Unless there is something that will knock us off all at once, then we'll just adapt to it with what we got. We would have to be down to a ridiculously low number in a bad environment for us not to explode again.

Birds fly. That's sort a massive advantage over everything. Them being 'less vulnerable' really depends on what you're talking about. Disease is something that spreads very quickly between social birds, such as avian cholera which even just this year it had 2000 snow geese dropping dead out of the sky from it.

Archaeum here, multicellularity is for fags
Making up 20% of the world's biomass is enough for now, we'll rule the world once an asteroid extinguishes all life on the surface

Fine, we didn't want to be apart of your stupid discussion anyway.

I think recent studies have shown Archaeum might actually be ancestral to Eukaryotes.
In a broad sense, Eukaryotes are advanced Archaeum who are endosymbionts with bacteria close to Rickettsia and/or Cyanobacteria.

Get lost then, grandpa.

I wouldn't even say synapsids vs diapsids
Mammals vs Archosaurs would probably be more accurate.
