Document Summary

Next friday during regular class time --- in regular classroom --- can go ask him questions!! Designed to show us what happens when we exercise under different environmental conditions: with regards to sweat rate, body composition, weight loss etc 1st video: sweat rate is based on body weight losses. Individual is weighed with his water bottle (will get the weight of his body and how much water he had to drink) pre-weight: now he will exercise in an environmental chamber. race on the bike that corresponds to a road race outside. chamber controls temperature and humidity: under the first condition. Low temperature and low humidity: under the second condition. high temperature and high humidity: now he will be weighed post-exercise. 2nd video: now he s in the chamber under hot and humid conditions, gets more water because we anticipate that he will sweat more. Sweat rate exercise performance experiment slide 22, 23.

two populations of different endothermic species evolved in different enviroments. One species evolved in an environment of variable seasonal temperatures: high summer temperatures and low winter temperatures. the other species evolved in a relatively constant 20 degrees Celsius environment. Supposed both populations were subjected to a new environmental temperature. Which species would be better adapted to the new conditions?

In mutation accumulation experiments on Caenorhabditis elegans, deleterious mutations were observed to accumulate at a slow but steady rate when the populations were grown in a benign environment, with optimal temperature and humidity, minimal crowding of individuals, abundant food, and no predators or parasites. Control lines grown under normal conditions did not accumulate mutations at the same rate. After 240 generations, experimental lines that had accumulated substantial mutations were removed from the benign environment and these lines were propagated. Explain the results once the recovery lines were established, and how this experiment demonstrates the significance of natural selection in the evolutionary process.
