Denisovans Conclusively Found Outside Denisova Cave For 1st Time

Denisovan mitochondrial DNA which was found in the layers of sediments in Baishiya Karst Cave on the Tibetan Plateau have been dated. Mitochondrial DNA, typically inherited from the mother, provides a narrower view of a population’s evolutionary past than nuclear DNA, which is inherited from both parents. No nuclear DNA has yet been found in the Baishiya Karst Cave, which is located some 1,700 miles to the northwest of Siberia’s Denisova Cave, where Denisovan remains were first identified. The new dating suggested that Denisovans first settled on the Tibetan Plateau some 100,000 years ago. Then they returned again 60,000 years ago. Because homo sapiens arrived in the region 40,000 years ago, and Denisovan DNA was found in layers dated to between 50,000 and 30,000 years ago, the Denisovans may have encountered our ancestors. The new, more reliable proof that Denisovans were on the Tibetan plateau suggests that they were relatively widespread across Eurasia.

Mummified Incan Llama Sacrifices Rediscovered

A team has found the naturally mummified remains of five young llamas thought to have been sacrificed by the Inca some 500 years ago at Tambo Viejo, an archaeological site on the coast of Peru. The animals had been prepared for the afterlife. They wore colorful string necklaces and earrings, and had been decorated using red paint and the feathers of tropical birds attached to wooden sticks. The five llamas were found under two buildings. One brown llama and three white ones were found beneath the clay floors of one building, in an area disturbed by looters. A single brown llama was found under the floor of a second building. “The adornments suggest that the offerings were very special,” said Lidio Valdez of the University of Calgary. “Indeed, historical records indicate that brown llamas were sacrificed to the creator Viracocha, while white llamas to the sun, the Inca main deity.”

African-Americans Voting After Passage of Voting Rights Act, 1965

Published by LIFE magazine. The 1965 Voting Rights Act was gutted in 2013 by the US Supreme Court, resulting in voter suppression in many American states, especially southern ones.

The oldest flamingo on record was Greater, who lived to the great old age of 83 in Australia. Since flamingos usually live just 20 to 30 years, Greater lived the equivalent of 300 human years!

Mark Twain, the famous American writer, hated the US Postal Service. He called the cost of sending letters to England "highway robbery" and thanks to his many public comments, even scored a meeting with Britain’s Postmaster General in an effort to makes overseas shipments more affordable.

Q: Why are South American animals smaller than animals on other continents?

A: Smaller animals can more easily navigate dense rainforests, like what covers most of South America. An easy comparison is deer. South American deer have evolved to have narrower racks of antlers, compared to their closest relatives in North America.

This may be the largest bird to ever fly. It is a pelagornithid, a group of ancient avians with spikey beaks, that included some of the largest flying birds of all time with wingspans double that of modern albatrosses. Members of this family first evolved 52 million years ago in Antarctica and quickly diversified till pelagornithids covered the globe’s oceans. This was actually why it took so long to identify pelagornithids as a single family: various pelagornithid species’ fossils were literally found all around the world. Sadly their last descendants died out around 2 million years ago.
