Textbook Question
Chapter 1, Problem 14Q
Authors in various fields often make interesting statements about evolution:
- (a) A traditional view, particularly in parasitology and medicine, was that relationships between
parasites and their hosts inevitably evolve toward peaceful coexistence (see Ewald 1983). Among the arguments for this view was that a parasite population is likely to survive longer if its host remains unharmed. Are the traditional view and the argument for it consistent with what you know about HIV—and about other diseases and parasites? What experiments do they suggest? - (b) HIV is a tiny, robotic, molecular machine. Many science fiction books describe robots that evolve to become intelligent and conscious (and, usually, seek freedom, develop emotions, and start wars with humans). Under what conditions could robots actually evolve? Is it necessary that the robots reproduce, for example?

The Simian Immunodeficiency Virus (SIV), is an HIV-like virus that originally attacks the immune system of monkeys and apes. In 1999, researchers identified a strain of chimpanzee SIV called SIVcpz, which was nearly identical to HIV. Which of the following conclusions could be drawn from the similarities and relatedness that exist between humans and primates based on respective strains of viruses?
Mosquitos are vectors of the Simian Immunodeficiency Virus (SIV), and HIV. Once injected with their proboscis and introduced viruses into the human bloodstream, viral mutations occur.
Human immunodeficiency virus has reverse transcriptase so it is easier for them to transform into another strain of the virus.
The introduction of new viral strains is inevitable and they do not possess selectivity. Both immune host cells from humans and chimpanzees are susceptible to any viral infection.
Humans and Chimpanzees were similar so it is easier for the Simian Immunodeficiency…
The application of evolution to understanding disease is widespread and productive. What is the benefit of applying Darwinian principles to medical practice?
Wolbachia is a genus of bacteria that infect cells of invertebrates. Surveys have found that up to a
fifth of insect species have at least some individuals infected with Wolbachia. Pathogen or
parasite? This endosymbiont (a symbiont that lives inside its host) bacteria can have many effects
on its host, including killing offspring and changing the sex of offspring.
Ary Hoffmann from the University of Melbourne in Australia, Michael Turelli from the University of
California at Davis, and their associates have been studying Wolbachia infections in populations of
Drosophila simulans from California. From the initial infection around 1980, Wolbachia infection
spread northward across the state during the 1980s and 1990s. The most striking manifestation of
infection in this fly species is cytoplasmic incompatibility: offspring produced in crosses where
males are infected and the females are uninfected tend to die early in development. In crosses
between infected males and infected females,…

Use the word: mutationarrow_forwardSuppose that a time machine allows you to go back in time (and to travel to Australia), and you have collected rabbits and Myxoma from the years 1955 and 1980. Once you are back in the twenty-first century, you infect both sets of rabbits with both sets of Myxoma viruses. The most likely result will be (1) that the rabbits from 1955 injected with the 1955 virus will have a survival rate than those same rabbits injected with the 1980 virus; and (2) that the rabbits from 1955 injected with the 1980 virus will have a survival rate than rabbits from 1980 injected with the 1980 virus..

- Why do scientists worry more about new strains of viruses like influenza and coronviruses as potential causes of deadly human pandemics, but they never talk about the next big Herpesvirus strain deadly pandemic? Which of the statements below helps partially answer that? We already have effective vaccines for Herpes. Influenza and CoV have more genes, more complex gene expression, and can undergo genetic recombination or reassortment, while Herpesviruses are more limited. Only humans get Herpesviruses, while animals can get Influenza viruses and Coronaviruses. dsDNA viruses aren't very transmissible and even when they are, they're not deadly. Influenza and CoV are RNA viruses which results in having higher mutation rates -- they can more easily jump between host species. Herpesviruses are dsDNA viruses and usually very host specific.

Some people may have concerns about the use of phages in foods. From what you have learned about bacteriophages and viruses, why do you think we do not have to be concerned about the presence of bacteriophages in food?arrow_forward"Early in the COVID-19 pandemic, some argued that comparable numbers of people caught bad strains of the influenza virus (causing the viral flu); thus, by extension, the restrictions imposed on society for COVID-19 were unduly burdensome. Based on our discussion in class, which arguments could be made to refute this argument. " "While an average of 31 million people catch the viral flu each year in the US (compared to 16 million COVID-19 cases so far), the mortality rate from the flu seems to be perhaps 8 to 24 times lower than for COVID-19." "Fewer people have caught COVID-19 than catch the viral flu in a given year, but the comparison is not entirely fair since we are not restricting social gatherings or wearing masks during viral flu seasons. A fair comparison would be what would have happened with COVID-19 infections if normal year practices were carried out.

- If it is possible asnwer all the following questions, if not, i would like to know about question 2 and question 3. thank you. 1. Why is the statement, humans evolved from monkeys, incorrect? 2. In recent years, strains of bacteria resistant to antibiotics have created serious health care challenges for our society. Based on what you've learned about natural selection, explain how the overuse of antibiotics could influence the evolution of bacterial diseases. 3. How does the peppered moth example demonstrate that evolution is directional? 4. Is is viable to believe both in creation and evolutionarrow_forwardThe discovery of HIV virus was a race between two groups of scientists. Do you think the scientistic research should be a “race”? What are the pros and cons of such a race?arrow_forwardIn 1918, an influenza pandemic that originated with avian flu killed 50 million people. Researchers isolated samples of that virus from bodies of infected people preserved in Alaskan permafrost since 1918. From the samples, they sequenced the viral genome, then reconstructed the virus. The reconstructed virus is 39,000 times more infectious than modern influenza strains, and 100 percent lethal in mice. Understanding how this virus works can help us defend ourselves against other deadly influenza strains that arise. For example, discovering what makes it so infectious would help researchers design more effective vaccines. Critics of the research are concerned: If the virus escapes the containment facilities (even though it has not done so yet), it might cause another pandemic. Worse, terrorists could use the published DNA sequence and methods to make the virus for horrific purposes. Do you think this research makes us more or less safe?arrow_forward

A. No, because there isn't a genetic basis for inheritance between parent and offspring virus particles. B. No, because there isn't a way to distinguish more fit from less fit virus particles C. Yes but only via human (domestic/artificial) selection D. No they evolve by mutations. E. Yes, virus particles that are most successful successful in reproducing quickly and infecting other host cells are the best adapted.arrow_forward
