- 1. Wood duck is one of the most recognizable birds in the United States. In the late winter season, the males attract the females with their call and colorful markings. The female wood ducks chose their partner based on their attractiveness. They then pair up and begin breeding in the early spring. What mechanism of evolution is described in the given situation? a. natural selection b. genetic drift c. non-random mating d. genetic flow 2. Which of these factors DO NOT produce an adaptive evolutionary change in a given environment? a. natural selection b. none of them c. mutation d. genetic drift1. THE PROCESS BY WHICH ORGANISMS CHANGE OVER TIME IS KNOWN AS 2. THE PROCESS WHEREBY ORGANISMS THAT ARE BETTER ADAPTED TO THEIR ENVIRONMENT TEND TO SURVIVE AND PRODUCE MORE OFFSPRING IS KNOWN AS 3. WHO DEVELOPED THE THEORY OF USE AND DISUSE? 4. WHICH THEORISTS SUGGESTED THAT ORGANISMS CAN "ACQUIRE" THE TRAITS NEEDED TO SURVIVE DURING A LIFE TIME? 5.

Explain why the pharyngeal slit becomes the Eustachian tube in humans and a gill in fish.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.
