Summary:
Hot vents on the seabed could have spontaneously produced the organic molecules necessary for life, according to new research. The study shows how the surfaces of mineral particles inside hydrothermal vents have similar chemical properties to enzymes, the biological molecules that govern chemical reactions in living organisms. This means that vents are able to create simple carbon-based molecules, such as methanol and formic acid, out of the dissolved CO2 in the water.

This is more evidence that the building blocks of life were likely present and forming in these environments before life emerged on Earth.

What our research proves is that these vents also have the chemical properties that encourage these molecules to recombine into molecules usually associated with living organisms

Here is another recent article describing how primordial DNA could have formed spontaneously:

New study hints at spontaneous appearance of primordial DNA -- ScienceDaily

The self-organization properties of DNA-like molecular fragments four billion years ago may have guided their own growth into repeating chemical chains long enough to act as a basis for primitive life, says a new study by the University of Colorado Boulder and the University of University of Milan.

The Miller-Urey experiment created more of life's building blocks that they realized when the experiment was first conducted:

Lost Miller-Urey experiment created more of life s building blocks IU News Room Indiana University

BLOOMINGTON, Ind. -- A classic experiment proving amino acids are created when inorganic molecules are exposed to electricity isn't the whole story, it turns out. The 1953 Miller-Urey Synthesis had two sibling studies, neither of which was published. Vials containing the products from those experiments were recently recovered and reanalyzed using modern technology. The results are reported in this week's Science.

Feldspars are also known to help create double lipid layers. Either, at a tidal layer would get the requisite wetting and drying. From the differant articles I have read, it is not how was abiogenisis possible, but which of the many differant paths possible did it take here on earth, and what differance did that make in the outcome?

Another interesting discussion on this topic.

....and yet the math of these simple molecules forming a single cell renders it a physical impossibility even over 4 billion years.

The odd of 2,000 of these molecules bouncing around and aligning themselves to form a cell USING ONLY LEFTHANDED AMINO ACIDS are a number with almost 6,000 zeros to 1.

 

[CrusaderFrank]

Now, Frankie Boy, go post about something that you 'know ' something about, like your hollow moon. LOL

Did you know that life on planet Earth uses only left-handed amino acids? If there's an equal chance of these amino acids reducing out of your primordial soup, the right handed ones are a dead end.

Please explain the process by which life forms form only left-handed amino acids or are you a left-handed amino acid denier?

 

[CrusaderFrank]

Now, Frankie Boy, go post about something that you 'know ' something about, like your hollow moon. LOL

Like every other time you've done it, insulting me does not correct your fundamental misunderstanding of how the world functions.

How badly must it suck that there's far more real scientific evidence that the Moon is an artificial sphere than there is for manmade global climate warming change disruption or whatever you're calling it today

Think life starts pretty easily where ever chemistry is favorable to it. Intelligent life on the other hand using Earth's example is exceedingly rare.

I suspect planets are teeming with life all over the universe. But intelligent life seems something of an accident. Of course the law of large numbers is on our side and even a freak occurence as happened here could happen millions of times across the whole universe.

But if is just random chance and molecules bumping into each other, every planet should have evolved self aware life, or are you saying that the other planets are much younger than Earth?

Just because we currently have only one point on the graph doesn't mean that that point is exceedingly rare. After all, as Sagan said, "if it is just us, seems like a waste of space". There is a lot of space left to explore.

Is likely simple life on at least 2 other Sol system planets and moons. But looking at us and chimpanzees, we evolved technological intelligence, but nothing else has despite some species being vastly older with similar brains (bottlenose dolphins, other primates.) Some species use simply tools like sea otters and primates, and I just saw video yesterday of a dog displaying problem-solving intelligence moving a dining table chair next to a counter to get up there and get the chicken nuggets in a toaster oven. But it could have been trained to do that too.

Bottom line is the universe is about 14 billion years old, and technological life (us) came about in less than 4 billion. So there's probably other intelligent technological life in the universe. But it may be few and far between, while life as with plants and simple animals exist throughout.

Actually, there are several other species that use tools. Some species of crows, for instance, not only makes and use tools, but can use them to get other tools to accomplish a task. And you don't have to make a tool to exhibit intelligence. The African gray parrot is one of the most intelligent animals around, and the cool thing about it is that you can actually talk to it (granted, it's like talking to a two year old), but unlike apes, it can talk back.

Some species use simply tools like sea otters and primates, and I just saw video yesterday of a dog displaying problem-solving intelligence moving a dining table chair next to a counter to get up there and get the chicken nuggets in a toaster oven. But it could have been trained to do that too.

It takes intelligence to accept training.

Bottom line is the universe is about 14 billion years old, and technological life (us) came about in less than 4 billion.

On earth, you mean. we have no idea what is out there. For all we know, there is intelligent life that has been around for far longer than we have been around. And likely far more intelligent.

So there's probably other intelligent technological life in the universe. But it may be few and far between, while life as with plants and simple animals exist throughout.

I don't think they are uncommon, I just think they are too far away for us to ever interact with them.

I just researched it. Turns out it hasn't happened. That's so scientific of you to believe in something that has never actually been observed. You logical people you not believing in magic.
