Episode notes
Active Mechanism Versus Passive Machine Model
- Two competing models framed early biology: passive designed machines versus active self-making organisms.
- Jessica Riskin traced this active mechanist tradition from 17th-century automata to Lamarck's championing of organisms' creative agency.
Darwin Was Partly Lamarckian
- Darwin incorporated both Paley-like design reasoning and Lamarckian inheritance of acquired characteristics.
- Charles Darwin explicitly accepted 'inherited effects of use and disuse' alongside natural selection in his writings.
Lamarck The Taxonomist And Professor Of Insects And Worms
- Lamarck rose from a poor noble family, avoided the priesthood, served as a soldier, then became a botanist and taxonomist in Paris.
- He named over 6,000 species, categorized clouds, and later became professor of "insects and worms," coining "invertebrate."
