It isn't hard to explain... remnants of a former advanced civilization, spread throughout the world after a cataclysm, still remembered the basic techniques for making alcoholic drinks.

Chemical tests on ancient fragments of broken pottery show that Chinese villagers were brewing alcoholic drinks as far back as 7000 BC. That beats the previous record for the oldest evidence of brewing, found in Iran and dated at about 5400 BC. Why brewing developed nearly simultaneously in east Asia and the middle east is something “we haven't resolved yet", McGovern told New Scientist. "The expanse of central Asia in between would seem to preclude any direct connection," he says, but more research may show links - or a common origin.td>

A whale with a mysterious singing voice that matches no other has been spotted cruising the ocean alone every autumn and winter since 1992, singing at a frequency of 52 hertz. Other whales sing at between 15 and 20 hertz. The routes taken by the mammal also do not match migration patterns of other species. But US marine biologist Mary Anne Daher said the calls were clearly that of a baleen, the family that includes blue and humpback whales. She doubts the whale belongs to a new species, although no similar call has been anywhere else, New Scientist reported.

I thought this was interesting for the frequency/migration difference and whether it has anything to do with the magnetic field changes
