Passage: Homo erectus originated in Africa about 2 million years ago and spread to Eurasia; modern humans appeared about 200,000 years ago. Fossils of these two species are distributed in China. For example, the "Peking Man" unearthed from the ancient strata in Zhoukoudian, Beijing belonged to Homo erectus; the "Mountain caveman" in the strata a few years ago belonged to modern humans. Research on contemporary Chinese populations has found that the paternally inherited Y chromosomes all originated from Africa, and the origin date was 8.9 10,000 to 35,000 years ago; maternally inherited mitochondrial DNA originates from Africa, and the origin time is within 100,000 years; no genetic components of Homo erectus have been detected.
Question: If the above statement is true, which of the following hypothesis is most supported?
A. A.Descendants of "Peking Man" may be extinct, the ancestors of contemporary Chinese came to Asia from Africa about 100,000 years ago
B. B.Homo erectus and modern humans in China came from the African continent respectively, and their hybrid descendants are the ancestors of contemporary Chinese people
C. C.The "Mountain caveman" in Zhoukoudian, Beijing evolved from the "Beijing Man"
D. D.Contemporary Chinese are descendants of Homo erectus who spread from Africa to Eurasia 2 million years ago
