One of the theories of evolution is that our genus, Homo, evolved from small-bodied early humans to become the taller, heavier and longer-legged Homo erectus that was able to migrate beyond Africa and colonize Eurasia. New research suggests our genus has come in different shapes and sizes since its origins over two million years ago, and adds weight to the idea that humans began to colonize Eurasia while still small and light.

New findings from an international team of archeological researchers highlight the complexity of geopolitics in Aztec era Mesoamerica and illustrate how the relationships among ancient states extended beyond warfare and diplomacy to issues concerning trade and the flow of goods.
Dame Mary Douglas (nee Margaret Mary Tew) was a British anthropologist born to colonial parents in Italy on March 25, 1921. Raised as a Roman Catholic, she was a supporter of structural analysis with an interest in comparative religion.
By studying the skeletal remains of seven horses and one camel found in an area called Wally’s Beach, located about 80 miles south of Calgary in Canada, researchers found that prehistoric Ice Age people hunted the animals 13,300 years ago in North America, much earlier than previously believed.
New observations made with telescopes reveal that the star that European astronomers saw appear in the sky in 1670 was not a nova, but a much rarer, violent breed of stellar collision. It was spectacular enough to be easily seen with the naked eye during its first outburst, but the traces it left were so faint that very careful analysis using submillimeter telescopes was needed before the mystery could be explained.
Jupiter may have swept through the early solar system like a wrecking ball, destroying a first generation of inner planets before retreating into its current orbit, according to a new study. The find helps explain why our solar system is so different from the hundreds of other planetary systems that astronomers have discovered in recent years.
A new international study casts doubt on the leading theory of what causes ice ages around the world— changes in the way the Earth orbits the sun. The researchers found that glacier movement in the Southern Hemisphere is influenced primarily by sea surface temperature and atmospheric carbon dioxide rather than changes in the Earth's orbit, which are thought to drive the advance and retreat of ice sheets in the Northern Hemisphere.
A new analysis of a medieval cesspit in the Christian quarter of the old city of Jerusalem has revealed the presence of a number of ancient parasite eggs, providing a window into the nature and spread of infectious diseases in the Middle East during the 15th century.
A newly discovered crocodilian ancestor may have filled one of North America's top predator roles before dinosaurs arrived on the continent. Carnufex carolinensis, or the "Carolina Butcher," was a 9-foot long, land-dwelling crocodylomorph that walked on its hind legs and likely preyed upon smaller inhabitants of North Carolina ecosystems, such as armored reptiles and early mammal relatives.
Scientists have resolved pieces of a nearly 200-year-old evolutionary puzzle surrounding the group of mammals that Charles Darwin called the “strangest animals ever discovered.”
Today's rich variety of beetles may be due to an historically low extinction rate rather than a high rate of new species emerging, according to a new study. These findings were revealed by combing through the fossil record.
Paleontologists have tapped a fossil from the most precisely dated beaked whale in the world - and the only stranded whale ever found so far inland on the African continent - to pinpoint, for the first time, a date when East Africa's mysterious elevation began.
Scientists recently detected the minor planet Chariklo’s ring system — a surprising finding, as it had been thought that centaurs are relatively dormant. Now scientists at MIT and elsewhere have detected a possible ring system around a second centaur, Chiron.
Researchers have discovered a dramatic decline in genetic diversity in male lineages 4,000 to 8,000 years ago- likely the result of the accumulation of material wealth- while in contrast, female genetic diversity was on the rise. This male-specific decline occurred during the mid- to late-Neolithic period.
A Venezuelan evolutionary biologist and a U.S. zoologist say they have refuted — through mitochondrial DNA sequencing — a recent claim also based on such sequencing that an unknown type of bear must exist in the Himalayas and that it may be, at least in part, the source of yeti legends.
Our skeletons hold tell-tale signs that show that human bipedalism– walking upright and on two feet– is unique to humans especially when compared to our closest living relatives, apes. Exactly when these signs first appear in our evolutionary history is one of the fundamental questions driving the study of human evolution.
An international research team has shed new light on the diet of some of the earliest recorded humans in Sri Lanka. The researchers analyzed the carbon and oxygen isotopes in the teeth of 26 individuals, with the oldest dating back 20,000 years. They found that nearly all the teeth analyzed suggested a diet largely sourced from the rainforest.
Archeologists say two pretzels unearthed during a dig on the banks of the Danube in the German city of Regensburg could be more than 300 years old— and are little different to the doughy product available in the state's famous beer halls today.
Laboratory Equipment’s scientist of the week is Nils Stenseth, from the Univ. of Oslo. He and a team discovered that a long believed theory is half correct. Climate fluctuation was, indeed, linked to Europe’s plague… but it was Asia’s climate.
Scientists from Greece and the UK have used slime molds to help look back to a period from the first century BC to the fourth century AD when Roman roads were being built in the Balkans. The work found that slime mold imitates the organic development of roads.
A newly developed genetic technique enabled researchers to sequence DNA from the teeth of 300-year-old skeletons, helping to pinpoint where in Africa three slaves had likely lived before being captured.
A study of nearly 2,000-year-old livestock teeth show that early herders from northern Africa could have traveled past Kenya’s Lake Victoria on their way to southern Africa because the area was grassy– not tsetse fly-infested bushland as previously believed.
Geneticists have discovered that millions of modern Asian men are descended from 11 powerful dynastic leaders who lived up to 4,000 years ago— including Mongolian warlord Genghis Khan. The study examined the male-specific Y chromosome, which is passed from father to son, in more than 5,000 Asian men belonging to 127 populations.
The ancient Mongols have a reputation for having been fierce warriors. A new study shows them to have been unmatched polluters. Ancient copper and silver production created four times more pollution than today’s methods.
The study of diseases such as bubonic plague, smallpox or scurvy is about more than simply gleaning historical information from a cabinet of increasingly distant medical curiosities. As time goes by, scientific knowledge is not just informing the work of historians; it is being informed by it. The work is providing vital new information in the fight against modern-day “plagues,” such as cancer and dementia.
A team of anthropology researchers has found significant differences in facial features between seven different pre-Columbian peoples they evaluated from what is now Peru– disproving a longstanding perception that these groups were physically homogenous. The finding may lead scholars to revisit any hypotheses about human migration patterns that rested on the idea that there was little skeletal variation in pre-Columbian South America.
