Darwin's Theory and Evolutionary Concepts

The video explores the contributions of Charles Darwin and Alfred Russel Wallace to the theory of evolution by natural selection. It discusses the shift from natural theology to scientific inquiry, Darwin's voyage on the HMS Beagle, and the development of his theory. Wallace's independent discovery of natural selection and his work in biogeography are highlighted. The video also covers the publication of 'On the Origin of Species' and its impact, as well as the public reception and misinterpretation of Darwinism.
