Document Summary

Late 1700s = transmutation what was the mechanism: john baptiste de lamarck (french naturalist) Darwin and alfred russell wallace: agreed with lamark evolution due to environment adaptation, why change occurs, disagree how change occurs. Die before reproduce: struggle for existence : variation in populations, natural selection. Those that survive have variants which are more adaptive in an environement. Lamarck thought characteristics were acquired but to darwin, there"s an already existing variation: survive and reproduce survival of the adaptable. Existing variation some variants survive and are reproduced. Does not create variations only edits it. Humans can be goal-oriented artificial selection (eg: race horses, dogs, etc. ) Natural selection not goal-oriented can always envision better solutions to adaptive problems. As put forth by darwin, darwinian evolution not complete. Had an idea how it worked but underlying mechanisms not known.
