Bio1130 jon houseman: final exam study notes. 550 million years so far, we have spent 2. 3 billion years on this planet, and so far, we have aerobic bacteria, anaerobic are still there but hidi(cid:374)g i(cid:374) pla(cid:272)es (cid:449)here the(cid:455) are(cid:374)"t poiso(cid:374)ed (cid:271)(cid:455) aero(cid:271)i(cid:272) e(cid:374)(cid:448)iro(cid:374)(cid:373)e(cid:374)t (ie: ocean trenches). Cenozoic (65 ma to present time 72nd floor) Paleozoic (550 245 ma, 63rd to 65th: cambrian (550 488 ma, ordovician (488 443 ma) Multi-cellular ingestive heterotrophs (animals) make their appearance. Soft-body organisms of animals dominate: silurian (443 416 ma, devonian (416 359 ma) First algae cells are going to make multicellular structures and come up on land by being at the water-air interface. They will become effective at doing a number of things: mosses, ferns, etc. The insects will also come up on land with them as they munch on these spores, leaves, vegetation etc.
