Lagniapposis is caused by a microparasite,Boudreauxia thibodauxi, and is transmitted directly bycoughing and sneezing. It is highly transmissible and veryvirulent. Infected hosts become immune after a week if they do notdie. Use the equation for directly transmittedmicroparasites to discuss the following.

2.Suppose that an organism is suddenly infected with a new pathogen and subsequently infects other members of its species. Infection with the pathogen results in ill effects on the hosts. Which of the following is FALSE:
| a.The reservoir for this pathogen may have been another species, where it may have been present for a long time before making the jump. |
| b.The reservoir for this pathogen may have been another species, but this species had to have been a close relative of the newly infected species. |
| c.The new pathogen will likely have a more virulent effect on the newly infected species than would a pathogen with a longer-term presence. |
| d.The newly infected species may happen to have encountered other pathogens in the past that it has evolved to deal with, which confers some resistance to the new pathogen. |
3.Which of the following is TRUE:
| a.Most human variation exists within groups rather than between them. |
| b.Human races are properly classified as 'sub-species', because there are clear differences in traits that we commonly categorize as 'racial features'. |
| c.Eugenics had its roots in thoroughly well-grounded science, and made use of the clearest thinking about human genetic variation and the factors that went into shaping human characteristics. |
| d.Evolutionary medicine is an outdated and racist idea that sought to make human beings subject to the whim of prevailing social norms and ideas of "innate superiority". |
