Document Summary

20% of the time of the planet is getting from a molten mass to a crust where life can live [hadean] Bacteria are learning how to harness energy from the earth"s environment [ they are generating high energy electrons to pass down biochemical pathways to ultimately make atp] They get these high energy electrons from methane, etc . Diversi cation of single celled protists in the oceans. There was an explosion of carbine types [all worm animals appear at once, all molluscs appear at once, etc ] Hence one ancestor didn"t appear and then things developed; it all happened at once. Insects are feeding on new organisms coming on land. Plants up until this point had been relying on producing large numbers gametes. [spores] and releasing them into the air randomly, hoping to fertilize another plant. They not use insects to fertilize other plants to make sure they will fertilize someone else by using owers.
