| SYDNEY, Australia - Giant prehistoric kangaroos and wombatlike creatures the size of hippopotamuses were not killed off by human hunters but by climate change and starvation, an Australian study has found. The study, based on the re-excavation of a site at Lake Menindee in western New South Wales state, found strong evidence that the cold climates of the last Ice Age were followed by a drought which caused the mammals to starve to death. The site was first studied in the 1950s, when scientists argued that hunting implements found there meant that humans had killed off the giant beasts. |
