Charles Darwin's life and work, from his birth in Shrewsbury to the publication of 'On the Origin of Species' and beyond, revolutionized biology with the theory of evolution by natural selection.

Darwin opens his first notebook on the 'transmutation of species,' starting to develop his theory of evolution. #evolution #science
Darwin reads Thomas Malthus's 'An Essay on the Principle of Population,' which gives him the idea of natural selection as a mechanism for evolution. #evolution #science
