ORIGIN OF LIFE ON EARTH
How Life Was Started on Planet Earth
Articles > UCLA scientists strengthen case for life more than 3.8 billion years ago
Ten years ago, an international team of scientists reported evidence, in a controversial cover story in the journal Nature, that life on Earth began more than 3.8 billion years ago–400 million years earlier than previously thought. A UCLA professor who was not part of that team and two of the original authors will report in late July that the evidence is stronger than ever.
The scientists see light carbon inclusions in a phosphate mineral called apatite, which is also the material of which bones and teeth are made.
"This paper shows, with far greater confidence than we ever had before, that these rocks are older than 3.8 billion years," said Manning, who has conducted extensive research in Greenland. "We have shown that the rocks are appropriate for hosting life.
Manning agrees, saying he is confident the rocks contain evidence of ancient life, but "it’s not a slam dunk."
An unanswered question is how life originally could have arisen from lifeless molecules and evolved into the already sophisticated isotope fractioning life forms recorded in the Akilia rocks.
The research on the Akilia rocks is federally funded by the National Science Foundation (http://www.nsf.gov/) and the NASA Astrobiology Institute (http://nai.arc.nasa.gov/), a partnership between NASA, 12 major U.S. teams and six international consortia.
The carbon aggregates in the rocks have a ratio of about 100-to-one of 12C (the most common isotope form of carbon, containing six protons and six neutrons) to 13C (a rarer isotopic form of carbon, containing six protons and seven neutrons). The light carbon, 12C, is more than 3 per cent more abundant than scientists would expect to find if life were not present, and 3 percent is very significant, Harrison said.
Carbon inclusions in the rocks were analyzed with UCLA’s high-resolution ion microprobe–an instrument.
For the first half of its history the Earth had an atmosphere of methane and carbon dioxide we would find impossible to breathe. One clue as to how the earth acquired its oxygen can be found in Australia. Shark Bay in Western Australia is home to strange bacterial mounds called stromatolites. The bacteria in these objects are pumping out oxygen. A few hundred miles away geologist Martin Van Kranendonk shows us a fossil stromatolite, the world’s oldest fossil. The evidence suggests that these strange objects are responsible for creating the air we breathe.Avenir Light is a clean and stylish font favored by designers.

Four and a half billion years ago, the young Earth was a hellish place—a seething chaos of meteorite impacts, volcanoes belching noxious gases, and lightning flashing through a thin, torrid atmosphere. Then, in a process that has puzzled scientists for decades, life emerged. But how? Mineralogist Robert Hazen as he journeys around the globe. From an ancient Moroccan market to the Australian Outback, he advances a startling and counterintuitive idea—that the rocks beneath our feet were not only essential to jump-starting life, but that microbial life helped give birth to hundreds of minerals we know and depend on today. It's a theory of the co-evolution of Earth and life that is reshaping the grand-narrative of our planet’s story.
The video shows that the results of research regarding the Origin of Life on earth. It shows how Life was started from Water, Minerals, Rocks, Clay & Mud more than billions of years ago. Which paved the way to present-day Life (Life and Rocks are part of the same story).
Life Created from Clay - Sounding Clay by God
The last Book revealed to Prophet Muhammed (pbuh), around 1400 years ago, mention in many verses the human's life creation from :
Clay commingled with water!
Create a human being out of clay.
Created man out of sounding clay, like pottery.
Holy Quran: As-Saffat (The Rangers) 37:11
فَاسْتَفْتِهِمْ أَهُمْ أَشَدُّ خَلْقًا أَم مَّنْ خَلَقْنَا إِنَّا خَلَقْنَاهُم مِّن طِينٍ لَّازِبٍ
AND NOW ask those [who deny the truth] to enlighten thee: Were they more difficult to create than all those [untold marvels] that We have created? - for, behold, them have We created out of [mere] clay commingled with water!
Holy Quran: Ar-Rahman (The Most Beneficent) 55:14
خَلَقَ الْإِنسَانَ مِن صَلْصَالٍ كَالْفَخَّارِ
He has created man out of sounding clay, like pottery,
