Ecologists have studied the galapagos islands for a long time because of the diversity of the populations they possess. it is thought that small colonies of finches emerged on each of these small islands, each small population carrying only certain alleles of the parent population. over time, the emerging populations varied greatly from one another, leading to the development of new species. which mechanism of speciation best describes this scenario?
is d

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.
