Sharks arose about 350 million years ago and have remained virtually unchanged for the past 70 million years and still comprise a dominant group. It is thought that sharks almost certainly evolved from placoderms, a group of primitive jawed fishes. It took a long series of successful and unsuccessful mutations with fin, jaw positions etc to give us all the different designs of sharks around today. When aske

Australia Plant Life Although only a dozen plant families are unique to Australia, there are 530 unique genera and many unique species within these genera. As the Australian fragment of prehistoric Gondwanaland drifted north, its ancient flora became the basis for the present plant systems. Increasing aridity modified this vegetation, giving much of it hardened, pointed leaves of reduced size--a condition called scleromorphy. Australia\'s native vegetation is divisible into seven types. The firs
