	07:34, 3 Januarie 2021	512 × 491 (24 KG)	Jarred C Lloyd	Updated second "Snowball Earths" to be more accurate with regard to chronology and names in order to better represent the two separate events that occurred-based on current literature. Changed start point of green "Animals" line to better reflect current literature c. 655 Ma. Changed wording of first oxygenation event to better reflect current science, whereby it is the start of atmospheric oxygen increase (only ~10% PAL O<sub>2</sub>, although may be higher initially and then decrease, remai...
