Archaeologists on Monday announced the discovery of a fossilized human finger bone in the desert of Saudi Arabia that they said was 85, years old. If confirmed, the finding would be the first and earliest Homo sapiens fossil found on the Arabian Peninsula, as well as the oldest specimen of our species to be directly dated outside of Africa and its doorstep, the Levant. Along with recent finds of 80,year-old human teeth from Asia and 65,year-old human relics from Australiathe Arabian finger bone provides further evidence that early modern humans spread out of Africa much earlier and farther than previously thought.

The mysterious human ancestor called Homo naledi was primed for success in a prehistoric triathlon, new research shows—if the challenges were walking upright, climbing trees, and handily wielding tools.
The earliest of our ancestors to show a significant increase in brain size and also the first to be found associated with stone tools. This is the same genus or group name as the one give to modern humans and is used to show the close relationship between this species and our own. The discovery of Homo habilis began in when two teeth were unearthed at Olduvai Gorge in Tanzania by a team led by Louis and Mary Leakey.
Humans have a distinctive hand anatomy that allows them to make and use tools. Apes and other nonhuman primates do not have these distinctive anatomical features in their hands, and the point in time at which these features first appeared in human evolution is unknown. Now, a University of Missouri researcher and her international team of colleagues have found a new hand bone from a human ancestor who roamed the earth in East Africa approximately 1.
Pending consensus on its taxonomic status, it has been referred to as Homo denisovaHomo altaiensisor Homo sapiens denisova. Inscientists announced the discovery in an Altai permafrost cave of a finger bone  of a juvenile female found in the Denisova Cave in the Altai Mountains in Siberiaa cave that has also been inhabited by Neanderthals and modern humans. The nuclear genome from this specimen suggested that Denisovans shared a common origin with Neanderthals, that they ranged from Siberia to Southeast Asiaand that they lived among and interbred with the ancestors of some modern humans,  with about three to five percent of the DNA of Melanesians and Aboriginal Australians and around six percent in Papuans deriving from Denisovans.
A tiny bone of an early human species, possibly Homo erectusfound in Kenya is the earliest evidence of a modern human-like hand, according to a team of scientists led by Prof Carol Ward from the University of Missouri.

Pre- Homo human ancestral species, such as Australopithecus africanusused human-like hand postures much earlier than was previously thought. Some of the morphological characteristics of the human hand are different from that of other primates enabling us to grab objects with precision and use them exerting a force. Yet, how did our early human ancestors use their hands?

PARIS, France — A lone finger bone unearthed in the desert suggests modern humans had penetrated deep into Arabia already 85, years ago, said a study published on Monday that claimed to advance our African exodus by millennia. Recent archaeological finds have started to question that idea, with some claiming evidence of homo sapiens spreading beyond Africa and the adjacent Levant region alreadyyears ago or more. A directly dated Homo sapiens phalanx from the Nefud desert reveals human presence in the Arabian Peninsula before 85, years ago.
Today, we ask a chicken-and-egg question. The University of Houston's College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them. D oes the human mind drive our technology, or does our technology drive the human mind? When we talk about our technology we normally sound as though we believe ourselves to be in control.
