Concept explainers
Advocates of “scientific creationism” and “intelligent design” lobby school districts for such things as a ban on teaching evolution, equal time in science classes to teach alternative versions of the origin and history of life, or disclaimers in textbooks stating that evolution is “just a theory.” They argue that it is only fair to let students evaluate both evolution and the idea that all species were created by God as the Bible relates or that, because organisms are so complex and well adapted, they must have been created by an intelligent designer. Do you think that alternative views of evolution should be taught in science courses? Why or why not?

- Can you please help me with this question The theory of evolution was controversial when it was first proposed in 1859, yet within 20 years virtually every working biologist had accepted evolution as the explanation for the diversity of life. Explain in at least 50 words why.arrow_forwardThe theory of evolution was controversial when it was first proposed in 1859, yet within 20 years virtually every working biologist had accepted evolution as the explanation for the diversity of life. Explain in at least 50 words why.arrow_forwardCharles Darwin established a theory of evolution based on variation, competition, and survival in the living world by studying careful observations made on a sailing trip around the world. Darwin put forth two main concepts: evolution and natural selection.- Organize your thoughts about Darwin’s ideas of evolution by filling out the concept map below.arrow_forward
- Hello! I have a discussion tommorow with my classmates, and the prompt says like this: Discuss whether changes to an organism's physical environment are likely to result in evolutionary change. Use examples to support your reasoning. Second, using at least two examples, explain how the process of evolution is revealed by the imperfections of living organisms.arrow_forwardMisconceptions about Evolution Generate a separate list of evidence, common misconceptions, and criticisms related to the theory of evolution.arrow_forwardThe concepts of natural selection and evolution are central to how most biologists understand and interpret the world, and yet the theory of evolution is contrary to the beliefs of many religious groups. Why do you think this theory is so important to science and so strongly opposed by others? What evidence would be required to convince opponents of evolution?arrow_forward
- Discuss briefly the origin of life according to the theories listed below and justify which theory is better to test by scientific method. Your justification should include formulation of hypothesis for each theory Theory of Special Creation Theory of Spontaneous Generation Theory of Catastrophism Cosmozoic Theory (Theory of Panspermia): Theory of Chemical Evolutionarrow_forwardIntelligent design is the theory that life is too complex to have evolved randomly. The eye is often cited as an example, arguing that its complexity argues for the presence of a creator guiding its development. What use is half an eye or a partial wing? It is a popular idea because it does not deny the observable fact of evolution, while leaving room for the presence of God. Is intelligent design a viable scientific theory? Why or why not?arrow_forwardIn 1973, biologist Theodosius Dobzhansky wrote an essay titled “Nothing in Biology Makes Sense Except in the Light of Evolution.” Why is evolution so important for understanding biology? Explain your answer in 1–2 sentences.arrow_forward
- Put this in a 400-word paragraph The Development of Evolutionary Theory, Lecture 2 This 17th-century map shows the Earth at the center of the solar system. • Ideas generated out of the Scientific Revolution challenged such long-standing beliefs. • Aristotle argued that the sun and the planets revolved around the earth. George-Louis Leclerc, Comte de Buffon (1707-1788), recognized the dynamic relationship between the external environment and living forms. • Although he never discussed the diversification of life over time, he recognized that different regions have different plants and animals and that alterations of the external environment (such as climate) were agents of change. • Some scientists today (Ernst Mayr) credit Leclerc as the “father of evolutionism Jean-Baptiste Lamarck developed a theory to explain the evolutionary process, known as the inheritance of acquired characteristics. • An example is the giraffe: having stripped the leaves from the lower branches of a tree,…arrow_forwardRegardless, many people have a problem with the idea of evolution. Why? To complete it, answer some of the following questions: Why is evolution so controversial? Does understanding it better make it less controversial? What were you taught to think/believe about evolution? Why?arrow_forwardFind two cases in the media (internet, TV, etc.) of a person (organization, etc.) attempting to describe and example of the process of Darwinian evolution but is incorrectly describing the evolution process using a Lamarckian approach to evolution. Give the following information for both cases: Source (Where you found it) In what ways are they mistakenly claiming that the evolutionary process is an example of Darwinian evolution? How do you know that they are really describing evolution through a Lamarckian process, not a Darwinian process?arrow_forward
