Sadly, photosynthesis is impossible for now. Just like ebbor said, the simple cells cannot deal with the free radicals and other waste products from the chloroplasts would destroy the cell, without advanced mechanisms to defend it. No photosynthesis... For now.

Certainly not oxygen. That stuff is pure poison.

We have a shortage of carbon dioxide for that anyway. So yeah, more volcanism.

((The life near the blacksmokers is quite isolated. The water around the smokers is often too cold to support life, preventing alien life from leaving it. Occasionally the warm water escaping from the smoker might last long enough for the bacteria to survive the trip to the bottom of the sea, but that's about it. The beings at the bottom of the sea will be anaerobic, feeding on the chemicals that escape the smokers))

Yeah, so overrated anyway. Especially its byproduct, ozone. Overrated. Anyways, you can never have enough carbon dioxide, can ya?

I feel somehow inadequate against the creative minds of this forum all of a sudden.  This, while I can understand it, is beyond my ability to create...  :-[  :o

Don't worry, it won't stay this complicated if that's your problem. Once we get from the cell level, it'll get simpler.

The water around the smokers is often too cold to support life
I was first shocked to read that, knowing water can reach 180°C there, but then realized you meant the water between there and the surface. Which is completely untrue IRL, but probably true for our fragile, tiny specks of life.

I support the rest of your post. No oxygen for now (it's a waste product we got used to, nothing more), more CO2 (it being food source) and black smokers life being anaerobic and chemiotrophic.

I will now steal this tree of life and add my favourites. :D *excited mode ON*

EDIT: The Cometborns, having suffered through a thousand lightyears before getting to a relative rest on this planet, earned the ability to harvest deadly radiations, and turn it into useable energy. This marvel of survival is done by them having lots of redundant RNA strings that shield the useful bits, and get broken down by the radiation, then repaired. This endless cycle produce an energy output that keep the cell alive. Cometborns turned deathly rays into feeding light.

Interesting way of life you have there. I like your originality.

((Repairs cost energy, they don't produce it. Besides, radiation levels will be far to low for that to be feasible anyway))

Well, there is no ozone and basically almost no other protective layers in the atmosphere. Well, there's the magnetic field, but it can't block all of it.

"Say, the sun is firey right? Screw it, we don't have any gods of light; I'll take up that burden."

Grant one of the comet-borne prokaryotes photosynthesis.
Once that prokaryote becomes established, fiddle with some of the soupy prokaryotes to help them engulf smaller cells in a symbiotic fashion.


"Could be patient. Don't feel like it."

For reasons I stated before, that won't work until the cells get more advanced ways of dealing with the dangerous stuff coming with photosynthesis.

Wait, we aren't?

Well, we are still at the prokaryotic level. These simple cells are basically just a storage for RNA (a simple nucleus) and a membrane. Not much more, yet.

Due the constant radiation, some of the prokaryotic cells degenrate, losing some of their RNA-Code. They are now not able to live alone, so they start to "infect" healthy prokaryotic cells with their broken code, forcing them to produce more of these broken cells.

Prokaryote does not imply RNA.

I know, I was pointing out that prokaryote does not necessarily imply that they use RNA.

Cilia...Amoeba...
So wrong.
I still understand what you mean, though.

Derp.  The answers to life are apparently on this very pimped out page...

The current prokaryotes are either amoeba or just go with the flow of the water...

"true" amoeba are eukaryots, just saying.
Also the free radicals come from O2 respiration, not photosynthesis. And a single enzym, degrading H2O2 into H2O and O2, resolve the problem quite well. Otherwise, just dump it out. For small primitive bacteria it should be fairly simple (eukaryots are 10 times bigger and have their free radicals produced deep inside, while bacterias have them on the external membrane.

I assumed he meant that they used pseudopodia to move.

I'm still giving them more advanced chemistry first.

Photosynthesis will cause free radicals as well as O2 respiration.AFAIK. However, the problem still remains that photosynthesis is impossible without compertamentalization.

Anyway, my action. As a side effect from the now persistent virusses amongst the Deep creatures, other things started to happen. Even adult/ healthy cells started to temporaliy merge with each other, periodically sharing genetic information before parting again.

Cyanobacteria do compartimentalize. They just fold up their own cellular membrame.
