Which of the following is the best environment in which to observe impacts of the founder effect?
a. the north american great plains
b. the amazon rainforest
c. small pacific islands
d. deserts

I just took the test and the answer was C. Small Pacific Islands.

d. it spread christianity. i just took the test and got it right.

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
