Jean-Baptiste Lamarck (1744-1829), a French scientist who believed in evolution, is known for Lamarckism, or inheritance through acquired characteristics. He argued that environmental influences could put pressure on animals, making them use some characteristics more and some less, and that the changes acquired by the parents would be passed to the next generations. A common example of this theory is that giraffes could actually grow longer necks by straining to get to higher and higher branches for food, and that the offspring of these longer- necked giraffes would have longer necks at birth. We will get to epigenetics later in the class, and realize that Lamarck wasn't all wrong. But he was mistaken about giraffes! Your responses will help you understand why... (France page 7) a. Is this argument at the level of a hypothesis, or is it a theory? Why? b. How would you set up an experiment to test Lamarck's beliefs? c. What would be your dependent variable? d. What would be your independent variable?
