1.3 Transitional fossils A transitional fossil is any fossilised remains of a life form that has traits common to both a presumed ancestral group and its presumed derived descendant group. Transitional fossils are used as evidence to support evolutionary theory as they are suggested to demonstrate the gradual transition from one species to another through a multitude of changes. In essence‚ the transitional fossils are the remains of the species that have gone extinct‚ and these species are represented

Hydrogen: The Fuel of The Future By: Json Why are we as Americans so afraid to change? even if it is a change for the better? the world has been using oil coal and other petroleum products to power just about everything that moves for the last 150 years. yet most cars in the united states only get 10-20 miles a gallon and even the "good" ones can get only a petty 20-50 miles a gallon. so why do we put up with the inefficiency when there are far better alternatives out there? Such as hydrogen
