UM-Bot Posted September 8, 2014 #1 Share Posted September 8, 2014 (IP: Staff) · Scientists have determined that oxygen-producing life forms appeared around 3 billion years ago. Based on the work of researchers at Trinity College Dublin and Presidency University in Kolkata, the discovery suggests that oxygen-producing organisms responsible for making it possible for more complex life forms to evolve first appeared on Earth 60 million years earlier than previously believed.

Atuke Posted September 8, 2014 #2 Share Posted September 8, 2014 You have to wonder how the earliest organisms life force came about. And at what point it's considered alive and not alive. Because once alive, the earth exploded with life. Age old question, but what was the turning point? Link to comment Share on other sites More sharing options...
taniwha Posted September 8, 2014 #3 Share Posted September 8, 2014 And other questions to chew over, If life 'happened' by chance, at what point did it number more than just one life? And why did the first life even begin? Is there any point to it? Would not the earth still exist without it? Link to comment Share on other sites More sharing options...
Silent Trinity Posted September 8, 2014 #4 Share Posted September 8, 2014 Perhaps in the future science will allow us to discover that life began even earlier than this. Our distant history seems to be turning up as many new discoveries as our futuristic experiments that peer ever deeper into the universe...

bubblykiss Posted September 8, 2014 #5 Share Posted September 8, 2014 Quick question was it before coffee or after racism? Because that time span can summarize just about anything I care about. Link to comment Share on other sites More sharing options...
FlyingAngel Posted September 8, 2014 #6 Share Posted September 8, 2014 One question: is oxygen created by non-oxygen dependant organism or the oxygen promots the birth of organism? Link to comment Share on other sites More sharing options...
Aardvark-DK Posted September 8, 2014 #7 Share Posted September 8, 2014 Life didnt just pop up, it came from elsewhere...meteorite...comet....But, that suggest that somewhere (close or not), has life...has the life forms from the original source also evolved ? My head hurts now... Link to comment Share on other sites More sharing options...
bison Posted September 8, 2014 #8 Share Posted September 8, 2014 (edited) The article gives, in one place, the wrong figure for how much earlier oxygen became plentiful on Earth. It says 60 million years earlier than perviously thought. Examining the whole article fro IBN, it says signs of oxygen were found in 3.0 billion year old deposits. The previous oldest signs of abundant oxygen was 2.4 billion years old. That difference amounts to 600 million years not 60 million. The larger figure is far more significant. It suggests that life could have progressed much more quickly to a metabolically vigorous state, which is enabled by abundant oxygen, than was previously believed. Simple forms of photosynthetic organisms are believed to have appeared about 3.5 billion years ago. The oxygen they produced gradually built up in the atmosphere. As things now stand, it appears that it took, at most, 500 million years for enough oxygen to be produced to favor the rise of organisms requiring abundant oxygen. The opportunity for more complex, vigorous life to evolve seems stronger than ever. Edited September 8, 2014 by bison Link to comment Share on other sites More sharing options...
paperdyer Posted September 8, 2014 #9 Share Posted September 8, 2014 Yes, the age old question. Was life on Earth an accident? If not, who or what caused it and where did the who or what come from and who or what created them or it? Link to comment Share on other sites More sharing options...
Hawken Posted September 8, 2014 #10 Share Posted September 8, 2014 Perhaps in the future science will allow us to discover that life began even earlier than this. Our distant history seems to be turning up as many new discoveries as our futuristic experiments that peer ever deeper into the universe... Quite agree. And with those new discoveries history might have to be rewritten. Link to comment Share on other sites More sharing options...
qxcontinuum Posted September 8, 2014 #11 Share Posted September 8, 2014 (edited) That is exactly what i've been saying in numerous topics Mars life related that life doesn't need too much and an awful multiple zeros years to evolve. And this is just a small step ahead dealing with such unknown data In those topics i was validating the possibility that complex life might have existed on Mars until the point it had lost its atmosphere, water and core proprieties.

Capt Amerika Posted September 17, 2014 #12 Share Posted September 17, 2014 So what are we looking at? 6100 years ago maybe 6150? Link to comment Share on other sites More sharing options...
