Complex biological traits evolve from simpler ancestral life forms through natural selection and genetic drift
Complex biological traits evolve from simpler ancestral forms through mechanisms such as natural selection, genetic drift, and gene duplication, as supported by evolutionary biology.
The claim states that complex biological traits evolve from simpler ancestral life forms through natural selection and genetic drift. All relevant papers substantiate aspects of this fundamental evolutionary principle, demonstrating how genetic drift, natural selection, and mutation drive the evolution of complexity from simpler origins.
