Origin of Life

[Doc Dutch]

It's all there for you to re-read and try to absorb it a second time.

Awesome. You must be very proud.

Meanwhile, back to the main conversation:

I currently lean towards number two, but keep an open mind.
It would be nice if we had more intel on emergence: the transition from non-life to life. There is zero chance something as mind boggling complex as even a single eukaryotic cell just appeared on the scene without an incredible sequence of interim events. Unless we were seeded from another planetary body.

Three Possible End-Member Scenarios for the Origin of Life

1) The origin of life may have been a miracle.
2) The origin of life was an event fully consistent with chemistry and physics, but one that was almost infinitely unlikely and required an improbable sequence of numerous steps.
3) The universe is organized in such a way that life is an inevitable consequence of chemistry, given an appropriate environment and sufficient time.

Agreed. All current evidence and math points to Door #2.

It's not #1 because there's no evidence of magic or supernatural occurrences. If it was #3, we'd be seeing signs of life, even past life, within the Solar System.

There are other possibilities, not just three.

Feel free to add to the list.

Out of the trillions of galaxies you think there's only one planet that life inhabits?

Since those three are endpoints, I intellectually aim for a midpoint bewtween 2 and 3.

2.5 so to speak.

Life in the universe may not be ubiquitous. But it might not be exceedingly rare or unique either. It might just be very uncommon.

They are 3 generalities. Sure, it might be 2.5, but the options are as you listed them.

I'm still with Door #2. Maybe Perseverance will make me reconsider.

Notes I took from Professor Ahern's biochemistry class:


Sulfur, phosphorus, oxygen, nitrogen, carbon, and hydrogen account for the main six elements found in every single living organism we know of.

These elements can make multiple chemical bonds or share electrons to make covalent bonds. This is necessary for making long-chain biomolecules. Other elements abundant in the environment (aluminum, iron, sodium, etc.) cannot do what these elements can do.

Carbon's ability to make four bonds also makes it central to the construction of large and complicated bio-molecules. No other elements in the environment have the ability to from four, complex covalent bonds like carbon. A notable exception is silicon, but carbon is probably a better atom for building larger molecules. Some scientists wonder if silicon-based life is possible on exoplanets.

It's a form of the junkyard tornado fallacy.

Good answer. I appreciate it.

Nothing remotely idiotic about it. His comment indicates a perceptive understanding of the scientific debate around abiogenesis. The junkyard tornado fallacy is a valid scientific insight which has been shared by reputable scientists.

This you were obviously unaware of.

Bobbie is proud of being a 9th Grade dropout. It shows.

You think your better then others just like dutch . your both arrogant assholes. And have inflated egos and opinions of your self.
No I didnt go beyond the 9th grade because I had to worl when my grandparents who raised me got sick . I ran the farm and worked also. Until they died to pay them back for caring for me.
Yep My grammer is bad so 8s my spelling.My typing is awful
But I still managed to work on the space shuttle and eelv program . I also mananged to teach a class for a university .
I managed to work for companys like digital eqt.
So you can suck it asshole. You or dutch are no better then I am and I doubt iq wise your smarter.

Yes I went to 3 rd grade But I never got past 9th grade I had to go to work to help support my family the farms revenues were not cutting the mustard .
Yes my spelling can be poor and I dont always use the appropriate word selection.
No I got the nick name bullet bob for what I did to some trespasser on our property when I was young.
A gr Group of local dope head were partying away making a mess out of a corner of one of our fields throwing trash and damaging the field in general , then they made the mistake of threatening to beat me up. I was outnumbered 4 to one . So I went back to the house and retrieved my 3030 marlin and went back to discuss the issue with them. I put 2 rounds of 3030 into the trunk of their car to get their attention so they would know I was serious and then explained what I would do to them if I ever saw them on our property again.
I believe it induced the right response in them.
This was in my youth when I was a different person , I was young . I can look back now and regret the incident . Any other comments or questions from the grammar police ? You now get one cookie for catching me in a grammar error , good job byou also get a silver star for your paper.

I won't begrudge him a 9th grade education, if he made subsequent efforts at self improvement and to become well read.

Which obviously is not the case.

I try to keep my mouth shut on topics I know nothing about. Boob does not appear to share that practice.

Which is his major problem. IIRC, he did obtain his GED. While quitting school to work was once common, he's not that old. Given his behavior and attitude, I think he more likely quit to get that "great job" at the gas station because he didn't like "skoolin'" and liked money instead.

After 40-50 years, saying he dropped out to help his parents played better at job interviews.

yes dutch I earned a ged and went to trade schools I have worked for digital eqt ma bell , worked in a nuke plant in surry va worked on the shuttle and eelv and several small rockets and satellites among several other jobs what have you done to compare tell us all about it
