Document Summary

Lesson 2 - chapter 25: evolution by natural selection + bioskill 3: graphs. 25. 2: the pattern of evolution: species have changed and are related. 25. 3: the process of evolution by natural selection. Scienti c theories the pattern component summarizes observations about the surrounding world the process component is the mechanism that produces that pattern. Plato came up with the idea that species are unchanging types and that variations within species are unimportant this was called typological thinking.
