The Evolution of Complex Organs

The video explains Darwin's theory of evolution by natural selection, focusing on how complex organs like the eye and wings evolved from simpler forms. It highlights the role of genetic variation and natural selection in producing incremental improvements over time. The evolution of the eye is detailed through various stages, from simple light-sensitive spots to complex structures like the human eye. The video also discusses the independent evolution of flight in insects, birds, and bats, emphasizing the vast time span of 3.5 billion years that allowed for such complex developments.
