- Topic: Role of Molecular Biology in Evolutionary Classification How does the recently developed DNA technology help scientists establish a more accurate classification scheme? Information on DNA can often indicate relatedness between organisms and even provide data on how long they have been evolving separately. Discuss the influence of DNA and molecular biology on the future of evolutionary classification.arrow_forwardGenomics and Human Evolution The Denisovan genome contains sequences that originated from an unknown human species. Using Figure 19.11, speculate on which species this might be. Is it possible that there are other ancestral species that may remain to be discovered that would change the phylogeny presented in the figure? FIGURE 19.11 Estimates for the dates of origin and extinction for the three main groups of hominins (green, blue, and orange). The australopithecines split into two groups about 2.7 million years ago. One of those groups, the genus Homo, contains the ancestors to our species, H. sapiens.arrow_forwardAnthropologie How evolution happens? What is natural selection and how does it work?

- Worksheet: What Darwin Never Knew Darwin was a naturalist, or a collector of plants and animals from around the world. He made observations that made him more and more curious about the origins of life, and relationships among species (remember--making observations is the first step in the scientific method). Give two examples of such observations from birds, turtles, snakes, whales and/or embryos. From his observations, Darwin concluded that all species were connected. How did dogs and artificial selection (or artificial breeding) shape Darwin’s idea about the tree of life in nature? Darwin proposed natural selection to explain the diversity of species in the world. How did his travels to the Galapagos Islands off the coast of South America shape his thinking? Why is variation of individuals within a species so important to the theory of evolution? Explain using mutations in the fur color of pocket mice of the Arizona desert.

Review the process of natural selection. Use the steps to explain how PCB resistance became so common among tomcod in the Hudson. Be sure to include the terms mutation, fitness, selective pressure, and adaptation in your explanation. 2. In this blog post, the author describes the tomcod as "a quick learner" because of the population's adaptation to PCBs. Is "learning" an accurate way to describe the change in the Hudson River tomcod population? Why or why not? 3. The data shown on the map above support the hypothesis that natural selection for PCB resistance has occurred among tomcod in the Hudson. What sort of evidence regarding gene frequencies in different populations would argue against this hypothesis (i.e., imagine what the scientists would have observed in this study if natural selection on the AHR gene had not occurred among Hudson River tomcod)? 4.
