations or species, often through mechanisms like hybridization or gene flow. This transfer allows genomes to evolve independently of traditional natural selection or mutation. Essentially, it acts like a genetic "shuttle," spreading specific gene combinations across populations, leading to genetic diversity and variation within and between species. It helps explain how complex traits and genetic patterns can emerge rapidly and why some species share similar genes despite being separate biologically.
