Apply the VIDA table to the evolution of sickle cell disease to justify whether it is an instance of evolution by natural selection. Answer the following questions.
Is there variation in this trait in the population? How exactly does it vary? Is the trait at least partly inherited? Is there selection for this trait in a particular environment? (What is the selective pressure? And how does a trait give an advantage or disadvantage in that environment?) What is the evidence that this trait makes organisms better adapted to their environment?
Genetic variation is the product of completely random events, but acting upon this randomness is a very nonrandom process called natural selection. Explain or give an example.
One of the lines of evidence that led Darwin to the theory of natural selection was his study of artificial selection. Plant breeders and pigeon breeders select offspring with specific traits in mind beforehand.
a) However, since humans are an integral part of the natural world, do you think that artificial selection might be more appropriately termed “natural selection”? Why?

- List and explain the three types of natural selection.arrow_forwardWhich of the following statements does NOT agree with the tenets of Darwin's theory of evolution by means of natural selection? O A. The phenotypes of individuals in a population will differ and, in some cases, these differences are the result of traits passed down from parent to offspring. B. Phenotypes become more common over time if individuals with those phenotypes have higher reproductive success. O C. The fitness of an individual with a particular phenotype is independent of the environmental conditions it experiences. O D. Resources limit the total number of individuals in a population.arrow_forwardWhich of the following factors are required in order for evolution to occur? a. Individuals within a population must be receptive to change and collectively determine which trait(s) is/are to be modified in subsequent generations b. Genetic variation within a population must exist or have the potential to arise, and shifts in allelic frequencies will take place or have the potential to take place c. Individuals within a population should be able to reproduce effectively (i.e., without barriers to reproduction existing) d. Both A & B e. Both B & Carrow_forward

- Darwin put together several pieces of information when formulating his theory of evolution. Which of the following is/are not part of that information? Choose All That Apply Natural populations of organisms display variable phenotypes Natural populations tend to produce more offspring then the environment can support Individuals within a population can pass on traits acquired during their lives to their offspring Organisms tend to be uniquely adapted to the environments in which they are found Each individual in a population is equally likely to survive and produce offspringarrow_forwardThe theory of evolution by Darwin is a composite theory, i.e. it has five component theories: 1. Evolution as such is the simple proposition that the characteristics of lineages of organisms change over time 2. Common descent is a radically different view of evolution than the scheme Lamarck proposed. Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. 3. Gradualism – Darwin’s proposition that the differences between even radically different organisms have evolved incrementally, by small steps through intermediate forms. The alternative to this theory, as discussed in later sections, is saltation with great reference to large differences that are believed to have evolved by leaps without intermediates. 4. Populational change – Darwin’s thesis that evolution occurs by changes in the proportions of individuals within a population that have different inherited characteristics. 5.
