Question

Quizplus · Accepted Answer

The discovery of Ardi (Ardipithecus ramidus) in 2009 does not replace Lucy as the earliest known hominin skeleton. Lucy’s skeleton dates back to 3.2 million years ago, while Ardi’s is from 4.4 million years ago. Ardi’s discovery offers important new information about the earliest stages of hominin evolution, but it does not replace all previously known hominin fossils.

Answer: C
 Ardi stood about 4 feet tall and weighed around 110 pounds, while Lucy was slightly taller at 4 feet 3 inches but weighed less, around 65 pounds.

Answer: E
 Ardi is not the ancestor of Homo, but it is believed to have lived before the time of the australopithecines. It provides important insights into the evolution and diversification of early hominins from the common ancestor shared with chimpanzees.

Therefore, the best choices are A and C.
