Nature's awesome craftsmanship

After watching many episodes about microbiology, I feel that life itself is a miracle, and the birth of humans is a miracle among miracles.

Sometimes, the treatment for those so-called "incurable diseases" often isn’t in the bottles and test tubes in the lab, but hidden within many organisms, even our own bodies. Life is a treasure trove, and the ever-evolving biological technology is the key to unlock it. I believe that in the near future, many "swallows in front of the Wang and Xie mansions" (cutting-edge life technologies) that were once confined to laboratories will "fly into ordinary homes."

Take DNA replication, for example. It’s probably the case that even the person who’s best at mimicking someone else’s handwriting can’t match the similarity between the original DNA and the new DNA after replication—though it’s not 100%, it’s definitely 99.999999% (don’t ask me where the tiny remainder went, let’s just say it went into evolution).

Then look at the structure of the cell itself. While it may not be as precise as some microchips, a cell is like an extremely complete and complex system randomly pieced together from what seems like unrelated matter—it’s truly a miracle, an incredibly low-probability event, and maybe it really is just a coincidence.

Some studies even show that mitochondria might actually be a type of bacteria. During the Great Oxidation Event, they formed a symbiotic relationship with cells: mitochondria used the organics in the cell to produce ATP, and the cell consumed the oxygen via mitochondria. Perhaps every cooperation in human history pales in comparison to the symbiosis of eukaryotic cells and mitochondria.

Even more striking, those special cells in sexually reproducing organisms, the "sperm," are structurally highly similar to some prokaryotes (especially bacteria), at least in appearance. Maybe this is the best explanation for "different paths leading to the same goal."

Why does life exist? That’s a question we’ve been exploring. As an ordinary person with an Lichess account, the most I can do in this field right now is learn about it.

This article reflects my personal views, for reference only, please do not use it for other purposes (especially malicious ones).

Anyone here?

I agree with your sense of wonder. However, I disagree with your description. Cells are not randomly pieced together, they are the result of evolution. If a cell were spontaneously to appear in a soup of chemicals, I would say OK, your description is right. But cells are part of a long lineage which science currently believes goes back to simple 'replicators' - complex molecules that, in their chemical environment, could produce copies of themselves.

Your description is reminiscent (probably inadvertently) of an argument sometimes put forward by creationists referred to as the 'Junkyard Tornado' (https://en.wikipedia.org/wiki/Junkyard_tornado).

"mitochondria might actually be a type of bacteria"

• mitochondria evolved from bacteria

"structurally highly similar to some prokaryotes "

• They stem from it.

By the way, our body contains more bacteria than body cells.

Before or after a shower?

"Before or after a shower?"

• Does not matter, mainly in out guts.

E. coli: Who's calling me?

It's possible that cells actually evolved from some kind of 'replicator,' but evolving from simple compounds into such a complex system is really unbelievable.

I may be wrong
Quite often i am
But i do believe mitochondria are a symbiobisosis between a bacterium and a cell
Mutually beneficial
To both

Scientists have detected sugars in interstallar space.
