PPT-Survivor: A Game of Traits and Natural Selection

Spring 2019 Vanderbilt Student Volunteers for Science I Introduction Why is Charles Darwin so important Concluded that organisms changed over time to better survive in their specific environments. Change over time…. Geology. Began to study rock layers called strata. George Cuvier. Studied fossils. Found extinct species and noticed the deeper the fossil the more unique. Catastrophism. Charles Lyell. Evolution- changes in the characteristics of groups of organisms over time . Charles Darwin was the first to propose a feasible . mechanism. for evolution. It is called . natural selection. . . Evolution by Natural Selection is a theory. . Chapter . 11 Page 307. A. . Genetic Variation Within Populations. Genetic variation increases survival rate. Natural selection works on phenotypes differently. Wide range of phenotypes = greater chance of survival with changing environment. Adaptation, Mutation, and Finches?. Natural Selection. Natural selection means that traits that offer an advantage will most likely be passed on to offspring; individuals with those traits have a better chance of surviving. . Nowhere to Hide. The concept of Natural selection. Individual organisms of the same kind differ in characteristics. Name some characteristics. Sometimes these differences give individuals an advantage in surviving and reproducing. What is natural selection?. It’s the . process whereby organisms better adapted to their environment tend to survive and produce more offspring. . The . theory. of its action was first fully . explained . Selective Breeding. What is . Selective Breeding?. Selective breeding is the process of breeding plants and animals for particular traits. The term selective breeding is synonymous with artificial selection. Evolutionary Ideas. A. lthough Darwin is given much credit for evolutionary theory, he was not the first person to come up with the idea.. Evolution is the change in a population over time.. The concept of evolution had been discussed for more than 100 years prior to Darwin’s theory.. Chapter 8B. History of Evolutionary Theory. I. History of Evolutionary Theory. Definitions. 1. Evolution. Evolution. The gradual change that causes something to improve or become more complex. Ex.) The . According to evolutionists. Characteristics of Organisms in the Galapagos Islands compared to nearby South America. Darwin hypothesized that animals came to the . Galapagos. from the . mainland. and they became . you need . 2. . sheets of lined paper. Vocabulary Diagrams. This is a pencil!. Do now activity: make . 7. . diagrams. Vocab Word. Teacher Definition. Student Definition. Student Sentence. Teacher Sentence. A. Species overproduce offspring that may survive an environment.. B. There is little variation among members of a population.. C. Competition for resources, mates, and space among species leads to a struggle to survive.. What is . Selective Breeding?. Selective breeding is the process of breeding plants and animals for particular traits. The term selective breeding is synonymous with artificial selection. .. This . selection process .
