No. Testing old rock samples gives a pretty good indication of the environment in the past. That's what the experts use to determine the chemical content of the experiment, but to be very blunt, abiogenesis set-ups aren't actually that difficult. When my biology professor was a high school teacher, one of his students made such a set up himself. The materials within the experimental conditions aren't rare; the hardest part would be producing the spark or consistent heat source, and certain old car parts work for producing a spark. You just use heat to keep the environment free of living organisms.In state of the art labs designed by experts. Likely is code for guess.
Nope, introducing macromolecules such as RNA would ruin the experiment, and introducing living cells defeats the purpose entirely. Even amino acids, basic carbohydrate monomers, nucleic acids, some lipids... all which form naturally in the environment all the time, aren't introduced to the experiment and are allowed to form within the experimental environment instead. As basic as it gets. If you want to run an abiogenesis experiment yourself, I'll gladly give you direction on how to do it. Heck, if you know anything about making glass, that could save you some money you'd have to spend on the set up. What you'll need for the atmosphere is water vapor (easy to get, since water is going to evaporate in the experimental conditions anyways), hydrogen gas (I'd just buy a small amount with a high purity), ammonia (you probably own some of that for cleaning purposes, but you might want to buy a small amount with a higher purity than that), and methane (which is also easy to get). If you feel like doing it, I'll give more instruction. You'll start to get amino acids, lipids, and basic sugars within a month. If you keep it up, you'll start to see lipid bubbles (basic cell walls) fairly quickly too. Unfortunately, basic life takes years to form in these experiments, and since I don't know your age, I am not sure how feasible it would be for you to keep the experiment ongoing for a decade or more.So what do they (intelligent agents) introduce? RNA? Cells? That means they already start with really complicated things, not raw chemicals alone.
-_- just because some things on this planet, such as cars, aren't naturally occurring, that does not mean that all things on this planet must be created. The reason why cars aren't natural isn't because of their complexity (arrowheads aren't natural either, mind you, and they aren't any more complex than a rock). It's because natural processes don't produce cars. Thus far, evidence strongly suggests that life can be produced through natural processes. Does this inherently mean life on Earth was necessarily produced this way? No, it just makes it a possibility. If not here, then perhaps elsewhere in the universe. However, with no strong evidence for a creator, stating that life on this planet must have been created is jumping the gun.Right cars require intelligent agents and a state of the art factory. If cars are unnatural then so is bio life here because both require the intervention of a living intelligent source.
-_- why do you continue to insult me by suggesting I am making stuff up? I offered to give you sources before, but you never requested them. I gave you a name to Google search for yourself if you wanted. I'm going to put some sources in my post wherever they fit best.That is following the evidence based on everything we know about life. Not Ad Hoc rescues or making things up.
No, the premise is "Once on this planet, there was no life. Thus, life had to get here somehow. Let's utilize our understanding of the ancient Earth conditions, and see if life will naturally begin to form." In all honesty, I don't think they were expecting results so quickly.More guesswork and starting with their conclusion. Life somehow arose thru natural nonintelligent processes. That is their start.
-_- how? Abiogenesis experiments are models of the ancient Earth environment left to sit for years, with samples of the contents examined periodically. A biosphere that starts out without any life in it. The simple cells form. Since the very basic life that forms within these experiments DOES NOT EXIST IN THE NATURAL ENVIRONMENT CURRENTLY, it is impossible for contamination from living organisms to be the source of these very basic, RNA based cells. Chemical tests for amino acids are really easy to do, as are the ones for simple sugars and nucleic acids. I've done them myself, they don't even take an hour out of my day.They can then retrofit their starting assumptions around their scenarios, read, guesses. They do not follow the evidence, they fit the evidence into their senarios. If they are looking for the first cause of bio life they are looking for a living cause.
