The Galapagos Islands Where did Darwin travel to? Darwin observed these animals as having an adaptation What are finches? Darwin’s important scientific theory What is the theory of evolution by natural selection? A well tested concept that explains a wide range of observations What is the scientific theory? More species are produced than can survive What is overproduction ? Lions move in on the tigers and take their home What is competition? Animals of the same species have differences among them What is variation? Individuals that have helpful traits are more likely to survive What is selection? A hawk has black feathers while another hawk has brown feathers What is variation? This is how most fossils form What is buried in sediment? The problem with the fossil record What is it has gaps? Members of a species no longer exist. What is extinction? This tells about organisms from the past What is a fossil record? Found in the seas about 540 million years ago What are the first animals? Evolution occurs slowly over time What is the theory of gradualism? These three things are used to determine evolutionary relationships What is body structure, DNA, and early development? Similar structures that related species have What are homologous structure? chimpanzees What are believed to be our most closest relative? Chickens and turtles that look almost exactly alike What is an example of early development? Pangaea What is the process of continental drift called? This leads to changes What are helpful mutations or variations? A group of individuals are separated for long periods of time How does a new species form? River, volcano, mountain range, and an ocean wave What are conditions that can separate a group from its species? The Kaibab squirrel developed from this original species What is the Abert squirrel? What are homologous structures? What is a branching tree? What is Pangaea? Who is Charles Darwin? What is an example of early development? The theory that explains the lack of intermediate forms of fossils. What is punctuated equilibria?
