Jawbone may represent earliest presence of humans in Europe      (via sciencedaily.com) 

For over a century, one of the earliest human fossils ever discovered in Spain has been long considered a Neanderthal. However, new analysis from an international research team dismantles this century-long interpretation, demonstrating that this fossil is not a Neanderthal; rather, it may actually represent the earliest presence of Homo sapiens ever documented in Europe.

Ancient DNA from medieval Germany tells the origin story of Ashkenazi Jews      (via sciencedaily.com) 

Extracting ancient DNA from teeth, an international group of scientists peered into the lives of a once-thriving medieval Ashkenazi Jewish community in Erfurt, Germany. The findings show that the Erfurt Jewish community was more genetically diverse than modern day Ashkenazi Jews.

Fossil overturns more than a century of knowledge about the origin of modern birds      (via sciencedaily.com) 

Fossilized fragments of a skeleton, hidden within a rock the size of a grapefruit, have helped upend one of the longest-standing assumptions about the origins of modern birds.

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.

Human evolution wasn't just the sheet music, but how it was played      (via sciencedaily.com) 

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.

More than one way to build a black bird      (via sciencedaily.com) 

For a species of flycatcher in the remote Solomon Islands, scientists have so far found at least two genetic pathways leading to the same physical outcome: all-black feathers. This change was no random accident. It was a result of nature specifically selecting for this trait.

Fossil bird's skull reconstruction reveals a brain made for smelling and eyes made for daylight      (via sciencedaily.com) 

Piecing together the crushed skull of a fossil bird that lived alongside the dinosaurs helped researchers extrapolate what its brain would have looked like: big olfactory bulbs would have meant that this bird, the earliest known animal to eat fruit, had a better sense of smell than most modern birds. And the bones around its eye sockets revealed that it would have been better at seeing by day than at night.

Could South American volcanoes have triggered whale extinctions?      (via sciencedaily.com) 

Today, increasing levels of carbon dioxide in the atmosphere are warming up the planet. Climate change can disrupt the balance of ecosystems and contribute to endangerment and extinction of some species. New research suggests that a period of intense volcanism in the Central Andes may be the missing link in the story of past climate changes that led to the extinctions of ancient marine mammals.

Reign of Papua New Guinea Highland's megafauna lasted long after humans arrived      (via sciencedaily.com) 

A giant kangaroo that once roamed on four legs through remote forests in the Papua New Guinea Highlands may have survived as recently as 20,000 years ago -- long after large-bodied megafauna on mainland Australia went extinct, new research indicates. Palaeontologists, archaeologists and geoscientists, have used new techniques to re-examine megafauna bones from the rich Nombe Rock Shelter fossil site in Chimbu Province in a bid to better understand the intriguing natural history of PNG.

Revealing the genome of the common ancestor of all mammals      (via sciencedaily.com) 

An international team has reconstructed the genome organization of the earliest common ancestor of all mammals. The reconstructed ancestral genome could help in understanding the evolution of mammals and in conservation of modern animals. The earliest mammal ancestor likely looked like the fossil animal 'Morganucodon' which lived about 200 million years ago.

These female hummingbirds evolved to look like males -- apparently to evade aggression      (via sciencedaily.com) 

1 in 5 adult female white-necked jacobin hummingbirds look like males. New research shows that this is a rare case of 'deceptive mimicry' within a species: Females with male-like plumage are trying to pass themselves off as males, and as a result receive a benefit in the form of reduced aggression from males.
