In English literature, William Wordsworth (1770-1850) and Samuel Taylor Coleridge (1772-1834) were first-generation Romantic poets, and Byron (1788-1824), Shelley (1792-1822), and Keats (1795-1821) were second-generation Romantics.

9453319837Aristotlebelieved things could be arranged on a "scale of nature", increasing complexity. Organisms were arranged on a ladder.0
9453321831Linnaeusdeveloped taxonomy, the study of naming & classifying organisms; binomial nomenclature. Domain, Kingdom, Phylum, Class, Order, Family, Genus species (scientific name) ex. Homo sapiens1
9453323879Georges Cuvierfather of paleontology, studied sedimentary rocks, believed in extinction and catastrophism. Opposed evolution.2
9453325984James Huttondeveloped Gradualism, change happens by a slow, continuous process3
9453329314Charles Lyellgeologic processes have not changed since the beginning of time, rate of erosion has not changed4
9453331083Jean - Baptiste Lamarckpublished theory of evolution in 1809 (same year as Darwin's birth). Came up with two ideas: 1)theory of use & disuse: those parts used to cope with the environment become larger/stronger, those not used go away (ex) blacksmith develops larger biceps, giraffes neck stretches to reach trees 2)inheritance of acquired characteristics: changes can be passed on to offspring, dyed hair color NO evidence that acquired characteristics carried on - blacksmiths arm not passed on5
9453336977Charles Darwin(1809-1882) became clergyman, HMS Beagle voyage around the world, collected different specimens & made observations at all stops during trip. Galapagos Islands - finches, mockingbirds, 1836 - returned from voyage 1844 - wrote an essay on natural selection but did not reveal his discovery 1858 - Alfred Wallace wrote telling that he had found the same discoveries as Darwin; Darwin submitted his essay; published it 1859 On the Origin of Species. 2 main points in paper: 1) species today came from ancestral species 2) developed term "natural selection" populations change over time *uses term descent with modification rather than evolution, he believed that the history of life was like a tree6
9453345933Darwins Main Ideas1. Natural selection is differential success in reproduction 2. Natural selection occurs through an interaction between the environment and the variability inherent among the individual organisms making up a population 3. The product of natural selection is the adaptation of populations of organisms to their environment.7
9453350113Examples of Natural Selection1. Insecticide resistant insects - new spray kills 99% of bugs, 1% continue to live and pass on resistant genes, over time few bugs will be resistant 2. Drug resistant bacteria - resistance in individuals occurs early, MRSA8

9453355940Homologous structuresthose that contain the same bones but the structures have different functions in different animals. The same bones make up the forelimbs of mammals. (bat wing, human arm, whale flipper)10
9453356866Vestigial organsthose that have little or no value now, but once did. (wisdom teeth, hip bones in snakes, appendix, tonsils)11

9453393069Evolutionary FitnessIndividuals with more favorable phenotypes more likely to survive and produce more offspring, and pass traits to future generations22
9453398982natural selection ideasEvolution is change in species over time. There is overproduction of offspring, which leads to competition for resources. Heritable variations exist within a population. These variations can result in differential reproductive success. Over generations, this can result in changes in the genetic composition of the population23
