Question: Scientists are still debating when people started wearing clothes. Ralf Kittler, Manfred Kayser and Mark Stoneking, anthropologists at the Max Planck Institute for Evolutionary Anthropology, have conducted a genetic analysis of human body lice that suggests clothing originated quite recently, around 170,000 years ago. Body lice is an indicator of clothes-wearing, since most humans have sparse body hair, and lice thus require human clothing to survive. Their research suggests the invention of clothing may have coincided with the northward migration of modern Homo sapiens away from the warm climate of Africa, thought to have begun between 50,000 and 100,000 years ago. However, a second group of researchers using similar genetic methods estimate that clothing originated around 540,000 years ago (Reed et al. 2004. PLoS Biology 2(11): e340). For now, the date of the origin of clothing remains unresolved.[citation needed]

Question: These critics of the modern separation of church and state also note the official establishment of religion in several of the states at the time of ratification, to suggest that the modern incorporation of the Establishment Clause as to state governments goes against the original constitutional intent.[citation needed] The issue is complex, however, as the incorporation ultimately bases on the passage of the 14th Amendment in 1868, at which point the first amendment's application to the state government was recognized. Many of these constitutional debates relate to the competing interpretive theories of originalism versus modern, progressivist theories such as the doctrine of the Living Constitution. Other debates center on the principle of the law of the land in America being defined not just by the Constitution's Supremacy Clause, but also by legal precedence, making an accurate reading of the Constitution subject to the mores and values of a given era, and rendering the concept of historical revisionism irrelevant when discussing the Constitution.
Is there an answer to this question: What kind of theory is the doctrine of the Living Constitution?

Answer: progressivist

Question: Zhejiang was the site of the Neolithic cultures of the Hemudu and Liangzhu. A 2007 analysis of the DNA recovered from human remains in the archeological sites of prehistoric peoples along the Yangtze River shows high frequencies of haplogroup O1 in the Liangzhu culture, linking them to Austronesian and Tai-Kadai peoples.
Is there an answer to this question: What haplogroup did a DNA analysis of the Liangzhu culture not reveal?

Answer:
unanswerable
