Filling Gaps
Evolution rewritten?
Biologists organize life forms into evolutionary or "family" trees
Palaeontologists are always claiming that their latest fossil discovery will "rewrite evolutionary history." A team of scientists at the University of Bristol, U.K. decided to find out, through investigations of dinosaur and human evolution. Their study, published this week in the research journal Proceedings of the Royal Society B, suggests most fossil discoveries don't make a huge difference: they confirm, rather than contradict our understanding of evolutionary history. This is especially true of the fossil record of human origins from their monkey relatives, the investigators found. In other words, the researchers said, most discoveries of new fossil species simply fill in gaps in the fossil record that we already knew existed. Source: World Science
