Theories of Evolution

The video tutorial explores the concept of evolution in biological populations, focusing on key theories such as Lamarckism, Darwinism, and mutation theory. Lamarckism, proposed by Jean-Baptiste de Lamarck, suggests that acquired characteristics can be inherited. Darwinism, developed by Charles Darwin, emphasizes natural selection and survival of the fittest. Darwin's observations of Galapagos finches led to the idea of descent with modification. The video also discusses the mutation theory by Hugo de Vries, which posits that new species arise from sudden mutations. The tutorial highlights the importance of variations in evolution and the role of natural selection in shaping species.
