DNA study links indigenous Brazilians to Polynesians

Indigenous people that lived in southeastern Brazil in the late 1800s shared some genetic sequences with Polynesians, an analysis of their remains shows. The finding offers some support for the possibility that Pacific islanders traded with South America thousands of years ago, but researchers say that the distinctive DNA sequences, or haplogroups, may have entered the genomes of the native Brazilians through the slave trade during the nineteenth century.

Most scientists agree that humans arrived in the Americas between 15,000 and 20,000 years ago, probably via the Bering land bridge linking northeastern Asia with what is now Alaska. But the precise timing and the number of ‘migration waves’ is unclear, owing largely to variations in early Americans’ physical features, says Sérgio Pena, a molecular geneticist at the Federal University of Minas Gerais in Belo Horizonte, Brazil.

One broad group of these Palaeoamericans — the Botocudo people, who lived in inland regions of southeastern Brazil — stands out, having skull shapes that were intermediate between those of other Palaeoamericans and a presumed ancestral population in eastern Asia.

Mark Twain on April Fool's Day


Google began April Fools’ Day early by unveiling some of its pranks on Sunday, which include launching a scent-based search engine and shutting down YouTube, among other fake announcements.

Users of Google Analytics reported seeing web traffic from the International Space Station Sunday afternoon. The number of astronauts allegedly visiting a user’s page totaled 41, which represents April 1, or April Fools’ Day.

Google also launched a beta product called Google Nose. Google Nose, if it were real, would allow users to search for various smells, including “wet dog,” “horse manure” and “locker room.”

Precursors of April Fools' Day include the Roman festival of Hilaria, held March 25,[2] and the Medieval Feast of Fools, held December 28,[3] still a day on which pranks are played in Spanish-speaking countries.
In Chaucer's Canterbury Tales (1392), the "Nun's Priest's Tale" is set Syn March bigan thritty dayes and two.[4] Modern scholars believe that there is a copying error in the extant manuscripts and that Chaucer actually wrote, Syn March was gon.[5] Thus, the passage originally meant 32 days after April, i.e. May 2,[6] the anniversary of the engagement of King Richard II of England to Anne of Bohemia, which took place in 1381. Readers apparently misunderstood this line to mean "March 32", i.e. April 1.[7] In Chaucer's tale, the vain cock Chauntecleer is tricked by a fox.