-_- I've watched cells duplicate. I've seen every stage of cell division. Cells mess up with it quite a bit. There are so many chemical controls in place to halt cell division and kill cells that divide incorrectly because this natural process is so flawed. This is why cancer happens.We die and they may die but they can duplcate. Cars or Xerox machines do not naturally duplicate and neither do cells. it is too complicated a process to happen naturally. If you think cells can naturally duplicate then you really do not know what you are looking at in the first place.
Feel free to talk whenever you like, in an appropriately themed thread.Maybe later when i have more time.
-_- of course when you break a cell apart, the organism dies. We aren't trying to create life by hand in abiogenesis experiments. The point is to let it form. Cells are the smallest unit of life. The earliest life, thus, is going to be a cell. Of course, modern cell organelles are quite developed; they've had billions of years for that.No known ancestors to bacteria and when they try to break bacteria down the organism dies.
Now, let's discuss what makes a bacteria a bacteria. They have a cell membrane, and no membrane encased organelles. Cell membranes are just lipid bilayers (they'll form spontaneously in disturbed water) with proteins sticking out of it (get trapped in the membrane as it forms). These actually form fairly early in abiogenesis experiments, and as they get bigger, they begin to separate and divide into two smaller lipid bubbles. Bacteria have ribosomes, which consist of RNA. RNA does quite a bit of work in cells, as they serve to translate DNA and build proteins. Bacteria also have their genetic material, which isn't membrane bound and forms rings (unlike our linear DNA). Then, there is the cytoplasm, which is the internal environment of the cell as a whole, and is affected by the outside environment. The cells produced in the abiogenesis experiments also have all of these things, aside from their genetic material being RNA instead of DNA (Has uracil instead of thymine, and ribose in the sugar phosphate backbone instead of deoxyribose, the difference being that deoxyribose has 1 fewer oxygen atoms than ribose). "But Sarah, why don't we have RNA as our genetic material instead of DNA if the first life used RNA?" An ancient cell messed up and produced proteins that produce DNA instead of RNA using the nucleotides in the environment. As it were, DNA is far more stable than RNA, so the offspring of that cell actually reproduced better than the RNA competitors.
-_- duh, because the precursors to bacteria weren't like modern bacterial cells minus parts, but rather they had the same essential parts in simpler form. You aren't going to get that from bursting bacterial cells.You do not get simpler life, you get death.
Not really, the chemical processes that formed life are actually pretty basic. Most of them happen in various places on Earth still, and the biggest reason we don't see life form all the time is because early life is made out of the same stuff modern life likes to eat, and cells in the process of forming have no hope of competing with organisms that have billions of years of development on them.From chemicals to bacteria is far more complicated than bacteria to humans.
It is well beyond conjecture when it has been repeated in lab, and science has nothing to do with magic (except for debunking claimed instances of it, I guess). Life is chemicals fueled by chemical reactions. There's no mystical life force to be found, no process within cells that defies nature.Ancestors to bacteria are all imaginary as is the magical primordial soup etc. It is all conjecture.
It is an overstatement. They are no where near and they say so. They may over exaggerate their results for funding purposes. No different in principal than a Benny Hinn healing service. Both con jobs designed to excite the gullible and true believers. Whip them up into a frenzy. I like that analogy. Benny Hinn and origin of life researchers have a few things in common.
New Szostak protocell is closest approximation to origin of life and Darwinian evolution so far
https://molbio.mgh.harvard.edu/szostakweb/publications/Szostak_pdfs/Adamala_Szostak_2013_Science.pdf
The former is about this scientific publication and an easier read.
Liars in the scientific community are weeded out very quickly, as one of the demands of the scientific process is that the experiment and its results must be able to be replicated. No singular group is relied upon to be honest.
-_- it's really not that complicated, nor does it need to be. Modern cells just have a directed replication that the protocells do not (they just end up dividing into two cells whenever they reach a certain size). It looks really complicated in diagrams to people that don't know what they are looking at. Heck, the only item that is distributed entirely evenly to daughter cells upon division is DNA (when the cell divides correctly).Garbage. It has always been valid. If you find the Starship Enterprise on the moon then the cause is not the moon but a source extrinsic. Same with bacteria. Natural processes chemical reactions did not produce bacteria which duplicates. The process is way to complicated.
