How old are the Omo 1 fossils?
Turns out our species is older than we previously thought. Fossils excavated from the Omo Kibish formation in southwestern Ethiopia are some of the oldest known human human fossils. The Omo I remains, bones thought to be less than 200,000 years old, have now been found to date back to some 230,000 years ago.

During Richard Leakey's original 1967 excavations several stone tools were found in association with Omo 1 at Kamoya's hominid site (KHS) but were not well described in the research literature.
What does Omo 1 suggest about human evolution?
Omo I has features that suggest this skeleton belonged to a female. The stature estimates in this study were derived from multiple bones from the upper and lower part of the body, and suggest that there may be differences in the upper and lower limb proportions of the earliest modern humans compared to recent humans.
When was the first human born?

What is the oldest known human?
Scientists determine age of some of the oldest human bones Some of the oldest human remains ever unearthed are the Omo One bones found in Ethiopia. For decades, their precise age has been debated, but a new study argues they're around 233,000 years old.
How old are the Omo remains?
approximately 233,000 years oldIn 2022, a study by Vidal et al. found an earlier age for the Omo fossils than previously reported, revising the date assigned to them as, a minimum date of approximately 233,000 years old.
How old is oldest human remains?
The remains, known as Omo I, were found in southwest Ethiopia in the late 1960s. The bone and skull fragments researchers discovered were some of the oldest known remains of Homo sapiens. Initial research suggested they were nearly 200,000 years old, but new research shows the remains are at least 230,000 years old.
Did all humans come from Africa?
Our species likely arose in many places around Africa, not just around the Kalahari Desert, critics say. A new genetic study suggests all modern humans trace our ancestry to a single spot in southern Africa 200,000 years ago.
What did the first humans look like?
With the exception of Neanderthals, they had smaller skulls than we did. And those skulls were often more of an oblong than a sphere like ours is, with broad noses and large nostrils. Most ancient humans had jaws that were considerably more robust than ours, too, likely a reflection of their hardy diets.
Where did the first humans come from?
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.
How old are the Omo remains?

What is the oldest fossil ever found?
cyanobacteriaThe oldest known fossils, in fact, are cyanobacteria from Archaean rocks of western Australia, dated 3.5 billion years old. This may be somewhat surprising, since the oldest rocks are only a little older: 3.8 billion years old! Cyanobacteria are among the easiest microfossils to recognize.

How old is the oldest Homosapien?
The age of the oldest Homo sapien discovered, Omo One, is at least 230,000 years old. When it was first found under volcanic ash in Ethiopia in the 1960s, it was believed to be nearly 200,000 years old. A team from the University of Cambridge has cleared up the age by dating the volcanic rocks above it.
What does OMO mean?
Open market operations or OMO is a practice whereby the Federal Reserve in the U.S. purchases or sells securities such as Treasury notes from the member banks. It does this to ensure regulation of the money supply that is stored as a reserve in the various U.S. banks.

That is, depending on the federal fund rate, the banks will either increase or decrease their interest rate. This directly affects the consumers and businesses as their willingness to borrow from the bank depends on the interest rate.

What is the difference between omo I and omo II?
The Omo I fossils indicate more modern traits, while studies of the postcranial remains of Omo II indicate an overall modern human morphology with some primitive features. The fossils were found in a layer of tuff, between a lower, older geologic layer named Member I and a higher, newer layer dubbed Member III.
What are the bones of Omo?
The bones include two partial skulls, four jaws, a legbone, around two hundred teeth and several other parts. The specimens, Omo I and Omo II, are both classified as anatomically modern humans ( Homo sapiens) but differ from each other in morphological traits. The Omo I fossils indicate more modern traits, while Studies of the postcranial remains of Omo II indicate an overall modern human morphology with some primitive features. The fossils were found in a layer of tuff, between a lower, older geologic layer named Member I and a higher, newer layer dubbed Member III. The Omo I and Omo II hominin fossils were taken from similar stratigraphic levels over Member I.

How long ago was the Member I layer?
About 30 years after the original finds, a detailed stratigraphic analysis of the area surrounding the fossils was done. The Member I layer was argon-dated to 195,000 years ago, and the (higher layer) Member III was dated to 105,000 years ago. Numerous recent lithic records verify the tool technology from Members I and III to the Middle Stone Age.
