What continent is home to the people considered to be earth's oldest surviving ethnic people?(以下哪个大陆是被认为地球上现存最古老的人种的发源地?)
A 北美
B 亚洲
C 澳洲
D 欧洲
E 以上都不是
解析说的是 The Aborigines of Australia are thought to have originated at least 40,000 years ago.
但非洲难道不是所有人种的最初发源地么?没有非洲的话,我觉得亚洲怎么着也比澳洲早吧.

应该是澳大利亚中的土著人种最古老吧.
