The anglo-saxon migration: New insights from genetics      (via sciencedaily.com) 

In the largest early-medieval population study to date, an interdisciplinary team consisting of geneticists and archaeologists analyzed over 400 individuals from ancient Britain, Ireland, Germany, Denmark and the Netherlands. The results show in detail one of the largest population transformations in the post-Roman world.

What ancient dung reveals about Epipaleolithic animal tending      (via sciencedaily.com) 

Tiny crystals in ancient animal dung serve as key evidence in a new analysis suggesting the possibility that hunter-gatherers at Abu Hureyra, Syria, may have tended small numbers of animals just outside their dwellings between 12,800 and 12,300 years ago.

Earliest land animals had fewer skull bones than fish -- restricting their evolution, scientists find      (via sciencedaily.com) 

The skulls of tetrapods had fewer bones than extinct and living fish, limiting their evolution for millions of years, according to a latest study.

Modern humans generate more brain neurons than Neanderthals      (via sciencedaily.com) 

The question of what makes modern humans unique has long been a driving force for researchers. Comparisons with our closest relatives, the Neanderthals, therefore provide fascinating insights. The increase in brain size, and in neuron production during brain development, are considered to be major factors for the increased cognitive abilities that occurred during human evolution. However, while both Neanderthals and modern humans develop brains of similar size, very little is known about whether modern human and Neanderthal brains may have differed in terms of their neuron production during development. Researchers now show that the modern human variant of the protein TKTL1, which differs by only a single amino acid from the Neanderthal variant, increases one type of brain progenitor cells, called basal radial glia, in the modern human brain.

Study unearths ancient reef structure high and dry on the Nullarbor Plain      (via sciencedaily.com) 

Researchers using advanced satellite imagery have discovered an ancient reef-like landform 'hidden' in plain view on the Nullarbor Plain, which has been preserved for millions of years since it first formed when the Plain was underwater.

Resolving the evolutionary history of the closest algal relatives of land plants      (via sciencedaily.com) 

Scientists use genomic data to resolve the phylogeny of zygnematophyte algae and pinpoint several emergences of multicellularity in the closest known relatives of terrestrial plants.

Medieval mass burial shows centuries-earlier origin of Ashkenazi genetic bottleneck      (via sciencedaily.com) 

In 2004, construction workers in Norwich, UK, unearthed human skeletal remains that led to a historical mystery -- at least 17 bodies at the bottom of a medieval well. Using archeological records, historical documents, and ancient DNA, British researchers have now identified the individuals to be a group of Ashkenazi Jews who may have fallen victim to antisemitic violence during the 12th century. Their findings shed new light on Jewish medical history in Europe.

The Southern Arc and its lively genetic history      (via sciencedaily.com) 

A vast paleogenetic study reveals insights on migration patterns, the expansion of farming and language development from the Caucasus over western Asia and Southern Europe from the early Copper Age until the late middle ages.

DNA analysis shows Griffin Warrior ruled his Greek homeland      (via sciencedaily.com) 

Using new scientific tools, archaeologists discovered that an ancient Greek leader known today as the Griffin Warrior likely grew up around the seaside city he would one day rule. The findings are part of three new studies that examined the ancient DNA of the Griffin Warrior and 726 other people who lived before and during the Bronze Age to learn more about their origins and movements across three continents surrounding the Mediterranean Sea.

Sahelanthropus, the oldest representative of humanity, was indeed bipedal...but that's not all!      (via sciencedaily.com) 

The modalities and date of emergence of bipedalism remain bitterly debated, in particular because of a small number of very old human fossils. Sahelanthropus tchadensis, discovered in 2001 in Chad, is considered to be the oldest representative of the humankind. The shape of its cranium suggests a bipedal station. The description of three limb bones of Sahelanthropus confirms habitual bipedalism, but not exclusively.

Scientists say a shipwreck off Patagonia is a long-lost 1850s Rhode Island whaler      (via sciencedaily.com) 

Scientists investigating the remains of an old wooden ship off the cold, windy coast of far southern Argentina say it almost certainly is the Dolphin, a globe-trotting whaling ship from Warren, R.I., lost in 1859. Archaeologists have spent years researching the ship's origin without making a definitive identification, but a new analysis of tree rings in its timbers has provided perhaps the most compelling evidence yet.

Analysis of everyday tools challenges long-held ideas about what drove major changes in ancient Greek society      (via sciencedaily.com) 

A modern scientific analysis of ancient stone tools is challenging long-held beliefs about what caused radical change on the island of Crete, where the first European state flourished during the Bronze Age: the 'Minoan civilization.'

Study of ancient skulls sheds light on human interbreeding with Neanderthals      (via sciencedaily.com) 

Research has established that there are traces of Neandertal DNA in the genome of modern humans. Now an exploratory study that assessed the facial structure of prehistoric skulls is offering new insights, and supports the hypothesis that much of this interbreeding took place in the Near East -- the region ranging from North Africa to Iraq.

Medieval monks were 'riddled with parasites'      (via sciencedaily.com) 

Research examining traces of parasites in medieval Cambridge residents suggests that monks were almost twice as likely as ordinary townspeople to have intestinal worms -- despite monasteries of the period typically having far more sanitary facilities.

Evidence that giant meteorite impacts created the continents      (via sciencedaily.com)     Original source 

New research has provided the strongest evidence yet that Earth's continents were formed by giant meteorite impacts that were particularly prevalent during the first billion years or so of our planet's four-and-a-half-billion year history.

No, the human brain did not shrink 3,000 years ago      (via sciencedaily.com) 

Did the 12th century B.C.E. -- a time when humans were forging great empires and developing new forms of written text -- coincide with an evolutionary reduction in brain size? Think again, says a team of researchers whose new paper refutes a hypothesis that's growing increasingly popular among the science community.

What's new under the sun? Offering an alternate view on how 'novel' structures evolve      (via sciencedaily.com) 

New research provide evidence that the crustacean carapace, along with other plate-like structures in arthropods (crustaceans, insects, arachnids, and myriapods) all evolved from a lateral leg lobe in a common ancestor more than 500 million years ago. This work further supports their proposal for a new concept of how novel structures evolve -- one which suggests that they aren't so novel, after all.
