Chapter 20, Problem 14TYK
Summary Introduction
To review:
Three discoveries or inventions that have changed how humans are affected by natural selection and discuss how each discovery influences survival or reproduction in our species.
Introduction:
Humans have evolved through generations and there were many examples, which support that human evolution is due to natural selection. But it was later found out that these traits are results of changes in genetic makeup of the organisms.

- 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_forwardExplain how understanding evolution is important to medicine, agriculture, and maintaining the diversity of Organismsarrow_forwardDiscuss the process of evolution through natural selection. What could happen to the ecosystem and animals in ten, one hundred, or one thousand years? Is it feasible for them to continue evolving or do they eventually become extinct? Explain your answer concisely.arrow_forward
- Charles 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_forwardExplain Natural Selection using the terms evolution, fitness, adaptation, heritable train, and mutationarrow_forwardProvide a scientific example of evolution and/or natural selection. You can use human and/or animal examples. Describe how the animal/species developed an advantage over time or what the evolutionary process was.arrow_forward
- Explain the relationship between adaptation and theprocess of biological evolution.arrow_forwardDo you think the human race is continuing to evolve in a Darwinian, genetic sense? Are the genes of our species changing? Do not just write "yes" or "no," but explain why you think so. In addition, include in your explanation of how the mechanisms of evolution, such as natural selection, would be at play.arrow_forwardWhy is it important to study evolution? Explain in three paragraphs.arrow_forward
- ln three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for this claim, and be sure to explain how an organism shows the four parts of the process of natural selection. You may use any organism with the exception of bacteria and antibiotic resistance.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_forwardReview darwin's theory of natural selection. Write a 1-2 paragraph reflection explaining a) what you learn from the evidence of revolution and b.) The connections you made with what you learn about darwin's theory of natural selection and how meet mutations play an important role in the natural selection.arrow_forward
