Each example must be different from the ones taught in lecture and lab ppt.(Steps to 1 question) 1.Explain the difference between the popular and scientific use of the word 'theory.' What is the relationship between a 'fact' and a 'theory' according to Gould 2.List and explain the three reasons that Gould and other scientists can feel 'confident' that evolution occurred. 3.How does Gould feel about Scientific Creationists, and what does he suggest be done by scientists? What do you think about his perspective? 4. there are six big events in human evolution. Which of these do you feel is the most significant and why? 5.

- Remember that understanding is explanations more than facts. Definitions of phenotype, genotype, allele, gene, microevolution, macroevolution Know that in humans, most of the genetic variation is observed within populations, and know why that is. Know the 4 processes of evolution (3 neutral + natural selection) Know that evolution isn't progressive and doesn't necessarily lead to more complexity Know that evolution can lead to traits that decrease survival (ex: sexual selection) Know that quantitative traits are generally influenced by (i) many genes, each having a small effect on the trait value; and (ii) the environment What is F1 like when you cross 2 homozygotic lines of peas of different colors? What is F2 like when you cross F1 individuals (remember what 9:3:3:1 is about) Know what genetic dominance is about Definitions of chromosome, nucleus, mitosis, meiosis, crossing over How many chromosomes in humans? How many pairs of chromosomes? Know and apply Hardy-Weinberg's equation…2020 Online Discussion B. Darwin's Theory Warm-Up Active Developing the Theory of Evolution WARM-UP What was Charles Darwin's contribution to the theory of evolution? O Charles Darwin was the first to express the belief that all living things are related. Charles Darwin believed that organisms had a goal to adapt and did so through the inheritance of acquired traits. Charles Darwin introduced the idea that organisms better adapted to their environment would tend to survive, reproduce, and increase in number. Charles Darwin developed the theory of population growth. DONE O Intro Activity DII 96 2, or goBackground: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blank
- C. Adaptation and Genetic Variation. The picture below represents four different species of finch. Study the picture and answer the questions that follow. 2 3 1. The finches have different beaks based on what they eat. Which do you think eats seeds? 2. Which do you think eats insects? 3. Which do you think eats leaves?. 4. Which do you think eats fruits? 5. Darwin theorized that all four of these finches evolved from one ancestor. Why do you think their beaks evolved?Directions: Write ADAPT if the statement is under the principle of Jean Baptiste de Lamarck and EVOLVE if the statement is under the principle of Charles Darwin. 1. Species may experience extinction if they are not fitted to live in their environment. 2. Species, which become extinct, just experienced evolution to fit in their environment. 3. Once a trait is developed due to adaptation in environment, it may be passed to succeeding oripnisms. 4. Habitual actions with a specific body part may lead to its changes. 5. Body parts that are of no use but still present in an organism's body are evidence for its ancestor species. 6. Animals with the same body part may have modifications depending on its physical requir. ements. 7. Changes happen in an organism for a long and uniform process. 8. A body part that is no longer used by an organism may lag from its development. 9. Birds grew web-like structure on their feet to be able to feed on the surface of water. 10. Ancestral…Activity 4.
