Some evolutionary milestones we discussed in class
Cyanobacteria - bacteria began to use photosynthesis and release oxygen (well-established by 3.0 bya)
Eukaryotes evolve (2.0 bya) - more complex cells begin to develop
Movement - (late-precambrian) search and find food
Body structure - (late pre-cambrian) bi-lateral symmetry, appendages and sensory organs in front
Sexual reproduction - (by 1.2 bya) combination of 2 sets of DNA leads to an explosion of life forms
