How Did Early Bacteria Survive Poisonous Oxygen?

Billions of years ago cyanobacteria gained photosynthesis to generate their own food from the sun. This released a lot of oxygen in the atmosphere, which should have poisoned the bacteria. Somehow, they gained the ability to resist oxygen damage.

The "Catch-22" problem is how did they evolve the ability before there was a need? Scientist feel they may have discovered the reason. picked by 2manyusernames 2 years ago

Didn't read the whole thing. Kinda just skimmed. I gets old when people push and push and push evolution when there is so little evidence and chance for it.
Evolution is basically spontaneous generation plus a denial of the second law of Thermal Dynamics plus a denial of chance and probability. It's all so delusional.

[EDIT] Just finished reading the whole thing.

Super Neat Article!

My only question would be their date of an oxygenated atmosphere at 2.3Ga, when there's quite a bit of evidence it occured closer to 3.0.. But that doesn't take away from the fact theory that a "slow trickle" of oxygen helped our primordial cyanobacteria to evolve.

It gets kind of old when people push and push for creation when there's so SO much evidence against it. I mean, how did the human race propagate if Adam and Eve only produced Cain? Not only is it delusional, it makes absolutely no sense.
