when organisms share a common ancestor they share an evolutionary history todays classification system shows us that species with similar evolutionary histories are classified more closely together
how do scientists determine the evolutionary history of a species compare structure but todays scientists use info about the chemical makeup of the organisms cells
the more closely 2 secies are related the more similar the chemicals that make up therr cells and the closely simmilar evolutiuonary historues
classifications can be chaged if new info from NA come
