Join Skeptiko host Alex Tsakiris for an interview with author, historian and evolution theory expert, Professor Michael Flannery. Explain the differences between Darwin’s view of competition and Wallace’s view of competition? Professor Flannery: Wallace tended to view competition occurring among groups in a demographic sense. Darwin tended to view it as individual competition. Remember, I said Darwin collected individual species and would examine them in great, great detail — maybe just a few different species — whereas Wallace was collecting huge numbers, 125,000 species.
