Biologists have classified the elephant shrew, a small mole-like mammal, with other shrews of similar size and body shape. however, this classification has been questioned, since elephant shrews have much more well-developed eyes and ears than other animals in the shrew family and use their tongues like anteaters to feed on insects, a trait not shared with true shrews. because of their similarities to anteaters, a biologist has proposed that the elephant shrew is more closely related to anteaters than to shrews. design a plan for investigating the validity of this new hypothesis. describe your plan and include the methods and sources of material you would need to carry out your plan.

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.
