more closely than any other known living organisms, but at the time it was a daring act to classify human beings within the same framework used for the rest of nature.
Use of this concept, together with a reanalysis of the fossil record, moved the estimated time of the evolutionary split between apes and human ancestors forward to as recently as about 5 mya.
Since then the molecular data and a steady trickle of new hominin fossil finds have pushed the earliest putative hominin ancestry back in time somewhat, to perhaps 8–6 mya., based on a cranium from of Chad in north-central Africa.
Radiocarbon tests of carbonized plant remains where artifacts were unearthed last May along the Savannah River in Allendale County by University of South Carolina archaeologist Dr.
Albert Goodyear indicate that the sediments containing these artifacts are at least 50,000 years old, meaning that humans inhabited North American long before the last ice age.
Using his home-made “laufmaschine” (running machine), later dubbed a “dandyhorse” or “draisine” after its inventor, the baron managed a 14km trip in less than hour.
Faster than the post coach, this was a one-man mobility revolution. A horse that eats nothing and isn’t a horse,” exclaims an alarmed housemaid onstage Mannheim’s Capitol Theater in a new musical reimagining that maiden trip in 1817.
Evidence of modern man's migration out of the African continent has been documented in Australia and Central Asia at 50,000 years and in Europe at 40,000 years.
The fact that humans could have been in North America at or near the same time is expected to spark debate among archaeologists worldwide, raising new questions on the origin and migration of the human species.
The does not indicate with certainty if this species was at all terrestrial, although the fairly forward position of its foramen magnum (the hole through which the spinal cord exits the braincase) may suggest a habitually upright posture.
