Or possible answers after the due date. Our book states that all animals have an innate immune system but only vertebrates have an adaptive immune response. Why do you think this might be? What selective advantage favored vertebrates but not invertebrates for having an adaptive immune response? Explain your reasoning. - Recall that Jean-Baptiste Lamarck was one of the first to study the idea of evolution systematically (p. 450 of our text) and proposed the idea of inheritance by acquired characteristics, where individuals develop phenotypes in response to environmental changes. Could it not be claimed that Lamarck was correct in his thinking with regards to our immune system? Provide one example where our immune system supports his acquired characteristics idea and one reason that it does not. 3. Africa Sleeping Sickness is caused by a single celled parasite, Trypanosoma, that infects our blood cells and liver. This parasite has proven difficult to immunize people against with most vaccinations proving unsuccessful. Examine the graph below showing infection concentrations of the parasite over time in the blood of an infected person along with the percent production of certain antibodies displayed on the second y-axis (on the right side). Propose a hypothesis and explanation for why many vaccines have been unsuccessful in immunizing people against the pathogen, Can You think of a genetic mechanism Tre
