Lamarck vs Darwin

Q How do the evolutionary models of Jean-Baptiste Lamarck and Charles Darwin differ? Use at least one example of an organism studied by each of these scientists in your discussion. Which scientist was correct? (NOTE: in order to compare these models, you will need to briefly summarize each one. Certain key phrases, such as the descriptive names given to each model, are necessary in order to receive full credit!) Additional note: Please be sure to remember that, in discussing the work of a scientist, it is not appropriate to use the word "believed" (e.g., "Lamarck believed the moon was made of Limburger cheese.") Science is not about belief, but empirical observation and demonstrable fact. Also please note that in order to be considered a "theory," a model (or hypothesis) proposed by a scientist must be supported by empirical testing over and over again, and never refuted. One of these models has withstood the test of time, and the other did not. Please be careful how you use the word "theory" in your essay, if you use it. PreviousNext

Jean- Baptiste Lamarck and Charles Darwin were both naturalist who differed in their observations. Lamarck postulated an important theory that characteristics are acquired via inheritance. He even developed an early theory of evolution involving the inheritance of acquired characteristics. According to Darwin physical characteristic play a crucial role that enhances an organism’s ability to reproduce and survive. He concluded that adaptation is the main cause of evolution. Darwin’s theory was called the theory of evolution by natural selection.
