Genetic Archaeology Research & News

New branch added to European family tree (10/1/2014)

Previous work suggested that Europeans descended from two ancestral groups: indigenous hunter-gatherers and early European farmers. This new study shows that there was also a third ancestral group, the Ancient North Eurasians, who contributed genetic material to almost all present-day Europeans. The research also reveals an even older lineage, the Basal Eurasians. ...> Full Article


Slimy fish and the origins of brain development (9/30/2014)

Slimy fish and the origins of brain developmentLamprey -- slimy, eel-like parasitic fish with tooth-riddled, jawless sucking mouths -- are rather disgusting to look at, but thanks to their important position on the vertebrate family tree, they can offer important insights about the evolutionary history of our own brain development, suggests a recent study done at Caltech. ...> Full Article


Natural born killers: Chimpanzee violence is an evolutionary strategy (9/29/2014)

Man's nearest relatives kill each other in order to eliminate rivals and gain better access to territory, mates, food or other resources -- not because human activities have made them more aggressive. ...> Full Article


Iberian pig genome remains unchanged after 5 centuries (9/28/2014)

A team of Spanish researchers have obtained the first partial genome sequence of an ancient pig. Extracted from a sixteenth century pig found at the site of the Montsoriu Castle in Girona, the data obtained indicates that this ancient pig is closely related to today's Iberian pig. Researchers also discard the hypothesis that Asian pigs were crossed with modern Iberian pigs. ...> Full Article


Counting fish teeth reveals regulatory DNA changes behind rapid evolution, adaptation (9/27/2014)

Counting fish teeth reveals regulatory DNA changes behind rapid evolution, adaptationThreespine sticklebacks, small fish found around the globe, undergo rapid evolutionary change when they move from the ocean to freshwater lakes, losing their armor and gaining more teeth in as little as 10 years. UC Berkeley biologist Craig Miller shows that this rapid change results not from mutations in functional genes, but changes in regulatory DNA. He pinpoints a gene that could be responsible for teeth, bone or jaw deformities in humans, including cleft palate. ...> Full Article


Human faces are so variable because we evolved to look unique (9/26/2014)

Human faces are so variable because we evolved to look uniqueWhy are human faces so variable compared to other animals, from lizards and penguins to dogs and monkeys? Two UC Berkeley scientists, Michael Nachman and postdoctoral fellow Michael Sheehan, analyzed human faces and the genes that code for facial features and found a high variability that could only be explained by selection for variable faces, probably because of the importance of social interactions in human relationships and the need for humans to be recognizable. ...> Full Article


How learning to talk is in the genes (9/25/2014)

Researchers have found evidence that genetic factors may contribute to the development of language during infancy. ...> Full Article


Gibbon genome and the fast karyotype evolution of small apes (9/15/2014)

LSU's Mark Batzer, LSU Boyd Professor and Dr. Mary Lou Applewhite Distinguished Professor, along with research assistant professor Miriam Konkel and research associate Jerilyn Walker contributed to an article featured on the cover of the scientific journal Nature. The LSU researchers contributed to the analysis of the mobile elements in the gibbon genome. This included the characterization of the mobile genetic element called LAVA. ...> Full Article


Non-dominant hand vital to the evolution of the thumb (9/14/2014)

New research from biological anthropologists at the University of Kent has shown that the use of the non-dominant hand was likely to have played a vital role in the evolution of modern human hand morphology. ...> Full Article


Sloths are no slouches when it comes to evolution (9/13/2014)

Today's sloths might be known as slow, small animals, but their ancestors developed large body sizes at an amazing rate, according to an evolutionary reconstruction published today in the open access journal BMC Evolutionary Biology. The fast rate of change suggests that factors such as environmental conditions, or competition with other species must have strongly favored the bigger sloths, before they died out. ...> Full Article


Mapping the DNA sequence of Ashkenazi Jews (9/12/2014)

Mapping the DNA sequence of Ashkenazi JewsResearchers have created a data resource that will improve genomic research in the Ashkenazi Jewish population and lead to more effective personalized medicine. The team of experts from Columbia Engineering and 10 other labs in the NYC area and Israel focused on the Ashkenazi Jewish population because of its demographic history of genetic isolation and the resulting abundance of population-specific mutations and prevalence of rare genetic disorders. The study was published on Nature Communications. ...> Full Article


A single evolutionary road may lead to Rome (9/11/2014)

New research by Michigan State University biologist Jason Gallant, Boston University biologist Sean Mullen, and their collaborators, suggests that when it comes to evolving some traits -- especially simple ones -- there may be a shared gene that's the source. The researchers were able to pinpoint the single gene responsible for two different families of butterflies' flashy markings. ...> Full Article


Sequencing of 5 African fishes reveals diverse molecular mechanisms underlying evolution (9/8/2014)

In an effort to understand the molecular basis of adaptation in vertebrates, researchers sequenced the genomes and transcriptomes of five species of African cichlid fishes. A research team led by scientists at the Broad Institute of MIT and Harvard uncovered a variety of features in the cichlid genomes that enabled the fishes to thrive in new habitats and ecological niches within the Great Lakes of East Africa. ...> Full Article


Extinctions during human era worse than thought (9/7/2014)

The gravity of the world's current extinction rate becomes clearer upon knowing what it was before people came along. A new estimate finds that species die off as much as 1,000 times more frequently nowadays than they used to. That's 10 times worse than the old estimate of 100 times. ...> Full Article


Maternal low protein diet promotes diabetic phenotypes in offspring (9/6/2014)
