Geneticists Quotes

“Despite the passage of close to a million years since Homo erectus first sailed to Flores, however, what archaeology does not concede is that the human species could have developed and refined those early nautical skills to the extent of being able to cross a vast ocean like the Pacific or the Atlantic from one side to the other. In the case of the former, extensive transoceanic journeys are not believed to have been undertaken until about 3,500 years ago, during the so-called Polynesian expansion. And the mainstream historical view is that the Atlantic was not successfully navigated until 1492--the year in which, as the schoolyard mnemonic has it, "Columbus sailed the ocean blue."
Indeed, the notion that long transoceanic voyages were a technological impossibility during the Stone Age remains one of the central structural elements of the dominant reference frame of archaeology--a reference frame that geneticists see no reason not to respect and deploy when interpreting their own data. Since that reference frame rules out, a priori, the option of a direct ocean crossing between Australasia and South America during the Paleolithic and instead is adamant that all settlement came via northeast Asia, geneticists tend to approach the data from that perspective.”
