One possible theme of The Call of the Wild could be that only the strongest survive. Explain how this relates to Darwin's theory of natural selection and the survival of the fittest. Do you agree or disagree with this idea? Is there one aspect with which you agree but another with which you do not?

In your own words, how does Inheritance support natural selection? Use at least 1 example from the Beaks of Finches lab in your answer.

Which of the following is NOT one of Darwin's postulates?   Individuals in a population will have different versions of phenotypic traits   Individuals in a population will vary in how successful they are with respect to survival and reproduction   Some phenotypic traits can be passed from parent to offspring   Individuals change in response to the environment, and pass those changes on to the next generation

can you describe an example of natural selection? your example can be real or imaginary. just be sure to tell us whether it is true or not!

Is natural selection only a negative process that removes nonadapted and lesser adapted forms? Explain your answer.

Natural selection can act on both ________, which is the probability of survival, and ________, which is the number of offspring produced. a: epistasis; epigenetics b: directional selection, frequency dependent selection c: livelihood; income d: viability; fecundity

Darwin was not the first to propose a mechanism for evolution. Lamarck proposed “acquired inheritance” in which individuals inherit those traits acquired in the lifetime of their parents (e.g., long necks). Compare Lamark’s mechanism to Darwin’s mechanism for evolution (descent with modification). As part of your answer describe how each theory is similar to the other and how each is different? Finally, Lamarck’s theory can be easily shown to be unworkable (e.g., amputees don’t have babies that are amputees meaning babies don’t inherit the acquired trait). What makes Darwin’s theory workable when compared to Lamarck’s unworkable theory.

Darwin believed in Natural Selection as the major explanation for evolution.  Explain how the following organisms’ interactions contribute to this theory. 1. How did organisms Have Heritable Variation help with his theory? 2. How did Organisms Compete for Resources help with his theory?

Look at the last sentence in Chapter 7 from the first edition of the Origin. It’s a remarkable sentence. Describe in your own words what Darwin is saying. Finally, it may not be a logical deduction, but to my imagination it is far more satisfactory to look at such instincts as the young cuckoo ejecting its foster-brothers,-ants making slaves, -the larvae of Ichneumonidae feeding within the live bodies of caterpillars,-not as specially endowed or created instincts, but as small consequences of one general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.
