the study of structural similarities and differences among living things, homologous structures, comparative anatomy, divergent evolution, analogous structures, parts of different organisms that have similar structures and similar embryological development, but have different forms and functions. , homologous structures, comparative anatomy, divergent evolution, analogous structures, What are examples of homologous structures. Click all that apply, human arm and hand, sedimentary rock, fossils, whale flipper, wing of bats, The hisotry of life indicated by fossils, sedimentary rock, stone age, fossil record, fossil footprint, True of False: Earliest organisms were simple and have become more simple over time., True, False, True or False: Gaps in the fossil record exist, True, False, True of False: Most (more than 99%) of species are extinct., True, False, Which are ways to calculate the age of fossils? click all that apply, sedimentary rock, oxygen, Great dating, absolute dating, relative dating, Nitrogen-14, Fossils, amber and ice, fossil bones and petrification, molds, casts and imprints are?, ways to calculate the age of fossils, ways to find evidence from the past, determine evolution, What are two types of evolution?, world and natural, sedimentary and fossil, organic and geologic, Exemplified with homologous structures shows common ancestry. Parts of different organisms that have similar structures but different functions, organic evolution, comparative anatomy, divergent evolution, analogous structures, Structures that have similar external forms and functions but different internal structures. Ex. bird wings and insect wings, homogous structures, analoagous structures, divergent evolution, comparative anatomy, convergent evolution, The evolution of outward similarities in organisms that are not closely related, because they have to meet similar problems in their habitat., divergent evolution, comparative anatomy, convergent evolution, Remnants of structures that were functional in an ancestral form. Are reduced in size and serve little or no function. Ex. appendix, wisdom teety,, embryological similariteis, comparative embryology, vestigal structures, comparison of the embryological development of different species. Embryos of closely related species show similar patterns of development., comparative embryology, molecular similarities, comparative biochemistry, The more closely related the species are to one another, the greater the biochemical siilarities. DNA, Amino acids, comparative embryology, molecular similarities , comparative biochemistry, French biologist who believed that species changed, and evolved from preexisting species. Evolutionary changes were caused by their NEED to adapt to environmental changes, Darwin, Jean Baptiste de Lamarck, The Beagle, The Law of Use and Disuse and The Inheritance of Acquired Characteristics came from, Darwin, Lamarck, He wrote On the Origin of Species by Means of Natural Selection, Darwin, Lamarck, On a visit to the Galapagos Islands, species here were unique and different from those on the mainland. The beaks of the bird had adapted to different tasks., Darwin , Lamarck, Developed the idea of natural selection, Lamarck, Darwin, Choose three of Darwin's main points, overproduction, racing, evolution, competition, variation, Choose three main points of darwin's theory, biology, embryo, adaptations, natural selection, speciation, An inherited trait that aids the chances of survival and reproducion of organisms. There is structural, physilogical and behavioral, adoption, adaptations, evolutions, True or False: Populations and species evolve, not individuals, true, false, Which are observed natural selections, industrial melanism, bacterial resistance to antibiotics, insect resistance to DDT, bandaids not working, would occur if individuals at one end of the normally distributed curve are favored. Giraffes, directional selection, stabilizing selection, disruptive selection, removes the extreme neds of trait distribution. An example might be birth weight of humans. Mortality rates at birth are highest at both ends of the normally distributed birth size range curve, thus tending to keep birth weight constant and near the mean., directional selection, stabilizing selection, disruptive selection, would occur if selection simultaneously favored individuals at both ends of the curve., directional selection, stabilizing selection, disruptive selection, Emergence of numerous species from a common ancestor introduced to new and diverse environments. Ex. Darwin's Finches, Adaptations, Adaptive Radiation, Adoptions, Bottleneck Effect and Founder Effect are , water drift, drink drift, genetic drift, DNA drift, A change in gene pool of a population due to chance not natural selection, bottle neck effect, genetic drift, founder effect, True of False: The smaller the population=the more impact genetic drift has on that population, True, False, An event nearly wipes out a population, leaving only a random small group, bottleneck effect, founder effect, can occur if a small number of individuals colonize and new area., bottle neck effect, founder effect, It is a sudden and quick process, genetic drift, natural selection, It selects harmful or useful variations by chance, genetic drift, natural selection, It is a gradual and slow process. Can be rapid, genetic drift, natural selection, It selects only adaptatively useful variations, genetic drift, natural selection, Evidence of Endosymbiotic Theory: click all that apply, orangelles, membrane, DNA, reproduction, punnet square, Which are beaks of Finches: click all that apply, forceps, clothespins, none of the above, test tube holder, beaker tongs, crucible tongs.
