Anaximander (6th century bce): greek philosopher, believed in common descent (common ancestor, transmutation of species (new species arise from existing species) 2400 years before darwin: no one took him seriously, gave us concept of ancestry. Jean-baptiste lamarck (1744-1829): first complete theory of evolution, supernatural forces placed organisms on earth to create variety, other forces cause adaptation. Leads to use or disuse of specific traits: believed offspring inherited acquired traits (not true, gave us concept of adaptation. Thomas malthus (1766-1834): populations grow geometrically, food supplies grow linearly, populations grow faster than food sources, epidemics (diseases, war, disasters, etc. ) collapse population enough so that there is enough food. If epidemics fail, food is the ultimate population control: premature death is necessary for the survival of a whole species, gave us concept of population control. Charles darwin (1809-1882): father was a doctor, enrolled darwin in medical school.
