Unformatted text preview: Lecture 2: Evidence for Evolution Evidence for Evolution Evidence for Evolution OR Data that demonstrate change over time and common descent OR The Pattern of Evolution Evidence for Evolution Nothing in Biology Makes Sense Except in the Light of Evolution. --Theodosius Dobzhansky Evolution is one of the single best supported theories in science. It is supported by data from- biology (genetics, ethology, ecology, anatomy...)- geology- biochemistry- physics- anthropology Evidence for Evolution Nothing in Biology Makes Sense Except in the Light of Evolution. --Theodosius Dobzhansky Outline I. A Few Key Early Players- Linnaeus, Lamarck, Lyell, Darwin II. Evidence of change over time- extinctions- observations of change in nature- experimental evolution- artiFcial selection/domestication III. Evidence of common ancestry- homology & transitional forms- vestigial traits- biogeography History of the idea Much data was accumulated and the pattern of evolution proposed prior to Darwin proposed nomenclature for organization - not based on evolutionary relationships 100 Swedish Krona Note Systema Naturae Linnaeus soft inheritance inheritance of acquired characteristics Lamarck Jean-Baptiste Lamarck Species were spontaneously generated and change through time. Individuals meet environmental change with behavioral changes, which in turn drive physical changes; use or disuse of an organ causes changes in individuals, and these new forms are passed on to offspring. Jean-Baptiste Lamarck Methylation & Genomic Imprinting Principles of Geology uniformitarianism uniformitarianism- philosophical view that geological and biological processes work now in the same manner and with the same intensity as they always have Lyell Smoky Mountains 750 m.y.o.
