- What is meant by biological evolution?arrow_forwardHow do advantageous traits lead to evolution? Put the steps in the proper order. advantageous trait → survival of the fittest → natural selection → differential reproduction → evolution advantageous trait → survival of the fittest→ differential reproduction → natural selection → evolution advantageous trait → differential reproduction → survival of the fittest → natural selection → evolution advantageous trait → natural selection → survival of the fittest → differential reproduction → evolutionarrow_forwardWhat are the essential characteristics of science? Describe how evolu-tionary studies fit these characteristics whereas “scientific creation-ism” or “intelligent-design theory” does not.arrow_forward
- What is fitness? To what degree does fitness dependon the environment in which organisms live?arrow_forwardIn what sense is natural selection more an editing process than a creative process?arrow_forwardOutline the levels of biological organization. What is the difference between the reductionist approach to biology and the systems approach? What are the strengths and weaknesses of each?arrow_forward
- 150 patients with Crohn’s disease are given an experimental treatment in which they all drink “cocktails” containing thousands of pinworm eggs. Within one week, 72% of the patients report a reduction in their abdominal pain. Fill in the following table. Is there a control treatment (and, if so, what is it)? Is there any accounting for individual variation? Is there repetition in the experiment? What, if any, confounding variables are not addressed in the experiment? Can we say with some confidence that ingesting pinworm eggs is an effective treatment for the symptoms of Crohn’s disease?arrow_forwardExplain the relationship between adaptation and theprocess of biological evolution.arrow_forwardWhat is the relationship of evolution and human behavior?arrow_forward
