Document Summary
Unit 9. 5 homo erectus erectus to floresiensis. If you"ve got at least one male and female that reach a new place they can repopulate new places. Helens and 933 times stronger than pompei: some say this volcano was the reason for the last ice age. If you"ve got an enclosed ecosystem like an island, you got plants and animals and if there"s not many predators then the individuals relax and don"t need big bodies. We developed our stature to defend from open land predators if you"re not that worried about any predation then you can just grow small without a major tradeoff. There"s no large predators here the biggest one being the komodo dragon so you"re free to evolve a small body you can maintain your resources better with a small, less expensive (energetically) body. There"s also living examples - sumatran rhinoceroses is 1/3 the size of the african ones.
