Today's Practice GMAT Question:

Archeologist: The discovery of chicken bones in a recently excavated Incan settlement, dating between 1320 and 1410 C.E., suggests that chickens were brought to the Americas by Polynesians before introduction by the Spaniards. It is also possible that contamination caused the specimens to appear older than they actually are. To settle this, scientists sequenced DNA from the ancient chicken bones and from Polynesian chickens and found that they share a genetic signature. A later genetic study revealed that the same signature is found in chickens from throughout Europe and Asia.
Which of the following, if true, most helps to explain the findings of the later study?
(A) European explorers in the 16th century collected live animals from throughout the Americas and returned them to Europe for study and breeding.
(B) The Incas did not raise chicken for food.
(C) DNA sequencing is a reliable method of identifying the migration of species from one continent to another, even over a period of centuries.
(D) In diaries of Asian expeditions, European explorers refer to feasting on a game bird that may be related to the Polynesian chicken.
(E) The Spaniards did not introduce chickens to the Americas until at least 1500 C.E.
