EVOLUTION and NATURAL SELECTION (30 pts) a. What is a mutation? Provide 3 examples of different mutations causing specific diseases in human population. For each example explain what kind of mutation that is (ie. A point substitution‚ a chromosomal duplication etc). Mutation is a genetic mistake(s) that occur during DNA replication. 1. Progeria accelerated aging; mutation in the LMNA gene 2. Hypertrichosis excessive hair on the shoulders‚ face and ears; implicate it to a rearrangement

Question 2 Which of the following is not a step in the scientific method? D. Scientific Law Question 3 When an organism’s DNA is permanently altered‚ we say that it E. mutates. Question 4 Which answer choice is not a defining characteristic of life? C. disorder

A. Evolution and Behavior 1. Study microevolution by viewing domestication and natural selection in the wild. 2. Domestic dogs attack prey differently than their ancestral wolves do due to behavioral selection 3. In domesticating foxes‚ you are selecting for neotenous traits and a suppressed adrenal gland that made the foxes less aggressive 4. Natural disasters or major ecological changes are good examples of looking at microevolution 5. When studying behavior

of a geographic scale was certainly appreciated by Darwin: the Galapagos finches were morphologically distinct and geographically distinct and there must be a connection. Moreover‚ the general view that speciation is a central phenomenon in evolution‚ and that most speciation is allopatric speciation assumes that geography plays a central role: some

Ring Species: A Catalyst for Speciation After spending time on the Galapagos Islands studying the origin of various species‚ former divinest Charles R. Darwin proposed the evolutionary theory of natural selection‚ a mechanism by which advantageous variations in a population are preserved while unfavorable variations are lost (Berkeley‚ 2008). As a result of these variations‚ some individuals are better acclimated to their environment than others. This results in the better-suited individuals outcompeting

Format your references consistent with APA guidelines. 1. What is the direct evidence in support of the theory of natural selection? Include at least four examples. Paleontology shows us that organisms have changed gradually over time‚ as reflected in the fossil record. Biogeography shows us how new species only arise
Premium Evolution Natural selection
Evolution Generally‚ evolution is any process of change over time. In the context of life science‚ evolution is a change in the traits of living organisms over generations‚ including the emergence of new species. Since the development of modern genetics in the 1940s‚ evolution has been defined more specifically as a change in the frequency of alleles in a population from one generation to the next. Darwin ’s theory of evolution describes the descent of all living organisms from a common ancestor
