Which statement correctly describes the relationship between evolution and natural selection?

What do we mean when we say that populations of chimpanzees have five times as much variation as populations of humans?

Which process results in new alleles?

  The tree above shows five shapes that represent five different species. Each species has two traits: a color and either pointy or rounded edges.   In case it’s difficult to see the traits by looking at the shapes, here are the species’ traits: A: yellow and round. B: orange and round. C: orange and pointy. D: blue and round. E: blue and pointy.   Question 1: Species B and C are the only species that have the orange color trait. Based on your best hypothesis about where on the tree color traits evolved on this tree, is the orange color of species B and species C homologous or analogous?     Question 2: Species C and E have pointy edges, while species A, B, and D have rounded edges. Based on your best hypothesis about where on the tree pointy edges evolved, are the pointy edges of species C and species E homologous or analogous?

This question is to be sure you are here in class with us taking the exam. Sending this answer to anyone else is a violation of academic integrity (it is cheating). If you are taking this at an approved DRC proctored location you can leave this question blank (or take a guess). What is your lecture TA’s favorite animal? Look on the screen for the answer and correct spelling

While sitting outside looking at a tree, you notice that all of the caterpillars are on the bottom of the leaves and not on the top. This is most closely associated with which step in the scientific method?

A scientist wants to study bird predation of peppered moths. In a natural environment, they put light moths and dark moths on the trunks of trees and observe the moths for 30 minutes. The scientist records if each moth was eaten.  What was the independent variable in this experiment?

Which pair of species is most closely related: Lily and Sunflower or Lily and Tulip?

If a group of rabbits had a high mutation rate and frequently had new rabbits migrate into their group, what would happen to the amount of genetic variation in this rabbit population over time?
