This new discovery just brings to realization of how far we have come in understanding man's history, BUT continues to create so many more questions
of just how we lived, migrated, interacted over 100,000's of thousdands of years.
Just a fascinating read for those interested, and how we continue to find new evidence of man, our interaction with Neanderthals and our traverse
across the continents.
Hints at new hidden complexities in the human story came from a 400,000-year-old femur found in a cave in Spain called Sima de los Huesos (“the
pit of bones” in Spanish). The scientific team used new methods to extract the ancient DNA from the fossil.
“This would not have been possible even a year ago,” said Juan Luis Arsuaga, a paleoanthropologist at Universidad Complutense de Madrid and a
co-author of the paper.
Scientists have found the oldest DNA evidence yet of humans’ biological history. But instead of neatly clarifying human evolution, the finding
is adding new mysteries.
The fossil, a thigh bone found in Spain, had previously seemed to many experts to belong to a forerunner of Neanderthals. But its DNA tells a very
different story. It most closely resembles DNA from an enigmatic lineage of humans known as Denisovans. Until now, Denisovans were known only from DNA
retrieved from 80,000-year-old remains in Siberia, 4,000 miles east of where the new DNA was found.
The mismatch between the anatomical and genetic evidence surprised the scientists, who are now rethinking human evolution over the past few
hundred thousand years. It is possible, for example, that there are many extinct human populations that scientists have yet to discover. They might
have interbred, swapping DNA. Scientists hope that further studies of extremely ancient human DNA will clarify the mystery.
One of the mysteries that has scientists interested and shaking their heads is the close DNA mapping of the Denisovans located in Siberia indicating
that they had lived there about 41,000 years ago, but only in that area of Siberia,
found in the remote Denisova Cave in the Altai Mountains in
Siberia, a cave which has also been inhabited by Neanderthals and modern humans.
One of the fascinating observations was

It was just back in 1996 that Scientists excavating in the dusty Middle Awash region of Ethiopia have unearthed an amazingly complete skeleton of a
new species of hominid -- an ancestor to modern man -- which they have named Ardipithecus ramidus, nicknamed "Ardi".

Daily Tech Story of 'Ardi'
The find began in 1994 with the unearthing of a hominid hand. One and a half decades later, Ardi was revealed in her full form, a skeleton
consisting of over 125 bone pieces. Among the most complete hominid skeletons found to date, Ardi is approximately 4.4 million years old, 1.2 million
years older than the famous "Lucy" (Australopithecus afarensis) skeleton. Ardi is in fact the oldest hominid found to
Just an exciting time in human history and trying to put the puzzle of man, it's beginning and how we got to where we are today together.......I have
a feeling there is still a lot we just don't know and many more surprising finds that will shake current day paradigms. Enjoy!!
