BIOLOGY MODULE 9 LATEST UPDATED 2024

BIOLOGY MODULE 9 LATEST UPDATED 2024 Natural Selection - organisms that possess favorable adaptations pass them onto the next generation. Name two ideas from other scientists that influenced Darwin in his work. - 1. The concept of a struggle for survival by Malthus. 2. The present is the key to the past by Lyell. If a colony of bacteria were to give rise to an amoeba this would be an example of: microevolution or macroevolution - Macoevolution, because the bacteria evolved into a completely different organism. Of the four basic data sets discussed in this module, which ones provide evidence against macroevolution? - Structural homology, the fossil record, and molecular biology. Some creationist say that all of the ideas put forth in Darwin's book, The Origin of Species are wrong? Why is this not true? - No, Darwin proposed the theory of microevolution in that book and it is a well document scientific theory today. The sequence of amino acids in the hemoglobin of a human is compared to the sequence of amino acids in the hemoglobin of a rat and an ape. According to macroevolutionists which of the two amino acids sequences should be close to the the human's? - The Ape, because according to the hypothesis of macroevolution the ape is closer in lineage to the human than the rat. How does a neo-Darwinist hypothesis differ from the hypothesis of Darwin? - Neo-Darwinism uses mutations to add information to the genetic code.
