17.According to the excerpt from the Descent of Man in Sources of Making of the West… Charles Darwin asserts that observed differences between human races are evidence of multiple places of origin for humanity. Darwin acknowledges that his conclusions “will be denounced by some as highly irreligious” but he dismisses this as a valid argument against his explanation of human origins. Darwin asserts that “the assumed instinctive belief in God” is a valid argument for the existence of such a God. Darwin deliberately insults the Christians in his reading audience to gain traction for his arguments.

Name Date 4. (5:17) Which of the following correctly describes a principle of natural selection? A. Variation in phenotype is what distinguishes one species from another. B. Individual members of a species are only able to pass down favorable traits. C. Populations produce more offspring than the environment can support. D. Only individuals that don't have unfavorable traits are able to reproduce. 5. (5:59) Which of the following is key to Darwin's theory? A. Individuals evolve over their lifetime as their environments change. B. Species evolve over generations as certain individuals reproduce. C. Humans evolve over their lifetime while animals evolve over generations. 6. (10:13) In your own words, explain the difference between directional selection, stabilizing selection, and disruptive selection. 7. (11:24) In your own words, explain how sexual selection also contributes to evolution. 8. (12:21) What is one question you still have about natural selection?
Why was Jean Baptiste Lamarck wrong about the mechanism of evolution? A. Because giraffes haven't evolved in billions of years. B. Because individuals do not pass on any traits that they acquire during their lifetime. C. Because individuals can change their traits during their lifetime and pass on those traits to their offpsring. D. Because he misunderstood the structure of DNA.
How did Darwin support the idea that natural selection can produce evolutionary change? Group of answer choices A. he examined how humans produced domesticated plant and animal breeds B. he just thought it had to be true C. he invented a time machine to go back and check it out for himself D. he observed wild populations to see natural selection in action
A farmer spends much of her time outdoors. As a result, her skin has become very tanned. What would Lamarck predict about her children? What would Darwin predict about her children? Who would be correct, and explain why?
Vhy was natural selection controversial to biologists in Darwin's time? It was a cruel and unfair principle as to why species change. B) It went against the religious beliefs of the time. There was no evidence that descent with modification during Darwin's time. He had no explanation for how advantageous traits were passed from parent to offspring.
Charles Darwin proposed that evolution could be explained by the differential reproductive success of organisms that resulted from their naturally occurring variation. Darwin called this process (a) coevolution (b) convergent evolution (c) natural selection (d) artificial selection (e) homoplasy
What observations that Darwin made on his round-the-world voyage influenced his later thoughts about evolution?
Darwin suggested that evolution takes place by (a) mutation (b) changes in the individuals of a species (c) natural selection (d) interaction of hormones during competition for resources (e) homeostatic responses to each change in the environment
Why are alternative scientific theories to evolution not taught in public school? a. more theories would confuse students b. there are no viable scientific alternatives c. it is against the law d. alternative scientific theories are suppressed by the science establishment
Which of the following is not part of Darwins mechanism of evolution? (a) differential reproductive success (b) variation in a population (c) inheritance of acquired (nongenetic) traits (d) overproduction of offspring (e) struggle for existence
