Which of the following statements is TRUE about Charles Darwin? * He knew that genes played a big role in changing the characteristics of organisms. He understood that the variation that exists in natural populations of plants or animals is the result of repeated mutations. He supported Lamarck's explanation of how evolution occurred. He believed that evolution was due to the inheritance of acquired characteristics.

The theory of evolution by Darwin is a composite theory, i.e. it has five component theories: 1. Evolution as such is the simple proposition that the characteristics of lineages of organisms change over time 2. Common descent is a radically different view of evolution than the scheme Lamarck proposed. Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. 3. Gradualism – Darwin’s proposition that the differences between even radically different organisms have evolved incrementally, by small steps through intermediate forms. The alternative to this theory, as discussed in later sections, is saltation with great reference to large differences that are believed to have evolved by leaps without intermediates. 4. Populational change – Darwin’s thesis that evolution occurs by changes in the proportions of individuals within a population that have different inherited characteristics. 5. Natural selection – Darwin’s…

Darwin and Lamarck had very different ideas on how life on earth got to be the way it is now. However they had some similar beliefs as well. What four ideas did they agree on? Explain Lamarck’s Theory of Inheritance of Acquired Characteristics. Explain Darwin’s Theory of Natural Selection. Describe how Darwin’s theory was supported and Lamark’s theory was disproved.
Darwin was not the first to propose a mechanism for evolution. Lamarck proposed “acquired inheritance” in which individuals inherit those traits acquired in the lifetime of their parents (e.g., long necks). Compare Lamark’s mechanism to Darwin’s mechanism for evolution (descent with modification). As part of your answer describe how each theory is similar to the other and how each is different? Finally, Lamarck’s theory can be easily shown to be unworkable (e.g., amputees don’t have babies that are amputees meaning babies don’t inherit the acquired trait). What makes Darwin’s theory workable when compared to Lamarck’s unworkable theory.
Lamarck was an early naturalist who published his own ideas about species changing over time. He, however was mistaken about one critical aspect of evolution. If you could travel back in time what advice would you give Lamarck to correct his misunderstanding? Tell him that species actually do change and evolve over time Tell him that traits acquired during an organisms life are not passed on to offspring Tell him that artificial selection does not lead to new varieties of plants and animals Tell him that characteristics are heritable: Parents do pass on their characteristics to their offspring
What was missing in Darwin’s explanation of evolution by natural selection? How does the modern synthesis fill this gap?
What observations that Darwin made on his round-the-world voyage influenced his later thoughts about evolution?
In your own words describe the four basic causes of evolution include examples: * Mutation * Natural selection * Genetic drift * Gene flow
