Recall the processes that lead to the Great Oxygen Event & how earth looked
before and after this event - Cyanobacteria evolved photosynthesis which created
O2 as a side effect which lead to Great Oxygen Event
Before: all organisms heterotrophic prokaryotes
After: Set the stage for geology and biology as we know it today
Assess the different outcomes of the great oxygen revolution regarding their
consequences for life on earth and for earth's geology and atmosphere. - Minerals
formed
□ Banded iron ore
Ozone layer formed
□ Protection from UV-light
Free O2 is toxic to cells
□ Led to global mass extinction
O2 reacted with Methane (greenhouse gas), removing it from the atmosphere
□ Led to snowball ice age (2.4-2.1 bya)
Some prokaryotes evolved ways to use O2
□ Leading to evolution of cellular respiration
(later) Eukaryotes with chloroplasts
□ More effective photosynthesis
□ Even higher O2 levels
□ (much later) Evolution of multicellular life
Generated new niches
□ opportunities to diversify
