Origins of Life on Earth

[happinesson]

from what bacteria did I came from? scientist are sometimes confusing.

[thegreeensky]

thats nice.. great discovry though... human originated from bacteria.. :)

I was looking at a couple black smudges under my high-power microscope.

In one,something chemical was going on,a loss of structure and function,it was degenerating

.In the other,something biochemical was going on,it was alive............

[vindarm]

These scientists get paid to do research on this crap?

[unitedfc99]

It'll be pretty sweet when we find that life occurred elsewhere. Hopefully that will happen in my lifetime. Science is getting close!!

[howthisworldworks]

I find it very depressing to believe that my great, great, great... grandfather was an ameba. Very depressing! :(

[lobban2]

@howthisworldworks

Why? He was probably one though ameba :D

[itzahazylife]

@howthisworldworks

if it depresses u, then u are too simple-minded to realize how amazing and beautiful it all really is.

[RespectMyHate]

oh evolutionist need more time. so now life began 10 of billions of years ago LOL. in a couple more years they going to say 1 trillion years.

[19raghu]

life began in India and australia,cause indo-australian plate was same until india seprated,so u cant say it began in juust australia

[00H0H00]

Why are we here??

And where we come from??

And determination to where??

Cool first life on earth was from Australia!!

[PhantomBabel]

It wasn't called Australia when it occured.

Besides if it started in Australia it wouldn't wear deodorant and would come to talk like a redneck version of British people.

[gerjaison]

What's your scientific point?

[beeDUB75]

nor can I Andy

[Arfalarf]

Stromatolites are a very poor form of evidence for the first life on Earth. When you find stromatolite "fossils" all you really find are a small mound, often just an inch or two across. No actual microbial fossils have been found until about 2 billion years ago. All this is very speculative.

Scientists need to be careful that their enthusiasm for space exploration does not compromise their objectivity.

[pontecanis]

OOOPS...here we have the advanced guard for the thought police. in Arfalarf..you will note~no attributions, plus a fallacy of Argument from Ignorance (a poor form of evidence),plus two outright lies( a small mound, an inch or two across, and No actual fossils have been found (sic) until 2 billion years ago), plus another outright lie~all this is very speculative, plus a fallacious attempt to discredit via an Appeal to Ridicule~Scientists need to be careful...in essence a worthless dissent...

[Arfalarf]

You want attributions? The textbook date for the origin of life is 3.5 gya, based on fossils in the Apex Chert found by Schopf and Packer, 1987. However, Brasier et al. (2002) showed that these "fossils" were non-biological forms in a hydrothermal system. The earliest "rock-solid", confirmed, evidence for life on earth are the microfossils of the Gunflint Chert, ~1.9 gya (Barghoorn and Tyler, 1965; Knoll, 2003).

[Arfalarf]

In addition, stromatolites ARE small mounds. That is not a lie, that is what they are. They are usually found in sediments which have undergone enough diagenetic alteration to destroy fossilized microbes, meaning that the mound the microbes allegedly built is the only evidence we have for their existence. Let me be clear about this: we are using "micro-hills" as evidence for life, without taking into account other geologic factors which could create small hills!

[Arfalarf]

Finally, let me say this.

I am not some creationist trying to discredit all of science. After all, I put the origin of life at 1.9 gya, not 6 kya! What I am is a sceptic. I believe a healthy dose of scepticism is essential to any science. That is not me being the "thought police". That is me bringing reasoned , scientific objections to a specific theory.

[gerjaison]

Lastly, i did found your comments were objective however people didn't like it, thanks for sharing info about stromatolites. I'll have a read myself.

[gerjaison]

Mate, i take notice of your references, but you see the purpose of this video was to show that they have preliminary and objective evidences that life could form around 3.5 billion year, so bottom line is they want more grants for further research on this matter.

I'm sure your references are accurate!

FYI - being an Australian UNSW is a well established university who is willing to be scrutinized by peer review.

[slywinkl]

thnx for posting :) lets hope creationists dont swoop by and try and understand whats bein said here :D

[pontecanis]

Wonderful!! Fabulous!! Having long been convinced that Cyanobaceria were the 1st

lining organisms, this is very gratifying indeed~~Thanks for posting! BTW, the evangelicofascist Brain Police may be showing up after a while...

[kritik6]

The "origin of life" and the "origin of God" are the same thing. "In the beginning, there was light." Is the "big bang" theory any different? No, it says the exact same thing. The tricky part is recognizing that God and Life are the same. The search for God, as we know it today, has, all along, been the search for ourselves.

[doGwagz]

That's great kritik. So, you're saying we find this capitalized god dude inside our head space. That seems consistent with understanding the creation of gods by mankind as anthropomorphic projections of our creative imaginations. Makes reasonable sense. God = Life!! Another great!! That would mean we don't need any of the mystical, spiritualist god thinking that religionists use for bogus epistemological authority claims.

I'm with you on this %)
