One in a million, or billion, chance, is still a chance. The chemical that interacted with one another that ultimately led to the formation of DNA had not one interaction, but a few hundred, maybe million billion interactions. So the formation of the first DNA (or RNA) is not actually surprising.

Comparing it to a pen, paper and novel is not appropriate because the DNA did not form from a one off reaction. It most likely formed one after the other. Eg: Bases formed, then other bases, then the Hydrogen bond, then the helix etc.

The more appropriate analogy would be to drop the pen on a different paper several trillion times, then rearranging those strokes created in several trillion different ways, and there ought to be at least one or two of those arrangements where there is a recognised word formed.

But then, why right now, there was no new forms of DNA?
I mean, there's no prove in the real world that chemical reaction can create a new DNA for a primitive cell.

Well, the interaction creates an amino acid. But, there's no prove that amino acid can evolve into a primitive biological cell.

you just read the first paragraph, didnt you?

This experiment inspired many others. In 1961, Joan Oró found that the nucleotide base adenine could be made from hydrogen cyanide (HCN) and ammonia in a water solution. His experiment produced a large amount of adenine, which molecules were formed from 5 molecules of HCN.[12] Also, many amino acids are formed from HCN and ammonia under these conditions.[13] Experiments conducted later showed that the other RNA and DNA nucleobases could be obtained through simulated prebiotic chemistry with a reducing atmosphere.[14]
and this was in reply to your query

i dont think we evolved from monkey....

it is impossible duh.....

if monkey can evolve into humans...then why do monkey stops evolve when human existed???

the theory is unreasonable...dont u think????

the original species may survive when a new species emerges and continue to evolve along two separate paths,this is the basis of evolution...
and large scale evolution takes a very long time to achieve,it's not like a cell can become a human overnight... wink.gif

human do not evolve from monkey, they come evolve from common ancestor with monkey.

I believe in theory of evolution but not 100% of it.
I don't believe humans evolved from apes..
As far as i know, scientists still haven't found the missing link between ape and human, i mean the fossils..

another 'missing link' approach... doh.gif

Well for what I know, Since the environment is currently to our advantage, our physical traits would evolve to 'suit' the not so demanding environmental situation (in terms of physical movement) that we have succeeded in producing.


However, I do believe in one part that would continue to evolve to something better (assuming a perfect modern world we live in without disease and such) is our mental strength. Our brains would evolve to think harder, to be able to compute complex theories but not being able to compute multiple calculations (thanks to the invention of the calculator)

Hmm...

If you found A & C, the in between is B which is the missing link, anything could happen during that time to the vulnerable homo species comparing the physical build and are likely the last in the food chain.

Zoology / anthropology begins with theory at first and its progress is slow due to the dependence of hard evidence and technology to unveiled the secrets from any remains, water are found in the “Star dust” project collected from the trail of a comet suggests that live may actually begin from elsewhere.

Each human is highly capable to learn & mimic from the generation before but our brain’s recording and analyzing abilities is limited, so it is the specialized individuals who work and archive the enormous amount of knowledge where ordinary people only scratched the surface than really understand.

Evolution changes everything and everything came from something, there are all kinds of minerals and pollutants in our system that we share on Earth, crocodile has the strongest antibody known to science and they live for so long keeping its features than evolve into something else.

So, if human only need technology to continue living, the physical appearance will remain and maintain by exercise or else will really change shape in less than one lifetime.

and when you find B, they would be asking for 1/2A-1/2B; then 1/4A-3/4B and so forth.....

Is there a flaw to simulate what is B from A & C regardless of portion?
We are the living proof of the result, or you are implying we are created by god from Adam & Eve? how many percent of science is around us than god's presence? PHD is a doctrine of science.

In my industry, programmers have decoded light & shadows into software including physic simulation that can only be captured with camera in less than 40 years, the progress is based on facts of the past contribution and the same methodologies goes to all sectors until today. Look around you, is there anything you can make? If not, what role do you think you play in the science process?

In here science is hard proof that accumulated from at least 2 thousand years of recorded history to allow us communicate in cyberspace, it is everything to make schools and educate us to become the person we are today, absolutely non fiction.

I don't know why... I believe we "humans" are "aliens"... tongue.gif

Wait... hold on.

See, I believe a certain ancient civilization once ruled the Earth (e.g Sumerian civilization). These "gods" were what we would call "aliens" from outer space. These aliens found Earth way back in time and found life on it, and wanted to exploit the resources on it. So, what they did is that they mixed their genetic code with one of the species on Earth to carry out their bidding - - perhaps one from the chimpanzee/ape species.

Then, we "were formed". A genetically modified "alien". Thus we begin our roles as slaves. For a long time, it seems fine. Until these "aliens" decide to leave and monitor from time to time the labour work of mining, say, gold for example.

But we grew too quickly. Multipled too fast. We were forming our very own civilization. We formed... the "human race". These aliens kept monitoring us and decide to leave us on our own. And that's when things get slighty eerie. From time to time these aliens would "abduct" a human specimen to see how much of them is left in us. Animals too - - but they are mutilated/killed because to these aliens, they have no value. They just want to know the "quality of the environment" by checking out the innards of the animals.

Well.

Then it goes on and on for thousands of years.

Until today, UFOs are flying around. Fact: Google search "UFO", and up pops up a news or more about an eyewitness. Abductions occur more often, but these abductees memories are erased thus difficult to trace whether aliens or just self-injury.

Until "the day" arrives, perhaps when Nibiru approaches, their mothership stationed on the rings of Saturn will move towards Earth and "ferry" some of us away. "Rescue" is what they say. But... I think not. nod.gif

How bout that.

It could be plausible, but likewise for every argument comes with solid evidence to support it.

This goes under Scientology. And what part of 'evolution' does your argument bring?

Dude... there are plenty of sources about Sumerian gods being the grey aliens we humans "encounter".

Here is Part 1 (of 8) of a long journey into this matter..

The latest Hollywood flick to "hit" my theory right in the centre is the movie called "The Fourth Kind" (2009). Google it.
