Evolution Basics
Which of the following things are likely to cause evolution in a population? Try to keep all causes of evolution in mind.
The thickness in fur coat for particular small mammal is determined by the average temperature in its environment. Over time, the environment gets warmer.
A mutation introduces a new wing color in a group of butterflies.
A flood washes away 3/4 of a population of ground squirrels.
Individuals migrate between 2 populations that have the same gene pool.
Within a lizard population, there is genetic variation in the length of the tail. The neighborhood cats chase the lizaards, and have an easier time catching the ones with long
tails.
1) In one paragraph, explain in your opinion, Why do you think the Theory of Evolution is so controversial?
2) In one paragraph, explain in your opinion, discuss your own ideas and also those that you can find by researching online.
Thinking about Natural Selection and Adaption, what if instead the predators were 4 different spoons: ¼ teaspoon, 1 teaspoon, 1 tablespoon, and 1 large serving spoon? Then what if each time beans (the prey) were captured, they had to be immediately emptied into a narrow-necked jar (with an opening about the size of 1 teaspoon)? What do you think the outcome of the experiment might be in this new situation? (Which “predator” will be the most successful, which the next most, etc. down to the least successful, and why?) Be sure to explain your reasoning

Figure 18-18 Differences in DNA nucleotide sequences as evidence of evolutionary relationships Comparing the same gene in different organisms provides a window into evolution. Here the differences in the non-protein-coding region of the -globin gene are compared between humans and other primates.
