Evidence Suggests Humans Reached “Roof of the World” 40,000 Years Ago

Over 3,000 stone tools show human presence in Tibetan plateau 20,000 years before previously thought

Several of the newly identified stone tools – unearthed from a museum collection.

A Fresh Look at These Stone Tools Reveals a New Chapter of Ancient Chinese History

Archaeologists thought these ancient tools, 80,000 years old at least, were brought to China by migrants—but now it appears they were invented locally

The Science and Cell teams sequenced a total of 64 ancient human genomes

This Week Has Offered a Slew of Insights on the Western Hemisphere’s First Humans

Studies reveal rapid yet uneven movement south in at least three migratory waves, complicating story of the Americas’ settlement

This painting of a cattle-like animal in a Borneo cave has been dated at at least 40,000 years old, making it the oldest known figurative rock art in the world.

World’s Oldest Known Figurative Paintings Discovered in Borneo Cave

Dated to at least 40,000 years old, the depiction of a cattle-like animal has striking similarities to ancient rock art found in other parts of the world

Abnormalities identified included misshapen skulls and jaws, bowed femur and arm bones

Did Rampant Inbreeding Contribute to Early Humans’ High Rate of Skeletal Deformities?

Researcher identified 75 skeletal or dental defects in sample of just 66 sets of ancient remains

Ancient Teeth With Neanderthal Features Reveal New Chapters of Human Evolution

The 450,000-year-old teeth, discovered on the Italian Peninsula, are helping anthropologists piece together the hominid family tree

Scientists analyzed 3D scans of entheses, or scars left at points where muscle attaches to bone

Neanderthals Used Their Hands for Precision, Not Just Power

Researchers suggest that the early human ancestors’ hand usage places them in line with tailors, painters rather than brute-force laborers

Humans' CMAH gene mutation may enable them to exhibit higher endurance over long periods of exercise

Human Gene Mutation May Have Paved the Way for Long-Distance Running

Mice with engineered versions of the CMAH gene exhibited 30 percent better endurance than those without

New Research

Chimps and Toddlers Use Same Gestures to Get Attention

A new study shows 12 to 24 month old children and chimps use 46 of the same movements to communicate, including stomping, pointing and clapping

Cool Finds

Meet Denisova 11: First Known Hybrid Hominin

The 13-year-old girl’s mother was a Neanderthal while her father was a Denisovan

Study suggests that early humans had opposable, ape-like big toes built for grasping

Researchers Suggest Big Toe Was Last Part of Foot to Evolve

Early hominins’ big toes were equipped for life on the ground and in the trees

Early humans made stone tools out of whichever rocks happened to be lying nearby, ignoring quality in favor of convenience

Laziness May Have Contributed to the Decline of Homo Erectus

Researchers suggest early humans pursued “least-effort strategies” when crafting tools, collecting resources

Liang Bua cave on Flores Island, where Homo floresiensis remains were discovered in 2003. Nearby is a village where the pygmies live.

New Research

A New Genetic Study Suggests Modern Flores Island Pygmies and Ancient Hobbits Are Unrelated

The island dwarfism effect seems to have occurred independently in each population, thousands of years apart

Humans and other animals share large amounts of genetic material, making geneticists rethink the traditional notion of inheritance.

New Research

Genes That Jump Between Species Could Rewrite Our Understanding of Evolution

Horizontal movement of genetic material is widespread across animals, challenging traditional notions of inheritance

Behaviors requiring the most pressure were smashing bones for marrow and producing flint flakes

Did the Human Hand Evolve as a Lean Mean Bone-Smashing Machine?

Of nearly 40 things Pleistocene people might have done with their hands, getting to yummy marrow requires the most force and dexterity
