Well there are a lot of mind boggling questions about abiogenesis in my mind that I can't put it in words very accurately.But the one that I can say is the following: Is the simplest life form ever known to man irreducibly complex, according to current understanding of biology?And in what point could the structures be called life? Is there any scientific theory that states that life is a property of all matter(because I sometimes tend to think likewise!)?

Pray. You will get your answer, my friend!

>> No.4198811

yes he is right, you should pray, as I did, the answer is simple

God IS life!

Do excuse /b/, OP, they are filling our board of 65% religion threads to 100% religion threads.
Life is not a property of all matter of course - rocks are not alive, yet are also composed of matter?
I recommend reading more textbooks.

Actually the simplest form of life is something we've seen form by itself many times, there's just a lot of bitter debate as to whether it's appropriately classified as life:

Well, firstly, You should know that the 'primordial soup' that the early earth had had everything needed for making life in the form of DNA, the first replicating molecule. The atmosphere consisted of a variety of gasses including hydrogen, hydrogen cyanide, methane and ammonia. Being as it is that DNA is formed from just 4 different types of nucleotide, we ask 'how did these nucleotides originate?'. Well, If we leave Hydrogen cyanide and ammonia to stew in an aqueous solution, in an environment very similar to early earth, we get one of our nucleotides when you add a ribose and phosphate group. The other 3 are thought to have been produced in a similar way. The next step is polymerisation, the joining of nucleotides. Montmorillonite, abundant on the sea floor of early earth, was the perfect catalyst for this reaction. we now have RNA (Ribonucleic acid) which is a polynucleotide that can make copies of itself. These copies aren’t always perfect (hence evolution), these imperfectly copied RNA molecules get a trait which allows an affiliation with lipids. These lipids create natural spheres in water-based solutions. RNA that attracted lipids would find themselves protected in a phospholipid bi-layer. This is the first primitive cellular structure. It replicates and passes on the traits of affiliation with lipids as well as new adaptations being brought about by random mutation. And the rest, as they say, is history. Sorry for the long answer, but no religious person could have told you that.
Picture slightly related.

There's no such think as irreducibly complex. Not in Biology, not in Logic, nowhere in science or rational thought.

There's your question answered: the question itself is flawed.

>> No.4198883

>>4198794
As far as I know, yes. But that is primarily due to the definition of life. There are several simple systems known that display life-like properties without displaying all qualities necessary for it to be called alive.

One example are vesicles that absorb surfactants and undergo blebbing when they have consumed enough surfactants have been consumed, which is an example of a system displaying consumption of resources and reproduction without reacting to external stimuli.

Nope.

Anyother questions?

WTF are you answering "yes" to? Life is not "irreducibly complex" and all matter is not "alive".

Stop trolling
