In archaeology, as in the physical sciences,new discoveries frequently undermine accepted findings and give rise to new theories. This trend can be seen in the reaction to the recent discovery of a set of 3.3-million-year-old fossils in Ethiopia, the remains of the earliest well-preserved child ever found. The fossilized child was estimated to be about 3 years old at death, female, and a member of the Australopithecus afarensis species. The afarensis species, a major human ancestor, lived in Africa from earlier than 3.7 million to 3 million years ago. "Her completeness, antiquity and age at death make this find of unprecedented importance in the history of paleo-anthropology," said Zeresenay Alemseged, a noted paleo-anthropologist. Other scientists said that the discovery could reconfigure conceptions about the lives and capacities of these early humans.
Prior to this discovery, it had been thought that the afarensis species had abandoned the arboreal habitat of their ape cousins. However, while the lower limbs of this fossil supported findings that afarensis walked upright, its gorilla-like arms and shoulders suggested that it retained the ability to swing through trees. This has initiated a reexamination of many accepted theories of early human development. Also, the presence of a hyoid bone, a rarely preserved bone in the larynx that supports muscles of the throat, has had a tremendous impact on theories about the origins of speech. The fossil bone is primitive and more similar to that of apes than to that of humans, but it is the first hyoid found in such an early human-related species.
The passage quotes Zeresenay Alemseged in order to
(A) provide evidence to qualify the main idea of the first paragraph
(B) question the claims of other scientists
(C) provide evidence to support the linguistic abilities of the afarensis species
(D) provide evidence that supports the significance of the find
(E) provide a subjective opinion that is refuted in the second paragraph
Pls explain your pick - esp why not A
