For each of the following scenarios, identify what microevolutionary process is occurring (be as specific as possible) and also indicate what effect (if any) it will have on the genetic diversity of the population 1 Some birds with shorter beaks enter into a population of birds with much longer beaks, resulting in several offspring with in-between sized beaks in the next generation. 2 Male Gorillas fight each other for the rite to be the male head of the troop (-silverback). The silverback will then have exclusive mating rights with all the mature females in the troop. 3 For years the tuberculosis bacterium was successfully treated with penicillin but one year a patient contracts the disease and the penicillin treatment is no longer effective as the bacteria have suddenly become resistant to this antibiotic. 4 A species of butterfly has a solid coloration pattern that ranges from light to dark green. One population living in an area with a distinct type of vegetation that is medium green in color has many more medium green colored butterflies than either light or dark green butterflies and you notice that it is much easier to detect either light or dark green colored butterflies than medium green colored butterflies.
