Life became much better for algae. So yes.

No. They killed themselves off to near extinction several times as the planet repeatedly froze over.

Can you explain this to me please?
M understanding is that photosynthesis takes CO2, binds the c to the plant and emits O. (Basically)
How does that lead to extinction of algae? Like, depleting the carbon resources?

The Great Oxidation Event had atmospheric greenhouse gas levels plummet, which resulted in the young and comparatively weak sun not being able to keep the planet warm, resulting in the Huronian glaciation.

No more CO2 means no more greenhouse effect. Everything froze, and you can’t do photosynthesis well through a thick layer of ice, so the die, CO2 gets released as they rot. Maybe some large volcano erupts, things thaw again and they repeat the cycle.

Damn, I didn’t realize algae was so fucking stupid.
