So basically what current abiogenesis hypothesis tell us is that life was originally “simple”(simpler than modern unicellular organisms) and evolved to become the complex life forms that we see today….
So my question is: where is the “simple life” supposedly eukaryotes evolve from prokaryotes but we still have prokaryotes today, multicellular organisms evolved from unicellular organisms but we still have unicellular organisms today, land animals evolved from marine animals but we still have marine animals today, complex eyes/brains/feathers etc. evolved from simpler organs, but we still have simple organs today.
So if complex cells evolved from simpler cells, where are these simple cells? Modern cells have all sorts of complex systems and molecular machinery inside, but supposedly the first cell was too simple and had none of this complex stuff.
Note that natural selection doesn’t “what” to increase complexity, NS what’s to optimize the viability of an organism, it is perfectly reasonable and likely to say that at least in some environments “simple cells” didn’t had any selective pressure to become more complex so shouldn’t there be some populations of simple cells all over the world?
With simple I mean “simple enough to have come in to existence by chance and/or by natural mechanisms.
I am assuming that your view is that ancient cells where much simpler than any modern cell if this is not your view, then you don’t have to answer.
