It seems that “Lucy” was not the only hominin on the block in northern Africa about 3 million years ago. A team of researchers that included Johns Hopkins University geologist Naomi Levin has announced the discovery of a partial foot skeleton with characteristics (such as an opposable big toe bone) that don´t match those of Lucy, the human ancestor (or hominin) known to inhabit that region and considered by many to be the ancestor of all modern humans. The discovery is...

Experiment stresses consequences of placing newly discovered fossils on human family tree Someday a future intelligent organism could sweep away a million years of dust and find the bones of a Homo sapiens and wonder what he was. Further research would show Homo sapiens walked upright, lived in communities and buried their dead. But this future intelligent organism might be faced with an old puzzle--determining where Homo sapiens came from. "If their cognitive world induced them to ask the...

"Too simple" and "not so fast" suggest biological anthropologists from the George Washington University and New York University about the origins of human ancestry. In the upcoming issue of the journal Nature, the anthropologists question the claims that several prominent fossil discoveries made in the last decade are our human ancestors. Instead, the authors offer a more nuanced explanation of the fossils' place in the Tree of Life. They conclude that instead of being our ancestors the...

A 6 million-year-old early relative of modern humans apparently walked on two feet, pushing back the origins of so-called bipedalism, according to a new study of a fossil found in Kenya. "I would say at this point it's the earliest fossil hominin that we can clearly identify as bipedal," said paleoanthropologist William Jungers of Stony Brook University, who conducted a quantitative analysis with Brian Richmond of George Washington University of a fossilized femur bone from the...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
