# Horizontal Gene Transfer in C. elegans: A Key Mechanism in Evolution and Genetics ## Introduction to Horizontal Gene Transfer (HGT) Horizontal gene transfer (HGT)—the acquisition of genetic material from organisms other than direct descent—plays a crucial role in shaping the genetic diversity of life across domains, from bacteria to plants and animals. While HGT is most commonly associated with prokaryotes, recent research has illuminated its surprising significance in eukaryotes, including nematodes. One model organism central to this emerging understanding is Caenorhabditis elegans, a tiny soil-dwelling worm widely used in genetic and evolutionary studies. In this article, we explore horizontal gene transfer in C. elegans, examining its biological mechanisms, evolutionary implications, and potential applications in molecular biology and biotechnology.
