About thirteen different species of finches inhabit the Galápagos Islands today, all descendants of a common ancestor from the South American mainland that arrived a few million years ago. Genetically, there are four distinct lineages, but the thirteen species are currently classified among three genera. The first lineage to diverge from the ancestral lineage was the warbler finch (genus Certhidea). Next to diverge was the vegetarian finch (genus Camarhynchus), followed by five tree finch species (also in genus Camarhynchus) and six ground finch species (genus Geospiza). If the six ground finch species have evolved most recently, then which of these is the most logical prediction?

To estimate the number of foxes in an area, a researcher conducted a mark-recapture survey. In the first survey, he caught and marked N number of foxes. In his second survey a week later, he caught 120 foxes of which 90 were unmarked (recaptures). If you are told that the actual number of foxes in this area is 400, what is value of N in this area?
