Pre-reading1.Find out the important people mentioned in the text. Charles Darwin From England Gregor Mendel From Austria . Gote Turesson From Sweden .How many parts can the text be divided into?Part I Pa1-3: Darwin and his research.
Part II Pa4-5: Mendel and his experiment.
Part III Pa6: Turesson and his study
Part IV Pa7: the importance and significance of the research of the three.Charles DarwinGregor MendelGote TuressonFive-year expedition on the beagleOrigin of SpeciesGive birth to Science of genetics
Prove existence of stable varieties within speciesin order to adapt to the environment Species have to develop themselvesThe wild life of GalapagosConducted his experiment with Flowers and peasStudy of a
wild plant in
Swedish coastdifferences in habitat could lead to different species in birds as well as in plants.Many characteristics were passed on from one generation to the next, without influence by the environment. His research gave birth to the science of genetics.Found evidence for the existence of stable varieties within species in nature,difference between plants of one spice occurred as a result of the environment.From the research by Darwin,Mendel and Tursesson
What theory can we conclude?Both genetics and the environment are important to plantsconclusionObserve carefully wildlife on the expedition
Conduct the experiment in the garden.What can we learn from the text?Observation
