Complex sentence: However, the method of phylogenetic bracketing is used to infer predictions with far greater probability than raw speculation about nonpreservable traits in fossil organisms, such as feathered dinosaurs, and has also been used in molecular predictions about RNA metabolism and protein functions.
Split into simpler sentences: However, the method of phylogenetic bracketing is used to infer predictions with far greater probability than raw speculation. For example, paleontologists use this technique to make predictions about nonpreservable traits in fossil organisms, such as feathered dinosaurs, and molecular biologists use the technique to posit predictions about RNA metabolism and protein functions.
