Question

The study of the body structures of the ostrich,emu and rhea shown here is an example of  ____. 
A)morphological divergence 
B)comparative morphology 
C)anatomical convergence 
D)biogeography 
E)radiometric dating

Quizplus · Accepted Answer

The study of the body structures of different organisms to identify similarities and differences is known as comparative morphology. In this case, the body structures of ostriches, emus, and rheas are being compared and studied, making (B) the correct answer. Morphological divergence refers to the differences that arise between related species over time. Anatomical convergence is when different organisms evolve similar body structures due to similar selective pressures. Biogeography studies the distribution of organisms over space and time while radiometric dating is a method used to determine the age of rocks or fossils.
