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.

Ch. 16-1 Natural selection makes an adaptive trait more common in a population. After many generations, will all individuals in the population have the same adaptive trait?
17. Which of the following statements best explains the Theory of Natural Selection? * a. Organs that are not used may disappear, while organs that are constantly used may develop b. In nature, the organism with desirable characteristics may survive, while those weaker traits may not c. Organisms develop desirable structures to survive in a given environment d. Acquired characteristics of parents can be passed on to offspring 18. Larry Daley is a paleontologist found out some Central American Acacia species that have hollow thorns and pores at the bases of their leaves that secrete nectar. He used the species to understand the history and origin of the place. From the given situation, the Central American Acacia species is an example of _____________. * a. evolution b. fossil c. mutation d. coevolution
Tiny foxes live on the Channel Islands off the coastof Southern California; the adults weigh less than3 lbs. These so-called island foxes (Urocyon littoralis) derived from the mainland gray fox (Urocyoncinereoargenteus). Analysis of genome sequencesrevealed that unlike the mainland foxes, the foxeson a single island have shockingly little geneticdiversity.a. The genome of only one fox from each island wassequenced. How would the lack of genetic diversitybe evident in a single genome sequence?b. The populations of the foxes on each island aresmall. How might the low diversity have occurred?c. Why is low genetic diversity thought to lead tospecies extinction?d. Hypothesize as to why the Channel Island foxesare thriving without human assistance despite theirlack of genome sequence diversity
23 . When constructing a cladogram, which of the following is considered most useful for determining evolutionary relationships? Group of answer choices shared derived characters vestigial structures homoplastic characters morphological similarities shared ancestral characters
12. Which can bring new traits to a population and why? 1. natural selection - because it increases the frequency of adaptive alleles in a population over time 2. natural selection and mutation because both increase the frequency of adaptive alleles in a population over time 3. mutation - because it increases the frequency of adaptive alleles in a population over time 4. natural selection and mutation because both make new alleles 5. natural selection - because it makes new alleles 6. mutation - because it makes new alleles
List the ways in which evolution can affect population variation and describe how they influence allele frequencies.
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
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 above

Microevolution is defined as a change inallele frequencies in a population over generations. Please explainwhat an allele is, in genetic terms. Name the three major factorsinvolved in allele frequency changes in populations. Describe, indetail, how natural selection works on individuals, while evolutionoccurs in populations. Include a real or hypothetical example ofthe process of natural selection in your answer other thaninsects and insecticide! Identify the specific natural selectionpressure and the specific trait being selected for in yourexample.
Revise the passage Darwin is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin's first book dealing with natural selection was published in 1859):Based on these observations and inferences, Darwin concluded that these traits, called adaptations were the product of evolution by Acquired Traits, these traits made the members of the population who had them equally fit for survival. an organism could also change during their lifetime in order to adapt to its environment, those changes are passed on to its offspring. For example, darwin believed that if giraffes stretched their necks to reach food, Their offspring and later generations would inherit the resulting long necks.
