Unit 3 - Question 3:
Darwin’s theory is often simplified as “Survival of the Fittest” and carries the misconception that “fittest” means perfectly adapted. Explain why natural selection does not produce “perfect” organisms.

6. (Answer this question using the neutral theory of molecular evolution) One of Charles Darwin's main ideas was that life evolves by natural selection, following a rule of "survival of the fittest." For example, if you look historically at giraffes, it is hypothesized that those with taller necks tended to be selected for evolutionarily because they could reach more food high up in trees. When we consider DNA, the same principles of natural selection apply. Those DNA regions that have...

Question 3: Explain why the fixation time of a beneficial, recessive allele is often much longer than that of a beneficial, dominant allele. (2 points) Question 4: Name two types of natural selection that can maintain polymorphism. (2 points) Question 5: Consider an annual plant population in an environment with alternating dry and wet years. You observe the dry and wet years are equally frequent. At a locus with two alleles (A1 and A2), the relative fitnesses of the three...

The Prisoner's Dilemma utilizes game theory to explain behavior of firms in: Markets characterized by natural monopoly. Monopoly markets. Perfectly competitive markets. Monopolistically competitive markets. Oligopoly markets At 500 units of output, total costs = $50,000 and total variable cost = $5,000. What does average fixed costs (ATC) equal at 500 units? $45,000 $50. $100. $90. Statement 1: Marginal cost pricing occurs when the market price of a good is equal to the marginal cost of the last unit of...

1. Population is not used in describing species. Population is a group of organisms of the same species populating a given area, a group of individuals of the same species that live in the same area and interbreed, producing fertile offspring. Interbreeding, sexual reproduction, natural selection and color are used in describing species. Individuals in an interbreeding population share in a common gene pool. My question is can you tell me how interbreeding, sexual reproduction, natural selection and color are...
Climate change is a threat to the existence of many species.
QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...

Question 6 1 pts In light of the previous question, how can we explain the fact that the Hawaiian bobtail squid has clearly evolved to precisely control the association with its bacterial symbiont, whereas the bacterium shows no signs of adapting to the same symbiosis? (Why does the animal host appear to be 'winning the evolutionary race to control their interaction?) squid have remarkably high mutation rates It is actually best for the bacterium to simply let the squid evolve...

Although the following scenario is hypothetical, it is based on actual facts. Sickle cell anemia is an inherited form of anemia. Those with sickle cell anemia do not have enough healthy red blood cells to adequately carry oxygen to all the cells in their body. Normal red blood cells are flexible and round, and can easily move through the blood vessels. However, in...
