Timeline exercise

profileemazhin

I was asked to complete a timeline exercise on the evolution of biosphere on earth. I have attached the assignment below. I will complete the timeline myself, so I just need a list of entry of the required geological events in chronological order, add five extra events (also put in order), a brief statement of why those five are significant, and source with the required format. NEED DIVERSE SOURCES!
