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

Suppose you have four species of lizard and you are interested in how leg length will change in a single generation of evolution under directional selection. Given the following parameters, which lizard do you predict will change the most in one generation? Species A: Heritability: 0.5, selection differential: 1.2 Species B: Heritability: 0.4, selection differential: -1.9 Species C: Heritability: 0.9, selection differential: -0.67 Species D: Heritability: 0.1, selection differential 3.2 Species A Species B Species C Species D

Which of the following statements about the studies on Darwin's finches conducted by Rosemary Grant and Peter Grant since the 1970s is correct?     -For the trait of beak depth, there are clear differences among individuals on the island Daphne Major.     -After comparing measurements of beak depth between parents and offspring across many families, they found that similarity in beak depth is mainly due to genetic inheritance.     -After the 1977 drought, it was found that the average beak depth of the population has increased when compared to the population average before the drought.     -The study of Darwinâ s finches is often used as an example of natural selection in the field.     -All of the above
