Nematode evolution

Nematode evolution involves gradual changes in their genetic makeup over millions of years, allowing them to adapt to diverse environments. Originating around 500 million years ago, nematodes have diversified into many species, some parasitic and others free-living. Their simple, flexible body plan and genetic adaptability have helped them survive extreme conditions and exploit various ecological niches. Evolutionary processes like mutation, natural selection, and gene flow have shaped their functions and behaviors. Overall, nematodes exemplify how small, adaptable organisms can evolve complex survival strategies over vast periods, contributing significantly to ecosystems worldwide.
