He called the differ reproductive success of individuals with particular variations. A: Natural selection 6) Domain Eukarya includes A: Protists, kingdom plantae, kingdom fungi, Kingdom Animalia 7) An evolutionary tree A: Shows evolutionary relationships, Places the most closely related groups on the same branch, places the organisms that share a common ancestor on the same branch, shows the order in which populations spilt and evolved into new species 8) Which of the following statements about the changing face of the earth is not t rue?
