main idea: recent discovery in e challenged the long-held theory on capability of humans and the details of findings are introduced
structure:
p1. the finding of 3,3 million-year-old female child fossils is unprecedented important for new theory in archogilogic history
-place where it was founded, age of death, axx species
-completeness and antiquity
p2.structure of the fossil changed the long-held view
-lower limbs support that they can stand walking
-original view: no abrobeal ability in axx species, after: long arms to hang
-new finding: the presence of hyoid bone affected the concept of origin of speech and the first found in such an early human-related fossil
-more like apes than human
new words:
noted: 著名的
antiquity: 年代久远
hyoid: 舌骨 |
