Science Daily: Neanderthals may have had a lower threshold for pain "Pain is mediated through specialized nerve cells that are activated when potentially harmful things affect various parts of our bodies. These nerve cells have a special ion channel that has a key role in starting the...

A new paper confirms that Native pre-Columbian Americans from Colombia migrated to Eastern Polynesia 800 years ago and intermingled with the expanding Polynesian population of Austronesian origin. Native American gene flow into Polynesia predating Easter Island settlement, Ioannidis et al...

Role of STING complex in differential retrograde signaling in cybrids with K versus H haplogroup mtDNA Abstract Mitochondrial (mt) DNA haplogroups, defined by specific single nucleotide polymorphism (SNPs) patterns, represent populations of diverse geographic origins and may play a role in...

Nature: Incest uncovered at the elite prehistoric Newgrange monument in Ireland "The huge, elaborate, 5,000-year-old tomb at Newgrange, Ireland, is thought to have been built for a powerful elite. DNA of a man buried there reveals a case of incest. Was this a strategy to maintain a dynastic...

I finally got around to create a map about the Bell Beaker phenomenon. It was a complex task as there are already many maps out there, but few agree on the distribution of the Beaker and the main hubs of this vast commercial network. Some maps show arrows of the probable diffusion of the beakers...

The great American inventor Thomas Alva Edison (1847-1931) appears to have belonged to R1b-L151>S1194>S1200>S14328>SZ5489>Y28597>S10242 according to the Edison Y-DNA project (lineage 1). He is descended from John Edison and Sarah Ogden from the Netherlands. This branch of R1b is found in...

The Lee family descended from Richard Lee I (1617–1664), who emigrated from Shropshire, England to Virginia, played an important role in American history. Based on the results from the Lee Surname DNA Research Project, descendants of Richard Lee I and his wife Anne Constable (Subgroup 21)...

The influential Randolph family of Virginia belongs to R1b-P312>Z39300 (aka PH2278) based on the results from the Randolph/Randall/Randle/Randol Surname Group (Albemarle County group). The family contributed numerous politicians, statesmen and military officers in the course of U.S. history...

Benjamin Franklin, a polymath and one of the Founding Fathers of the United States, whose head has featured on the $100 bills since 1914, is a probable member of haplogroup R1b-U106>Z18>DF95 according to the results from the Franklin Family Y-DNA Project. His family hailed from the small...

Two US presidents, George H.W. Bush and George W. Bush apparently belong to haplogroup R1b DF27>Z196>Z209> CTS4065>S16864 based on the results from the Bush Surname Project. I ran the haplotype in NevGen's haplogroup predictor to determine the subclade. They descend from Reynold Bush (1600-1686)...

I have embarked on an ambitious project: attempting to determine the haplogroups of ancient Roman gentes based on the modern European surnames that belong to ancient Latin haplogroups. It may seem like an impossible quest because there is no guarantee that any ancient Roman surname survives to...

The Antonio et al. (2019) paper on Ancient Rome was released 2 and a half months ago, so I am coming a bit late for the analysis, but I had been busy before. Using the Dodecad K12b data provided by Jovialis, I created a table of the 11 Iron Age samples from this study. ID Date Y-DNA...

Hello, I'm new to Eupedia as you can probably tell. I've always been interested in genetics and anthropology but for some reason never managed to make an account. Anyways, I recently took a test with 23andme. The test was very useful and even connected me with a few 2nd cousins. But, what I'm...

WASHINGTON, Feb 18 (Reuters) - The great white shark, one of the most fearsome predators in the world's oceans in both fact and fiction, is a formidable creature -- right down to its genes. Scientists on Monday said they have decoded the genome of Earth's largest predatory fish, detecting...

Dear DNA test-takers, My name is Maria and I am a Master's student in the Netherlands. The course I'm doing is called Intercultural Communication in which I study diversity and all aspects involved. I'm currently in the process of writing a thesis about the effects of DNA- testing on the...

Personally, I think the title of the episode is misleading. I think the title of this thread would be a more accurate description of this insitome podcast. They talk about how some genetic influences on phenotype may have led to some legends and myths. It's pretty interesting, and I'd suggest...

The quality of gene sequencing has improved so much and its price has fallen so far that a start-up now says it can offer the service for free. Nebula Genomics aims to sequence a customer’s entire genome, according to the company’s chief scientific officer Dennis Grishin. In contrast, current...

How to see the problem of genetically modified food? Is genetically modified food safe? What are the harms to humans? Which countries currently import the most GM crops? img: credit

Hi I have just found this study: https://www.researchgate.net/figure/Distribution-of-the-Yamnaya-genetic-component-in-the-populations-of-Europe-data-taken_fig2_318751121 which shows a different map for the Yamnaya admixture than the one included in this site... interestingly, in the map here...
