For the most part, the data fit the current thinking about human evolution. The Igbo and Yoruba peoples from the Bights of Benin and Biafra constituted roughly one-third of all enslaved Africans transported to the Americas. But scientists have “That’s the gold standard,” Dr. Sankararaman said. A small-brained hominin that could be found roaming around the South African plains 250,000 years ago, Homo naledi, is a possible but unlikely contender. The question now is who does this “ghost” DNA belong to? They later expanded into Eurasia, where they interbred with both Neanderthals and Denisovans. According to their findings, there is DNA from an unknown species of ancient hominin in about eight percent of the genetic ancestry from the West African Yoruba population. So, what has become "Yoruba or Mende DNA" in genetic studies is no more than two samples (populations) of DNA from West Africa. A mysterious "ghost population" of now-extinct ancient human-like creatures may have interbred with early humans living in West Africa, scientists say.

In the research, Arun Durvasula and Sriram Sankararaman from the Department of Human Genetics at UCLA presented a statistical method that combines diverse population genetics to identify unusual genetic codes in archaic ancestry in present-day individuals.Using this novel method, the researchers applied it to the DNA of 50 randomly selected individuals from a European population and to the DNA of 50 modern individuals of the Yoruba African population whose genomes were sequenced in the According to their findings, there is DNA from an unknown species of ancient hominin in about eight percent of the genetic ancestry from the West African Yoruba population. In 2010, a team of researchers published the first genome of a Neanderthal. There is evidence that suggests this advanced hominin population was living in Africa over 200,000 years ago. Scientists have yet to succeed at that effort, because DNA quickly degrades in the tropics. They devised a statistical method able to highlight abnormal genetic code without needing the genome of the species it was inherited from.The hotter and wetter climate on the African continent tends to destroy any preserved DNA, unlike samples of human-like species the Neanderthals and Densiovans uncovered in Europe and Asia. Population genetics. A million years ago, Africa was home to a species known as Homo erectus. but it is $250 cheaper and still get most of the other cutting-edge features found on the more expensive model.AI seems to permeate every part of its software, from the ability to answer calls for you to being able to almost perfectly predict your morning commute.Apple's new iPhone XS and XS Max go on sale on Friday - and the biggest handset Apple has ever made is also its best (and possibly unsurprisingly, its most expensive).Israeli beauty-tech firm Pollogen has launched its Geneo Personal device, which stimulates oxygen from beneath the skin's surface to give you a clearer, fresher face within minutes.Rather than cram in a plethora of new features, Apple's latest update is about boosting stability, with improvements in everything from FaceID and battery life.It's eye-wateringly expensive at $2,999, but Naim's Uniti Atom is a revelation, an integrated amplifier than makes it easy to stream music at a quality you've probably never heard before.Naim's incredible Mu-So Qb takes you back to the good old days - where the music captivates and enthralls, rather that simply being something in the background.Peloton's hi-tech bike lets you stream live and on demand rides to your home - and it's one of the best examples of fitness technology out there - at a price.It might not be a name familiar to the US market, but Naim is a legendary British brand hoping to make a splash with the American launch of its $1499 Mu:So speaker. Instead, the researchers found pieces of their DNA in the genomes of living people from West Africa.Arun Durvasula and Sriram Sankararaman, two geneticists at the University of California, Los Angeles, described this so-called ghost archaic population in The new study builds on a decade of research into ancient DNA extracted from human fossils.
