Primary events in the history of life

Greetings folks. This is my first time here. I'd like to get a little
feedback on something. I need to identify the ten (or so) primary
events in the history of life. The list that I've come up with is:


Hominids
Flowering plants
Vertebrates
Land life
Multicellularity (animals, plants, fungi)
Complex phytoplankton (sex)
Eukaryotic cell (cell nucleus)
Oxygenic cyanobacteria (oxygen atmosphere, primitive ecosystems)
Protocell (Prokaryotes)
Organic molecules

Any suggestions on what to add or subtract?

This is pretty important to me. Aside from soliciting casual comments,
I would be willing to pay a consulting fee to get a more careful
answer. This wouldn't be a big job, maybe a few hours. (I'm assuming
some of us here have PhD's.)

Thanks,

Martin
