This looks interesting: Mum’s a Neanderthal, Dad’s a Denisovan: First discovery of an ancient-human hybridGenetic analysis uncovers a direct descendant of two different groups of early humans. Link: www.nature.com/articles/d41586-018-06004-0The article notes that some of these pairing between the related groups might have resulted in infertile children ( between neanderthals and Denisovans), but the article also notes that all non African humans carry traces of Neanderthal DNA. A national geographic article notes that 'scientists found genetic overlap between the Denisovan genome and that of some present-day east Asians, and, in particular, a group of Pacific Islanders living in Papua New Guinea, known as the Melanesians. It appears the Denisovans contributed between 3 to 5 percent of their genetic material to the genomes of Melanesians. Scientists think that the most likely explanation is that Denisovans living in eastern Eurasia interbred with the modern human ancestors of Melanesians. When those humans crossed the ocean to reach Papua New Guinea around 45,000 years ago, they brought their Denisovan DNA over with them.' genographic.nationalgeographic.com/denisovan/It seems that both Neanderthals and Denisovans came out of Africa much earlier than 'modern' humans, Neanderthals perhaps contributing something of their DNA to Western Asians and Europeans, and Denisovans to east Asians and Pacific Islanders to put it in an oversimplified way. 'According to one theory, Neanderthals, Denisovans, and modern humans are all descended from the ancient human Homo heidelbergensis' Maybe we are all just a mix of Neanderthal, Denisovan and Homo Sapiens.

September 10th is the 536th anniversary of the death of Federico da Montefeltro the original Renaissance man. An illegitimate son of the lord of Urbino, he became a successful condottiere and Duke of Urbino. He used the wealth he earned as a mercenary to establish one of the largest libraries and most intellectually stimulating courts in Europe. Here is a nice article about his nose:

I am kind of reminded of REH's 'Worms of the Earth', especially after reading these lines from the above article. 'Most are not much larger than big wormholes - just 70cm wide - just wide enough for a person to wriggle along but nothing else.'

Research indicates that humans have been brewing beer far longer than was previously thought—for up to 13,700 years, reinforcing the idea that beer was critical to the development of agriculture, perhaps more so than bread.

Peru child sacrifice discovery may be largest in history www.abc.net.au/news/2018-04-28/140-children-killed-in-ancient-child-sacrifice-in-peru/9706926'Archaeologists in northern Peru say they have found evidence of what could be the world's largest single case of child sacrifice The pre-Columbian burial site, known as Las Llamas, contains the skeletons of 140 children who were between the ages of five and 14 when they were ritually sacrificed during a ceremony about 550 years ago, experts who led the excavation said. The site, located near the modern day city of Trujillo, also contained the remains of 200 young llamas apparently sacrificed on the same day. The burial site was apparently built by the ancient Chimu empire. It is thought the children were sacrificed as floods caused by the El Nino weather pattern ravaged the Peruvian coastline.'

that is great news. so many archaeologists have been 'colour blind' for centuries.

Kail! You demonic Berserker, you! I was getting ready to post this same fascinating find! I love ship wrecks.
