Next modern technology allows us to look inside the cells of organisms and sequence their DNA The more nucleotides or genetic letters shared by two individuals the more closely they are thought to be related Take a careful look at the individuals DNA below Determine which two are more closely related Person A A Person B G Person C A T T T CTO CAG A T C A G A A C GA G A T A A G G G Which two individuals do you believe are the most closely related Defend your answer with evidence from the diagram Direct Evidence Finally we are able to directly observe microevolution or small changes in a species over a short period of time in the world around us As new dog breeds more drought resistant crops and more infectious viruses continue to develop scientists have no choice but to accept that change within a species is possible As environments change natural selection continues to work by eliminating individuals with less favorable traits and allowing the fittest to survive and pass on their genes to the next generation
