How old is human race? New data

Share

New archeological evidences have been found in Ethiopia. As it turned out, the human race may be 80,000 years older than scientists previously believed.

It took archaeologists more than 35 years to determine the age of tools discovered in the Ethiopian Rift Valley. With the help of modern techniques they revealed that those tools could be at least 276,000 years old. Until that moment the oldest samples of Homo sapien bones were found to have 195,000 years.

The discovery was made due to argon-argon dating. This reliable method is used to compare isotopes of argon in order to define more precisely the age of geological materials.

Paul Renne, director of Berkeley Geochronology Center, said that making of small blades found in Gademotta required manual dexterity, as well as integrated cognitive capabilities. As scientists suppose, these tools can be referred to the beginning of Homo sapiens development.

"It seems that we were technologically more advanced at an earlier time that we had previously thought," said Leah Morgan, study co-author.

According to the information provided by National Geographic, Gademotta, the place of discovery, offered favorable living conditions for settlers as it had access to fresh water from the Lake Ziway and supplied them with black rock glass called obsidian.

"Due to its lack of crystalline structure, obsidian glass is one of the best raw materials to use for making tools," said Morgan.

It's interesting to note that researchers came across a gap about 300,000 years ago over the period of Stone Age. Large-seized unpolished stone-axes representing Acheulean period gave way to finer blades of the Middle Stone Age which varied in form. Referring to the Afar region in Ethiopia, it should be mentioned that the change of technology happened about 160,000 years ago.

"A modern analogy might be the transition from ox-carts to automobiles, which is virtually complete in North America and northern Europe, but is still underway in the developing world," expressed his opinion Renne.

According to Leah Morgan from the University of California, the technological progress started earlier in Gademotta due to available sources of obsidian. However, it's still difficult to say, who created those tools. Some experts suppose it could be Homo sapiens. Their opponents claim that a different human species could have the necessary intellectual abilities and manual nimbleness. Nevertheless, these findings are of paramount importance for science.

"The new date for Gademotta changes how we think about human evolution, because it shows how much more complicated the situation is than we previously thought," said Laura Basell, an archaeologist from the University of Oxford.

The study carried out in Gademotta was funded by the National Geographic Society's Committee for Research and Exploration. Results of the investigation will be presented in the journal Geology.

It is possible that the human race is more than 200,000 years old or even 1,000,000 perhaps. The reason mainstream scientists have a hard time accepting this is because they look at human technological advancement as "linear" instead of "cyclical".
If you believe human achievement is linear, you havn't learned what is evedent from human history that we can study. The recent human history we are able to study shows us that as civilizations rise and fall, technology is lost i.e. the ancient Egyptian, Greek and Roman civilization's were far more advanced than any civilization durring the "Dark ages".
I believe that human advancement is cyclical and we are not the most advancd civilization ever to develop on the Earth.
You might say, "where is the evidence of previous civilizations?". Well, Google prehistoric civilizations in Turkey, Africa and Bosnia. There is evidence of much older civilizations than previously thought and they predate the last ice age.
The other arguement against my theory is that there is no evidence of technology such as TV, Computers automobiles etc. To that I say that it is common knowledge we have been coming out of an ice age for the last 10,000 years. What if our civilization was covered in ice 3 or 4 MILES thick and as the ice moved, it ground everything to a fine powder and back to it's base elements?
Would there be much evidence that we existed? Once civilization falls, it becomes an every survivor for himself scenario and previous technological advancements become unimportant due to the immediate food and shelter required to survive that day.
The ones that survive a global disaster such as an ice age rarely understand the technology they previously used everyday. Most people cant fix their car let alone rebuild a powergrid. Not to mention the ice age would last a very long time so the previous technology would be lost forever. To say the earth is 6000 years old is pure stupidity and the bible never makes that claim! The "church" made that rediculous claim before anyone knew about dinosaurs and has been trying to make it true ever since, just like when they made it heracy to even suggest that the earth was round and not flat.

the tools found which is 276.000 years old made outoff stones may be older than homo sapiens age.so it does not mean that mans age is 276.000.
