Alfred Russel Wallace's Contribution to the Theory of Evolution

The video discusses Alfred Russel Wallace's contributions to the theory of evolution, highlighting his independent proposal of natural selection alongside Darwin. Wallace is credited with discovering the use of color in plants and animals to deter predators, a trait evolved through natural selection. The video also explains speciation, where populations of a species become so different due to geographic isolation that they can no longer interbreed, leading to the formation of new species.
