How Europeans evolved white skin

Science

How Europeans evolved white skin

ST. LOUIS, MISSOURI—Most of us think of Europe as the ancestral home of white people. But a new study shows that pale skin, as well as other traits such as tallness and the ability to digest milk as adults, arrived in most of the continent relatively recently. The work, presented here last week at the 84th annual meeting of the American Association of Physical Anthropologists, offers dramatic evidence of recent evolution in Europe and shows that most modern Europeans don’t look much like those of 8000 years ago.
The origins of Europeans have come into sharp focus in the past year as researchers have sequenced the genomes of ancient populations, rather than only a few individuals. By comparing key parts of the DNA across the genomes of 83 ancient individuals from archaeological sites throughout Europe, the international team of researchers reported earlier this year that Europeans today are a mix of the blending of at least three ancient populations of hunter-gatherers and farmers who moved into Europe in separate migrations over the past 8000 years. The study revealed that a massive migration of Yamnaya herders from the steppes north of the Black Sea may have brought Indo-European languages to Europeabout 4500 years ago.

Immortality by 2045
The onset of the 21st century will be an era in which the very nature of what it means to be human will be both enriched and challenged, as our species breaks the shackles of its genetic legacy, and achieves inconceivable heights of intelligence, material progress, and longevity. The paradigm shift rate is now doubling every decade, so the twenty-first century will see 20,000 years of progress at today’s rate.

Heroes of Color - Episode 2 / Gaspar Yanga






Published on May 20, 2016
Gaspar Yanga is known as one of the first black liberators in the Americas by leading one of the most successful slave rebellions. After being forced into slavery on the sugar plantations in Veracruz, Mexico, he escaped around 1570. Gaspar and his followers headed into the mountainous terrain of Veracruz where they flourished unchallenged for nearly 30 years. His group constantly fended off Spanish military attacks. Years later, he was officially awarded land under a treaty.

Latin American Revolutions: Crash Course World History #31





Published on Aug 23, 2012
In which John Green talks about the many revolutions of Latin America in the 19th century. At the beginning of the 1800s, Latin America was firmly under the control of Spain and Portugal. The revolutionary zeal that had recently created the United States and had taken off Louis XVI's head in France arrived in South America, and a racially diverse group of people who felt more South American than European took over. John covers the soft revolution of Brazil, in which Prince Pedro boldly seized power from his father, but promised to give it back if King João ever returned to Brazil. He also covers the decidedly more violent revolutions in Mexico, Venezuela, and Argentina. Watch the video to see Simón Bolívar's dream of a United South America crushed, even as he manages to liberate a bunch of countries and get two currencies and about a thousand schools and parks named after him.
