Top 10 discoveries of life

New Scientist published this week 'Life's Top 10 Discoveries', which is a delightful read, and included considerable overlap with my thought-content.

1. Multicellularity
2. Eye
3. Brain
4. Language
5. Photosynthesis
6. Sex
7. Death
8. Parasitism
9. Superorganisms
10. Symbiosis

I would've mebbe added embryology, and collapsed parasitism with symbiosis, eye with brain, or multicellularity with sex (although we now know prokaryotes are good at exchanging genes too).
