Reptiles are a common example of a cold blooded organism with which most people are familiar If you have ever seen a lizard or snake in the early morning when the air and ground are cool you may have noticed how slowly they move They move slow when THEORY OF EVOLUTION. The theory of evolution is scientists explanation of how living things began. .. Also called organic evolution . LIVING ORGANISMS HAVE CHANGED GRADUALLY OVER TIME TO FORM NEW ORGANISMS THAT ARE MORE COMPLEX.. LAMARCK (1744 – 1829) . He proposed . 3 theories. to explain how species change…. Theory of Need. Theory of Use and Disuse. The Theory that Acquired Traits Can Be Passed on to Offspring.. August Weismann (1834-1914). Subject:. Biology. Date:. «date». 1.

Evolution—change in gene frequency in a population over time. Change must be genetic. Occurs in a population—not individuals. Time depends on how fast environment changes and how fast organisms reproduce. Chapter 17: Processes of Evolution. Early Beliefs. 19. th. century: discovered species shared many traits, but lived in different parts of the world. Problematic – species only looked similar on the outside, but inside were very different . and Variation . What is Evolution?. Simply… a change in living organisms over time. Why study evolution?. Evolutionary concepts provide a solid foundation to much of modern biology. - . you can’t fully understand current trends in biology or you will have difficulty understanding evolution.
