Fitness - the genetic contribution of an individual to the next generation's gene pool relative to the average for the population, usually measured by the number of offspring or close kin that survive to reproductive age. Memorize the four postulates of natural selection. - 1. Individuals vary their traits 2. Some of the variation is heritable and is passed to offspring 3. More offspring are produced than survive to reproduce 4. Survival and reproduction are non-random; those with favorab...

Know the functions of the mammalian respiratory system - to supply oxygen to the cells which they need to perform cellular respiration and to rid the body of CO2 Recall the reason for 'death-zone' - people who are at a certain elevation and above for more than 48 hours get insufficient oxygen Describe the hypothesized reasons for the decline in O2 during the late Permian - Land masses form super-continent which led to a dryer climate and a reduction in photosynthesis which led to the red...
