Lost medieval chapel sheds light on royal burials at Westminster Abbey, finds new study featuring 15th-century reconstruction      (via sciencedaily.com) 

New evidence, helping to form a 15th-century reconstruction of part of Westminster Abbey, demonstrates how a section of the building was once the focus for the royal family's devotion to the cult of a disemboweled saint and likely contained gruesome images of his martyrdom.

Mammoth problem with extinction timeline      (via sciencedaily.com)     Original source 

Paleontologists say environmental DNA is not always helpful in identifying when animals like mammoths went extinct because genetic material found in sediment could have come from animals that died thousands of years earlier.

DNA sequence enhances understanding origins of jaws      (via sciencedaily.com) 

Researchers have discovered and characterized a DNA sequence found in jawed vertebrates, such as sharks and humans, but absent in jawless vertebrates, such as lampreys. This DNA is important for the shaping of the joint surfaces during embryo development.

Ancient superpredator got big by front-loading its growth in its youth      (via sciencedaily.com)     Original source 

Whatcheeria, a six-foot-long salamander-like creature that lived 340 million years ago, was the T. rex of its time: the biggest, baddest predator in its habitat. A new study reveals how they grew to their 'giant' size: instead of growing slow and steady throughout their lives like many modern reptiles and amphibians, they did most of their growing when they were young.

525-million-year-old fossil defies textbook explanation for brain evolution      (via sciencedaily.com) 

According to a new study, fossils of a tiny sea creature with a delicately preserved nervous system solve a century-old debate over how the brain evolved in arthropods, the most species-rich group in the animal kingdom. Combining detailed anatomical studies of the fossilized nervous system with analyses of gene expression patterns in living descendants, they conclude that a shared blueprint of brain organization has been maintained from the Cambrian until today.

A team of researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.

1,700-year-old spider monkey remains discovered in Teotihuacán, Mexico      (via sciencedaily.com)     Original source 

The complete skeletal remains of a spider monkey -- seen as an exotic curiosity in pre-Hispanic Mexico -- grants researchers new evidence regarding social-political ties between two ancient powerhouses: Teotihuacán and Maya Indigenous rulers. The remains of other animals were also discovered, as well as thousands of Maya-style mural fragments and over 14,000 ceramic sherds from a grand feast. These pieces are more than 1,700 years old.

Welsh 'weird wonder' fossils add piece to puzzle of arthropod evolution      (via sciencedaily.com)     Original source 

International team of researchers describe new fossil species discovered in fossil deposit near Llandrindod Wells in mid-Wales. The fossil, Mierridduryn bonniae, shares many features with Cambrian 'weird wonder' Opabinia, but is 40 million years younger. Robust phylogenetic analyses suggest that Mierridduryn is either the third opabiniid ever discovered, or is a distinct group that is key for understanding the evolution of the arthropod head.

Earth's oldest stromatolites and the search for life on Mars      (via sciencedaily.com) 

The earliest morphological traces of life on Earth are often highly controversial, both because non-biological processes can produce relatively similar structures and because such fossils have often been subjected to advanced alteration and metamorphism. Stromatolites, layered organo-sedimentary structures reflecting complex interplays between microbial communities and their environment, have long been considered key macrofossils for life detection in ancient sedimentary rocks; however, the biological origin of ancient stromatolites has frequently been criticized.

Ancient DNA analysis sheds light on the early peopling of South America      (via sciencedaily.com) 

Using DNA from two ancient humans unearthed in two different archaeological sites in northeast Brazil, researchers have unraveled the deep demographic history of South America at the regional level with some surprising results. Not only do they provide new genetic evidence supporting existing archaeological data of the north-to-south migration toward South America, they also have discovered migrations in the opposite direction along the Atlantic coast -- for the first time. Among the key findings, they also have discovered evidence of Neanderthal ancestry within the genomes of ancient individuals from South America.
