The purpose of such an elaborate structure remains a big open question

Several Homo erectus skulls were recently identified as the youngest known fossils of the species, some 108,000 to 117,000 years old. These fossil replicas are housed at the University of Iowa.

Fossils From Some of the Last Homo Erectus Hint at the End of the Long-Lived Species

<em>Homo erectus</em>, one of the first species of the Homo genus, survived for longer than any other close human ancestor

A 5,700-year-old piece of birch tar, chewed as gum, contains the genome, mouth microbes, and even dietary information about its former chewer.

Human Genome Recovered From 5,700-Year-Old Chewing Gum

The piece of Birch tar, found in Denmark, also contained the mouth microbes of its ancient chewer, as well as remnants of food to reveal what she ate

Human Ancestors May Have Evolved the Physical Ability to Speak More Than 25 Million Years Ago

Though when primates developed the cognitive abilities for language remains a mystery

Artist‘s reconstruction of Mesophthirus engeli of elder development stage feeding on the dinosaur feathers from mid-Cretaceous amber.

Lice-Filled Dinosaur Feathers Found Trapped in 100-Million-Year-Old Amber

Prehistoric insects that resemble modern lice infested animals as early as the mid-Cretaceous, living and evolving along with dinosaurs and early birds

Modern-day baby feeding from reconstructed infant feeding vessel of the type investigated in the new study.

Bronze Age Baby Bottles Reveal How Some Ancient Infants Were Fed

Drinking vessels found in Bronze and Iron Age children's graves contained proteins from animal milk

This image shows a preliminary portrait of a juvenile female Denisovan based on a skeletal profile reconstructed from ancient DNA.

Scientists Recreate the Face of a Denisovan Using DNA

By mapping gene expressions, researchers can determine some anatomical features of our distant hominin relatives

A photograph of a red slipped ware globular pot placed near the head of the skeleton that yielded ancient DNA. There are lines as well as indentations on the upper right side, just below the rim. The indentations on the body of the pot could be examples of ancient graffiti and/or "Indus script."

Rare Ancient DNA Provides Window Into a 5,000-Year-Old South Asian Civilization

The Indus Valley Civilization flourished alongside Mesopotamia and Egypt, but the early society remains shrouded in mystery

The remarkably complete skull of a human ancestor of the genus Australopithecus fills in some of the gaps in the human evolutionary tree.

A 3.8-Million-Year-Old Skull Puts a New Face on a Little-Known Human Ancestor

The cranium of a male <i>Australopithecus anamensis</i>, a close relative of Lucy, provides clues about one of the earliest hominins to walk on two legs

Mount Bromo erupting in Indonesia. Prior to 20th century industrialization, volcanoes were a primary driver of regional temperature changes over timescales of two or three decades, one of the studies found.

Modern Climate Change Is the Only Worldwide Warming Event of the Past 2,000 Years

New research finds that previous periods of warming and cooling driven by natural causes were regional shifts in temperature rather than global events

An ancient population of Arctic hunter-gatherers, known as Paleo-Eskimos, made a significant genetic contribution to populations living in Arctic North America today.

Ancient DNA Reveals Complex Story of Human Migration Between Siberia and North America

Two studies greatly increase the amount of information we have about the peoples who first populated North America—from the Arctic to the Southwest U.S.

A collection of Hominin teeth used to determine the rate of tooth evolution among human ancestors.

The Teeth of Early Neanderthals May Indicate the Species' Lineage Is Older Than Thought

Some of the oldest known Neanderthal remains include teeth that could push back the split with modern human lineages, but not all scientists are convinced

Twelve Epic Migratory Journeys Animals Take Every Spring

As temperatures rise and foliage blooms in the north, creatures from insects to whales set out for long treks across the planet

As humans began eating softer foods, overbites may have become more common and pronounced.

The Ability to Pronounce 'F' and 'V' Sounds Might Have Evolved Along With Diet

As our ancestors began eating softer agricultural foods, the shape of the human jaw and the sounds we make may have changed as well

The stone circle Ring of Brodgar on the Orkney Islands, Scotland.

Europe’s Megalithic Monuments Originated in France and Spread by Sea Routes, New Study Suggests

The ancient burial structures, strikingly similar all across Europe and the mediterranean, have puzzled scientists and historians for centuries

Artificial Intelligence Study of Human Genome Finds Unknown Human Ancestor

The genetic footprint of a "ghost population" may match that of a Neanderthal and Denisovan hybrid fossil found in Siberia

Hand axes from the site of Saffaqah, Saudi Arabia.

Stone Tools at Arabian “Crossroads” Present Mysteries of Ancient Human Migration

Hominins made stone tools in central Arabia 190,000 years ago, and the hand axe technology raises questions about just who they were

Coral Larvae Cryogenically Frozen and Thawed for the First Time

Warming oceans are killing the world’s reefs, but scientists may have found a way to help them get out of hot water—by putting corals into a deep freeze

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
