Background information In this lab, you will test the hypothesis that the evolution of skull shape within the human lineage took place largely by changing the timing of events in development from a chimpanzee-like ancestor. The change in shape during development (that is, allometry) is a source of heritable variation that can lead to adaptive evolution. In this lab, we’re focusing on how morphology (the shape of an organism) changes through time instead of focusing on how genes change through time. However, these two biological disciplines are united in the study of evolutionary development, or “evo-devo” for short (Carroll 2005). Growth from fertilized egg (zygote) to adult involves a host of complex interactions among genes, molecules, and tissues. Subtle alterations in the timing of gene expression, especially for regulatory genes, can have far-reaching consequences that result in different adult morphology (Carroll 2005).

1. Read the of the above information, and then paraphrase the primary hypothesis you will test in this lab. Next, represent this hypothesis as a schematic (concept map), by drawing what you think the ancestral skull looked like and how the shape of the skull evolved in descendent species.

You will need to read through the lab procedure and background information to solve this question. Need help? See a TA or your instructor in office hours. CaCrO4 is a slightly soluble solid. In the lab, you find that addition of 357.73 µL of 1 M H2CrO4 to 7.924 mL of 0.3 M Ca(NO3)2 results in formation of a persistent precipitate. Addition of water (1.878 mL) just dissolves the precipitate. What is the experimental value of Ksp for CaCrO4 according...

You and your hypothetical lab partner each develop an experimental plan to test this hypothesis. The two experimental plans are presented below. Evaluate each plan for its pros and cons in the experimental design using the bullet points below. Both experimental plans have some good elements and areas that could be improved. Experiment A) Mature 2 inch sections (sprigs) of Elodea will be used to measure oxygen production under different light conditions. 5 sprigs will be tested. One will be...

Were Lamarck's ideas scientific? How so? How might you test his hypothesis for evolution?

you will propose a hypothesis test that will test a claim that is of interest to you in the business world. Then describe how you would gather a representative sample to test that claim. 1. state the claim you wish to investigate in your own words. 2. write a null and alternative hypothesis. 3. describe how you will gather a representative sample to test your claim. 4. state the type of test you would use for example, TTest,1PropZTest, etc.

How did the clash of personalities shape the evolution of radio and television? Did you find this surprising for two 20th-century inventions, because we tend to assume that recent inventions are largely the product of impersonal corporations? How were mechanical and electronic televisions similar? How were they different? Could mechanical televisions be made to work?Why was it that, even from the 1950s, people complained that television programs were bland and predictable?

Evolution Question. An old alternative hypothesis for the evolution of infanticide was that parents killed offspring (including their own) when food was short for the good of the group. On the basis of a modern view of adaptation, why is this not a good explanation for the evolution of infanticide?
