Neanderthals bred with humans 100,000 YEARS earlier than first thought, scientists say - as they discover skeleton of five-year-old crossbreed

Daily Mail - Science & tech

Neanderthals bred with our human ancestors 100,000 years earlier than previously thought, according to a new study. Experts have discovered that a five–year–old child who lived 140,000 years ago had parents from both species. Their fossil – likely a female – was first unearthed 90 years ago in the Skhul Cave on Mount Carmel in what is now northern Israel. A team from Tel Aviv University and the French Centre for Scientific Research conducted a series of advanced tests on the remaining bones, including a CT scan of the skull. 'Genetic studies over the past decade have shown that these two groups exchanged genes,' said lead author Professor Israel Hershkovitz.


Scientists reveal exactly what a neanderthal human hybrid would look like

Daily Mail - Science & tech

It has been over 40,000 years since the last of the Neanderthals, our ancient human cousins, disappeared from the Earth. But from the shape of your nose to whether someone is an early riser, Neanderthal genes are still shaping many of our lives today. Starting from around 250,000 years ago, ancient homo sapiens and Neanderthals met, lived alongside each other, and often had children together. Now, MailOnline has asked leading paleoanthropologists to reveal what those hybrid children would have looked like. Scientists believe that hybrid children would inherit traits from both of their parents.


The 5 times humans almost went EXTINCT - as scientists reveal the date our species could finally be wiped out

Daily Mail - Science & tech

With eight billion people now walking the Earth, the thought of humans going extinct anytime soon seems rather unlikely. But even if our population is booming today, it hasn't always been that way. That's because there have been at least five occasions throughout history where the human race has been in danger of dying out, not least because of the eruption of a supervolcano 70,000 years ago that almost sent us the same way as the dinosaurs. But what happened on the other occasions? And how close did we really come to not existing?


Portrait of an 8-year-old Neanderthal boy who lived more than 30,000 years ago is REVEALED

Daily Mail - Science & tech

The face of an eight-year-old Neanderthal boy who died more than 30,000 years ago has been reconstructed by scientists who used a skull initially found in the Teshik-Tash cave in Uzbekistan in 1938. The portrait is the first three-dimensional restoration of a Neanderthal skull fossil, which reveals the young boy had a small, turned-up nose that sunk into his face. The fossil is the first Neanderthal fossil discovered in Asia and the only complete Asian Neanderthal skull fossil preserved so far. The team, led by China's Jilin University and Russia's Moscow State University, believes that the restoration shows the facial shape of prehistoric humans in Eurasia and displays the morphological characteristics of Neanderthals in Central Asia. The skull, dubbed Teshik-Tash 1, was found in a shallow pit inside the cave, along with five pairs of Siberian ibex horn cores and bird skeletons.


Nicolas Babin disruptive week about Artificial Intelligence - November 29th 2021 - Babin Business Consulting

#artificialintelligence

I am regularly asked to summarize my many posts. I thought it would be a good idea to publish on this blog, every Monday, some of the most relevant articles that I have already shared with you on my social networks. Today I will share some of the most relevant articles about Artificial Intelligence and in what form you can find it in today's life. I will also comment on the articles. AI is everywhere, but how does it make decisions, balance society, and remain free from bias? These days, technology is making leaps in an unprecedented manner.


Artificial Intelligence Has Found an Unknown 'Ghost' Ancestor in The Human Genome

#artificialintelligence

Nobody knows who she was, just that she was different: a teenage girl from over 50,000 years ago of such strange uniqueness she looked to be a'hybrid' ancestor to modern humans that scientists had never seen before. Only recently, researchers have uncovered evidence she wasn't alone. In a 2019 study analysing the complex mess of humanity's prehistory, scientists used artificial intelligence (AI) to identify an unknown human ancestor species that modern humans encountered – and shared dalliances with – on the long trek out of Africa millennia ago. "About 80,000 years ago, the so-called Out of Africa occurred, when part of the human population, which already consisted of modern humans, abandoned the African continent and migrated to other continents, giving rise to all the current populations", explained evolutionary biologist Jaume Bertranpetit from the Universitat Pompeu Fabra in Spain. As modern humans forged this path into the landmass of Eurasia, they forged some other things too – breeding with ancient and extinct hominids from other species. Up until recently, these occasional sexual partners were thought to include Neanderthals and Denisovans, the latter of which were unknown until 2010.


Neanderthals ate seafood including crabs, clams, oysters and dolphins

Neanderthals fed regularly on mussels, fish and other omega-3-rich marine life including seals, which likely impacted their cognitive abilities, a new study claims. Archaeological digs along the Portuguese coast reveal the evidence that our cavemen ancestors had as much fondness for seafood as modern humans today. Both Neanderthals and early Homo sapiens tucked into'surf and turf', from molluscs, crabs, fish, waterfowl and dolphins to horse, goat and red deer, as well as pine nuts. The findings are based on ancient remains in the cave of Figueira Brava, Portugal, dating to roughly 106,000-86,000 years ago – when Neanderthals settled in Europe. Figueira Brava is 18.6 miles (30km) south of Lisbon on the slopes of the Serra da Arrábida, a natural park facing south, about a 45-minute drive from Lisbon'Pretty much every potential source of food that existed in the environment they [Neanderthals] exploited and used it,' said Professor João Zilhão, an expert in palaeolithic archaeology at the University of Barcelona.


Deep Learning on Neanderthal Genes

#artificialintelligence

This is the seventh post of my column Deep Learning for Life Sciences where I give concrete examples of how Deep Learning can already now be applied in Computational Biology, Genetics and Bioinformatics. In the previous posts, I demonstrated how to use Deep Learning for Ancient DNA, Single Cell Biology, OMICs Data Integration, Clinical Diagnostics and Microscopy Imaging. Today we are going to dive into the exciting History of Human Evolution and learn that it is straightforward to borrow methodology from the Natural Language Processing (NLP) and apply it to Human Population Genetics in order to infer regions of Neanderthal introgression in modern human genomes. When ancestors of Modern Humans migrated out of Africa 50 000 - 70 000 years ago, they encountered Neanderthals and Denisovans, two groups of ancient hominins that populated Europe and Asia at that time. We know that Modern Humans interbred with both Neanderthals and Denisovans since there is evidence of the presence of their DNA in genomes of Modern Humans of non-African origin.


Researcher stumbles upon mysterious 5,000-year-old paintings depicting arrows and human-like figures

Daily Mail - Science & tech

A collection of 5,000-year-old cave paintings depicting various figures and symbols has been discovered in Spain. The drawings were discovered in the rocky area of San Juan, near the town of Albuquerque in the province of Badajoz in western Spain. They are around 4 inches in length and include some anthropomorphic figures, as well as an arrow and other symbols, according to Spanish daily newspaper La Vanguardia. The doodlings were discovered by Agustín Palomo, an historic researcher who lives locally to the caves, while he was looking for a type of tomb known as a Dolmen. Mr Palomo immediately recognised their significance, given their location not far from two other well-known sets of cave drawings - 'Risco de San Blas', of the Sierra de la Carava and those of Azagala - the latter of which were only discovered around 20 years ago.