Step 1: the cell grows
Step 2: the cell replicates it's DNA
Step 3: the cell grows some more
Step 4: The cell divides, with each copy of DNA (in the form of chromosomes) being pulled to the far ends as it does so by protein fibers that attach to them and gradually shorten. I could go more into depth if you like, but every part of the chemical process is well known and not supernatural or magical or miraculous.
Even if life on this planet had a creator or had some quality of it that demanded a creator, that wouldn't indicate the nature of the creator (or multiple creators). It wouldn't even mean that said creator/s still existed, much less that they were a deity (and a specific one at that).Life here is the evidence for God. It would take an intelligent source extrinsic of the universe and timeless and that is God. Absent God, we would not be here.
As it stands, there's nothing about life on this planet that actually demands that it was created, as far as our understanding of the functions and formation of life goes.
If that were the case, then far fewer kids growing up in religious households would later be religious adults. Also, I understand why the argument from complexity exists. It's just inherently flawed because complexity isn't an indicator of something being created. Many simple items, such as a slingshot, are created by us. Plenty of complex items, like a large underground cave system, form naturally over time. Since complexity is not an inherent quality of created items, it's a pointless argument to make. That, and the fact that something being complex doesn't exclude it from having a natural cause.Perhaps it is like advanced math. You either get it or you don't.
By the way, whether or not you consider something "complex" is subjective ;P
You were suggesting I should be a nihilist, as if I had no choice. I found that really, really funny. I'm open to being converted, but I am not open to your implication that being an atheist demands that I think all my actions are pointless and be depressed about it.That shows sarcasm and ridicule and not a degree of openess you claim above.
Convince of what? I try to convince myself that there'll be something after death quite a bit. Unfortunately, I consistently fail. Otherwise, I suppose that I've been trying to convince you that I'm not pulling scientific progress out of my proverbial anus -_-. Not sure why you hate on abiogenesis so much, since it's entirely irrelevant to whether or not deities exist. Even though life can form naturally, I don't see why you couldn't believe that a deity guided the formation of life on this planet anyways.So who you trying to convince?
Actually, I've given examples of what would convince me of the existence of deities before, even without direct exposure (I definitely hope you don't think I am so obtuse that I wouldn't believe in deities as I was looking at one). For example, an individual book that can be read by anyone, even the illiterate, and everyone gets the exact same meaning out of it. I don't even care if this individual book was philosophically interesting or not, it could be a cook book, but I would consider an individual book that breaks all language and ability barriers to be a miracle. And I am not talking about a book on tape or one translated into many languages, I am talking about a singular, physical copy that accomplishes this.When it comes to God your mind is slamed shut and no amount will ever convince.
Abiogenesis is fascinating, but a deity creating life is far more so. The former just has more evidence supporting it at this point in time.Also you will cling to your alternative creation myth, no matter how preposterious, inferior and counter to all we know about life and living things.
*sigh of relief* so glad I am not debating another flat Earther or a person that believes the physics of the past were significantly different from those of the present. Those really test my patience and sanity.If all life has an exclusive nonliving first cause (blind faith) then the spherical Earth came from a flat Earth and the present has zero to do with the past.
Also, abiogenesis doesn't suggest that life exclusively has natural origins, just that it is a possibility for life on Earth. I mean, we engineer goats to produce insulin in their milk for diabetics; those goats are hardly "natural".
-_- Darwin hasn't be the authority on evolution for more than 100 years. When theories are first made, they generally get a lot wrong. After all, the original atomic theory just had atoms be solid balls of mass. What a guy got wrong in the 1800s is irrelevant to the successes or the failures of modern day.So much for Darwin who assumed change in his present retrodicted to change in the deep past. Can't have it both ways.
