Concept explainers
In 1995, the Alabama School Board, after reviewing high school biology texts, voted to require that this disclaimer be posted on the inside front cover of the approved book (National Public Radio 1995):
This textbook discussed evolution, a controversial theory some scientists present as a scientific explanation for the origin of living things, such as plants, animals, and humans. No one was present when life first appeared on Earth; therefore, any statement about life’s origins should be considered as theory, not fact.
Do you accept the last sentence in this statement? Does the insert’s point of view pertain to other scientific theories, such as the cell theory, the atomic theory, the theory of plate tectonics, and the germ theory of disease?

Evolutionary Analysis (5th Edition)
- Usie the following textbook link to answer the question: (https://pressbooks.calstate.edu/explorationsbioanth2/chapter/2/) 1) In one paragraph, explain in your opinion, Why do you think the Theory of Evolution is so controversial? 2) In one paragraph, explain in your opinion, discuss your own ideas and also those presented in the 3 trials discussed in the textbook reading linkarrow_forwardIn this activity, you will be creating a concept table of the theories of evolution. You will be given the names of nine scientists that have had an impact on what we currently believe about evolution and you will explore their ideas and theories. You will complete a table that follows the theories of evolution through time. Your table will include the following scientists: • Linnaeus • Hutton • Lamarck • Malthus • Lyell • Darwin . Wallace The table will include the name of the scientist, approximate dates, explanations of the concepts they explored, and the general theory or topic they are credited with. Below is the table you will fill in, with an example of what one part of the table might look like. Use the example to guide you with how much detail is required and how in-depth your responses must be. Be sure to include the following key terms somewhere in vour table. Key Terms: gradualism, catastrophism, taxonomy, use & disuse theory, paleontology, binomial nomenclature, evolution,…arrow_forwardScientists Stanley Miller and Harold Urey set up an experiment modeling the environmental conditions thought to exist during the early stages of Earth's formation. The setup of Miller and Urey's experiment is shown below. Which conclusion about the origin of life could be drawn from the potential results of this experiment? Life assembled from chemical building blocks. Life began when water vapor became electrified. Life evolved from the DNA of simple unicellular organisms. Life began when salt water caused a mutation in an ancient virus.arrow_forward
- Address (don’t just say “true” or “false”) the following myths about evolution. Limit your answers to 1-2 sentences each: a. Evolution tells us how life began b. Evolution says animals do things for the good of their species. c. If evolution were true, they would call it a fact, not a theory.arrow_forward"Evolution can work toward an eventual improvement." Please correct this statement in a meaningful wayarrow_forwardDiscuss the validity of the statement “Evolution is an equal opportunity biological phenomenon”. Do you agree or disagree? Give examples that support or refute this statement.arrow_forward
- In this discussion, you will discuss the social issues related to evolutionary theory and its common misconceptions. One of the major social issues is how evolutionary theory should be taught. Some people think that evolution should be presented as one of many theories, including creationism. Other people think that evolution should be presented as the only explanation for the change in Earth’s species over time. What do you think? Use your scientific knowledge to support your position.arrow_forwardImperial China during the Ming dynasty (1368-1644 CE) could conceivably have started the Scientific Revolution before Europe; its failure to do so might have resulted (at least in part) from each of the following factors except: foreign trade was dominated by the Imperial Navy, with no profit motive for merchants European sailing vessels of that time were much smaller than Chinese treasure ships Chinese religion was polytheistic, while the central government at that time was strong military expenditures were diverted from ship-building to land-based armed forces Chinese colleges were independently-chartered, not under Imperial control like Europearrow_forwardCreate an informative essay showcasing the importance of evolution in our lives. With the changes in the structure of living organisms like plants and animals, how did these changes help the community of living organisms? How will the evidences found by several scientists be of help to us and to other organisms as well?arrow_forward
- Select the true statements from the following regarding the evolutionary theories that are thought to have combined to give rise to life on earth. Reproduction is required for both chemical and biological evolution. Both chemical and biological evolution are defined by change over time. Purpose of Miller-Urey experiment was to answer the question: can chemistry give rise to complex molecules required for life? The Miller-Urey experiment showed that chemistry can give rise to the molecules required for evolution of life.arrow_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_forwardDespite being elegant and compelling, the theory of evolution by natural selection proposed by Darwin and Wallace was ignored by most of the scientific community of their time. Please give one reason why their theory was not readily accepted.arrow_forward
