He demonstrates the fact of extinction with studies of fossil mammals, and believes the extinctions to have occurred in a series of giant floods. Proposes that while simple forms of life were spontaneously generated, they were driven up a ladder of complexity over time. Use or disuse of organs and traits cause changes which could be passed on to the next generation. Further develop the ideas of Jean- Baptiste Lamarck & Erasmus Darwin to propose that plants and animals had a common evolutionary starting point (a view wrongly discredited by Richard Owen). 1830-18451830 Charles Lyell 1831 Charles Darwin 1845 Alexander von Humboldt 1856 Neanderthal discovery Neanderthal skull and bones are found in Neander valley in Germany. 1858 Alfred Russel Wallace Alfred Russel Wallace (1823-1913) independently conceives the theory of evolution by natural selection and co-publishes with Darwin on the subject. 1860 Oxford Evolution Debate Proponents and opponents of Darwin & Wallace’s theories clash in the famous Oxford Evolution Debate; Thomas Henry Huxley (1825-1895) and Samuel Wilberforce (1805-1873) butt heads in a public debate, which both sides consider a victory. 1871 Charles Darwin 1893 August Weissman 1896 James Mark Baldwin 1909 Wilhelm Johannsen Wilhelm Johannsen (1857 1927), a Danish biologist, provides the basic Jded@ terminology for genetics: ‘genes’ as particulate units of heredity; ‘genotype’ as the genetic constitution of an SSS a and ‘phenotype’ as the organism ’ 5 4 ; physical characteristics.
