Answers to Study Questions 1-1 I’ve not included answers for questions that have not been completely answered yet. 1. Some would argue that the “Ladder of Life” or “Great Chain of Being” proposed by Aristotle and other early natural philosophers is “teleological”. What does this mean? Teleological refers to an idea or a statement which expresses a goal or a final endpoint. According to Aristotle and other early philosophers, the evolution of species had a final goal. This final goal resulted in evolution ending with the development of humans. Aristotle developed Plato's concept of essentialism into the idea that species have fixed properties. Christians later took these ideas and determined that God's creation followed a plan from inanimated objects through higher forms of life. They determined humans are both physical and spiritual and must be the final creation of God. Therefore, the "Great Chain of Being" was determined to be permanent because any change would imply imperfection in God's creation and that humans are not the final link between the physical and spiritual world. 2. As discussed in class, the blacksmith’s son often has large muscles even before he has taken up his father’s profession. Explain this phenomenon in terms of “inheritance of acquired characters. A blacksmith's son often has large muscles even before he has taken up his father's profession, in terms of "inheritance of acquired characteristics", use it or loose it, is meant, the blacksmith, as his profession, he is instilling numerous characteristics and adaptations he performs as a blacksmith. It is considered a hereditary mechanism which changes his (the blacksmith) physiology acquired over his life. (Example: muscle enlarged through use) All of those characteristics and adaptations from the blacksmith is transmitted through his offspring. Therefore, the offspring (the son) will be an equivalent and fully strengthened in his father's profession. Also it can relate with the "theory of adaptation". 3. As discussed in class, the blacksmith’s son often has large muscles even before he has taken up his father’s profession. Explain this phenomenon in terms of modern genetic ideas of inheritance. The study of continuous traits (such as height, weight, or in this case musculature) is called quantitative genetics. The combined effect of many underlying genes results in a continuous distribution of phenotypic values over generations. Regardless of the blacksmith's profession, when his genome was passed to his offspring it resulted in offspring with a similar muscular phenotype . 4. Contrast the teleological model of the evolution of humans with the Darwinian model. \ Aristotle was the first to present the teleological model of evolution. This evolutionary idea was based on
