- Do Q1 Applying concepts both part a as well as bNeed help List the four types of evidence that exist in support of evolution.Explain.Question:- Select all of the statements about correlated trait evolution that are accurate. Group of answer choices a. genetic correlations may be beneficial, harmful, or neutral b. our in-class example of a correlation between different beak size and shape traits in Darwin’s finch was in example of genetic correlation (this was given in lecture so i know this is an answer) c. genetic correlation necessarily involves pleiotropy d. correlated selection necessarily involves pleiotropy e. antagonistic pleiotropy may occur with correlated selection f. our in-class example of a correlation between garter snake scalation patterns and escape behavior was in example of genetic correlation
- Wyckoff et al. (2000. Nature 403:304-309) have proposed that some human male reproductive-associated genes have evolved by natural selection and not by neutral evolution. Part of the DNA sequence results of their study is shown below. Which gene(s) did seem to evolve by natural selection? Note: dn = number of substitutions per non-synonymous (replacement) sites and ds = number of substitutions per synonymous (silent) sites. dn ds Acrosin-Trypsin 0.138 0.064 Protamine 1 0.133 0.046 SRY 0.055 0.090 Histone H1 (testicular) 0.055…Evolution of Human beings acceptable theory?QUESTION 52 The most accurate phylogenies use… a. Analogous characteristics b. Evolutionary reversals c. Homologous characteristics d. Homoplastic characteristics
- Follow up on Question 2. The purpose of including species D in the phylogenetic reconstruction is so that it can be used as a. an in-group for inferring the polarity of trait evolution b. an out-group for inferring the polarity of trait evolution c. an ancestral group for inferring the polarity of trait evolution d. a monophyletic group for classifying vge gene types e. None of the aboveWhat is the role of variation in evolution – if heterozygosity is reduced, what happens to the potential for evolution?25. Answer the following questions based on the facts and inferences related to natural selection that we discussed in class, as well as the simulations you performed with the Evodots lab. If individuals vary, and variation affects survival and reproduction, and variation is heritable: there will be natural selection resulting in evolution. there will be no natural selection, but there will be evolution due to natural selection. there will be natural selection, but it will not result in evolution. there will be no natural selection, and there will be no evolution due to natural selection. 24.

- Microtaxonomy ( Species and Speciation ) People who do not believe in evolution often cite the classic example of man presumably evolving from the apes. They oftern ask: if humans evolved from apes, why are there apes until today? How will you provide a convincing answer that there is no contradiction in the existence of apes and humans at the same time?1. a) How does this experiment demonstrate the definition of evolution? b) Fitness of organisms is a function of the environment (that is, organisms best fit to the local environmental conditions leave more surviving offspring). How does this experiment demonstrate this fact?Question 4 Developmental Systems Theory (DST) views evolutionary change as all of the following EXCEPT: Question 4 options: genotype change occurring through phenotype-environment interaction. more than genotype change occurring through phenotype-environment interaction. a complex organism-environment system. a system in which organisms can influence their ecologies and thus the selection pressures on themselves. Question 8 An evolutionary process in which a small group of individuals account for all of the genetic variation in a large population is called a(n): Question 8 options: originator effect. chance effect. founder effect. random effect.
