User: The finches that Darwin studied differed in the shape of their beaks. According to Darwin, the finches probably: A. all had a common ancestor B. were born with identical beaks C. were descended from similar birds in Africa D. ate the same diet

Weegy: The answer is (A) ... but the wording implies that Darwin *concluded* common ancestry from the differences in their beaks ... which would be totally illogical. Darwin concluded common ancestry from other information not contained in the question ... [ like the geography of the islands relative to the mainland of South America, and the birds he found on the mainland, and the unique match of bird-beak to the vegetation on each island, and the records he kept of which finches were found on each island. This "teaching by multiple choice" is just a HORRIBLE way to get completely confused. ]
