From The Hallelujah TiradeThe Scientist, explaining how “chemistry begat biology,” we learn,

Sitting at the base of the three-domain tree is our last universal common ancestor (LUCA). What researchers can say today about the makeup of LUCA is a direct result of the availability of gene sequences from so many species. Aaron Goldman writes that “LUCA is not [Darwin’s] ‘primordial form,’ but rather a sophisticated cellular organism that, if alive today, would probably be difficult to distinguish from other extant bacteria or archaea.” More.

and

Are the journals already dropping Darwin?

“Sometime, Schmumble, get around to convening a meeting about how that sophisticated cellular organism ended up here. By the way, has anyone ever made a list of all the ways we used to think Darwinian evolution could happen, but it turns out it can’t?”

Comments
the second paragraph of the original article in The Hallelujah Tirade The Scientist, ends with these basic questions:
How did that happen? How fast? And where?
Then the last paragraph of the same article:
So, the scientific origin-of-life story is a biography still unfolding, not yet ready to publish in full. But learning how researchers are filling its pages is nothing short of spellbinding.
"filling its pages"? What pages? Apparently I did not get the memo.Dionisio

What did the LUCA come from? How did that happen? Where is the scientific literature that describes that process accurately, based on objective facts?Dionisio

Why would it be suprising that the last universal common ancestor was like its descendants? That's the most parsimonious scenario, isn't it?wd400

and laughed out so loud and for so long, that my wife couldn't wait for me to reveal what caused such unstoppable laughing. Finally, when the laughing diminished, I was able to show the skillfully written sarcastic style of this opening statement. Thank you. My wife said she doesn't remember when was the last time she saw me laughing out so loud for so long.Dionisio
