Population Pyramids 8/31
The population of Turlock seems to be increasing with more young adults and kids.
The population of Seattle is stagnating because of all the young adults with little elderly people.

Sonoma's population is very fluctuating with more elderly women than elderly men. There are also more elderly in general.
Humboldt has a good amount of young adults as well as elderly so their population is increasing.
Palo Alto has more middle-aged people with small kids so their population is slightly declining.
Merced's population is greatly increasing with many kids and young adults.
Petaluma is slightly increasing to neutral with many middle-aged people and slightly less young adults and kids.
9/15 Data Maps
The southern states of the U.S. continue to remain in extremely high temperatures, while the northern states tend to be much cooler on average.
States close to the east, most prominently east Texas and Florida, receive much more rainfall than states in the west. This is due to more tropical storms and hurricanes in the east.
Half of the U.S. had a chance of severe weather with states in the mid-west being in the most danger and states near the coast of the east in danger as well.
States in the north-west were drastically warmer than usual such as states like Washington and Oregon. Compared to the states over in the east which were cooler than normal. States in the mid were for the most part unaffected.
California is almost out of the drought, but from this map it would seem that the drought has moved up north and in some parts of the mid-west.

Post-lab Questions
1. Of the two parking lots, the student parking lot was the most diverse. Based on observations from our pre-lab, we predicted that the student parking lot would be more diverse because kids don't have much say in what their first car is.
2.Fords were the most abundant in the adult parking lot, this may be due to the fact that adults could have more say in the car they drive so they can choose to drive a brand that's a little more expensive than Toyotas. Toyotas were the most abundant in the student parking lot, most likely because Toyotas are affordable for a first car.
3. The minimum comes from the adult parking lot at 1.7 and the maximum comes from the student parking lot at 1.8.

10/31 Wooly Worms Conclusion
A. The degrees of freedom used in this exercise was 6
C. The calculated chi-square value is 40.06.
D. The results indicate that chance alone did not cause the unequal number of captured wooly worm phenotypes. Some worms had a better chance of blending into the environment due to their appearance leaving the others to be captured more frequently.
E. The green worms like stringbean, olive garden, and shrek were subjected to a positive selection because their green color gave them the edge in blending in. On the other hand, Stripey, eyelash, burt, and shaggy were at a huge disadvantage because of their bright colors giving them a negative selection.
F. These results indicate that over time, the wooly worm population will become less diverse with the green colors becoming more common due to there being more with a positive selection to reproduce.
G. Characteristics like these could give worms with a bright color a slight advantage but it could also give them a disadvantage.
H. If the environment remained unchanged, the wooly worms with bright colors would soon go extinct leaving only the worms with a positive selection to reproduce. In ten years, the community would just be full of worms with a green color with little to no worms with bright colors. Over more time, those with a negative color could also evolve to better adapt.
