    National Public Radio recently interviewed Trinity Western University biologist Dennis Venema, who stated his belief that humans did not descend from Adam and Eve.1 Venema, an evangelical evolutionist, claimed that genetics studies show "there is no way we can be traced back to a single couple."2 Do the data really contradict the biblical account of human history? "Given the genetic variation of people today, [Venema] says scientists can't get that [starting] population size below 10,000 people at any time in our evolutionary history," NPR reported.2 But this claim fails for three reasons. First, it relies on the presumption of "evolutionary...

    A Native American man in Montana has what may be the oldest DNA native to the Americas, according to news reports. After getting his DNA tested, Darrell "Dusty" Crawford learned that his ancestors were already in the Americas about 17,000 years ago, according to the Great Falls Tribune, a Montana newspaper.

    Full title: Four ancient skulls unearthed in Mexico suggest that North America was a melting pot of different peoples and cultures 10,000 years ago The first humans to settle in North America were more diverse than previously believed, according to a new study of skeletal fragments. US scientists analysed four skulls recovered from caves in Mexico that belonged to humans that lived sometime between 9,000 to 13,000 years ago. The researchers were surprised to find a high level of diversity, with the skulls ranging in similarity to that of Europeans, Asian and ...

    After a bone marrow transplant, a man with leukemia found that his donor’s DNA traveled to unexpected parts of his body. A crime lab is now studying the case. Three months after his bone marrow transplant, Chris Long of Reno, Nev., learned that the DNA in his blood had changed. It had all been replaced by the DNA of his donor, a German man he had exchanged just a handful of messages with. He’d been encouraged to test his blood by a colleague at the Sheriff’s Office, where he worked. She had an inkling this might happen. It’s the goal...

    A new genetic study carried out at the University of Helsinki and the University of Turku demonstrates that, at the end of the Iron Age, Finland was inhabited by separate and differing populations, all of them influencing the gene pool of modern Finns. The study is so far the most extensive investigation of the ancient DNA of people inhabiting the region of Finland. In the study, genes were investigated from archaeological bone samples of more than one hundred individuals who lived between the 4th and 19th centuries AD. Most of the samples originated in the Iron Age and the Middle...

    What would it have been like to meet a Neandertal? Researchers have hypothesized answers for decades, seeking to put flesh on ancient bones. But fossils are silent on many traits, from hair and skin color to speech and personality. Personality will have to wait, but in a paper published online in Science this week (www.sciencemag.org/cgi/content/abstract/1147417), an international team announces that it has extracted a pigmentation gene, mc1r, from the bones of two Neandertals. The researchers conclude that at least some Neandertals had pale skin and red hair, similar to some of the Homo sapiens who today inhabit their European homeland....

    EurekAlert! ^ | Wednesday, June 26, 2019 | Max Planck Institute for Evolutionary Anthropology
    Researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have retrieved nuclear genome sequences from the femur of a male Neandertal discovered in 1937 in Hohlenstein-Stadel Cave, Germany, and from the maxillary bone of a Neandertal girl found in 1993 in Scladina Cave, Belgium. Both Neandertals lived around 120,000 years ago, and therefore predate most of the Neandertals whose genomes have been sequenced to date. By examining the nuclear genomes of these two individuals, the researchers could show that these early Neandertals in Western Europe were more closely related to the last Neandertals who lived in the...

    Even single-celled organisms desire partners every now and then. Leishmania—single-celled parasites that cause infections of the skin and internal organs—have long been known to multiply asexually, like bacteria. But occasionally, researchers have found hybrid parasites that carry genetic material from more than one strain—or even more than one species—of Leishmania, suggesting that some kind of genetic mixing is going on.Now, researchers at Washington University School of Medicine in St. Louis and the National Institutes of Health (NIH) have found that the hybrid Leishmania parasites can mate with one another to produce fertile offspring that carry genes from both parents—signs of...

    Geneticists have added an edge to a 2,500-year-old debate over the origin of the Etruscans, a people whose brilliant and mysterious civilization dominated northwestern Italy for centuries until the rise of the Roman republic in 510 B.C. Several new findings support a view held by the ancient Greek historian Herodotus — but unpopular among archaeologists — that the Etruscans originally migrated to Italy from the Near East. Though Roman historians played down their debt to the Etruscans, Etruscan culture permeated Roman art, architecture and religion. The Etruscans were master metallurgists and skillful seafarers who for a time dominated much of...

Found in Orvieto, Italy One of anthropology's most enduring mysteries - the origins of the ancient Etruscan civilisation - may finally have been solved, with a study of cattle. This culturally distinct and technologically advanced civilisation inhabited central Italy from about the 8th century BC, until it was assimilated into Roman culture around the end of the 4th century BC. The origins of the Etruscans, with their own non-Indo-European language, have been debated...

A DNA comparison of Etruscan skeletons and a sample of living Tuscans has thrown up only "tenuous genetic similarities", said lead researcher Guido Barbujani of Ferrara University . "If the Tuscans were the direct descendants of the Etruscans the DNA should be the same," said Barbujani, a genetecist who coordinated the study with Stanford University in the United States .

    Researchers tested blood and semen found on a shawl near the body of the killer's fourth victim, a woman whose mutilated body was found in September 1888. The identity of Jack the Ripper, the notorious serial killer from the late 1800s in England, may finally be known. A DNA forensic investigation published this month by two British researchers in the Journal of Forensic Science identifies Aaron Kosminski, a 23-year-old Polish barber and prime suspect at the time, as the likely killer. The "semen stains match the sequences of one of the main police suspects, Aaron Kosminski," said the study authored...

In an astonishing piece of detective work, they matched mitochondrial DNA material extracted from the tooth cavity of Britain's oldest complete skeleton with that of a 42-year-old history teacher, Adrian Targett. The genetic material showed without doubt that Targett is a direct descendant through his mother's line of the skeleton known as Cheddar Man, which was found in 1903 in caves in Cheddar Gorge...

    New research published in Science shows that our most recent common female and male ancestors could have been alive at the same time.Thousands of years ago, somewhere in Africa, lived a man who – probably – had no idea that he, among all the other men in his group, would go on to become humankind’s most recent common male ancestor. Scientists would call him “Adam.” Now, a new paper published in the journal Science significantly narrows the time during which Adam could have lived – about 120,000 to 156,000 years ago – putting him in about the same time period...

    The Book of Genesis puts Adam and Eve together in the Garden of Eden, but geneticists’ version of the duo — the ancestors to whom the Y chromosomes and mitochondrial DNA of today’s humans can be traced — were thought to have lived tens of thousands of years apart. Now, two major studies of modern humans’ Y chromosomes suggest that ‘Y-chromosome Adam’ and ‘mitochondrial Eve’ may have lived around the same time after all. When the overall population size does not change (as is likely to have happened for long periods of human history), men have, on average, just one...

    Our ancestors bred with other species in the Homo genus, according to a study published today in the Proceedings of the National Academy of Sciences1. The authors say that up to 2% of the genomes of some modern African populations may originally come from a closely related species. Palaeontologists have long wondered whether modern humans came from a single, genetically isolated population of hominins or whether we are a genetic mix of various hominin species. Last year, an analysis comparing the Neanderthal genome sequence to that of modern H. sapiens showed that some interbreeding did take place between the two...
