Dinosaur Biology: The Process of Evolution
Darwin's Theory of Evolution by Natural Selection
Darwin used an elegant biological argument to accomplish two important tasks. First, to
document that evolution has taken place and second to provide a mechanism for
evolutionary change. This laboratory will be a virtual mini museum of Darwin's
Evolution and the evidence for his views. First, you should watch the narrated
introduction to evolution to prepare to visit the exhibits. You should visit each of the
“exhibits” read the appropriate caption and answer the following questions. The various
exhibits can be found at http://faculty.msj.edu/kritskg/evolab
Population potential
1. Do humans illustrate the population potential?
*A. Yes

A. famine

C. war
*D. all of the above
Population variation
3. How do the beetles lower spots change?
A. The spots disappear
B. The spots merge making the wings totally black

D. The spots separate into many spots
Struggle for existence
4. The snails that survive to reproduce are _______.
A. those that are a different color from the ground where the snails live.

Biogeography
11. Which one (species 1 or species 2) is the most variable?
*A. species 1
B. species 2
12. Based on Darwin's views of variation and distribution, which distribution, species A
or species B, do you think is the distribution for species 1 and which is the distribution
for that of species 2?
2
*A. The larger distribution belongs to species 1
B. The smaller distribution belongs to species 1
Succession of Types
13. What would be the benefit of these scutes or the armor covering?
