, Adaptation A trait that helps an organism survive and reproduce
Requires scientific experimentation to determine if
adaptive trait
Agents of Selection (Survival) Find food
Avoid predators/parasites
Compete/cooperate with others
Protection from elements
Agents of Selection (Reproduction) Find mate
Surplus energy to make offspring
Care for offspring
Defend mating territory
Tests to determine if trait confers 1. Observational study/Natural experiment
increased fitness 2. Controlled experiment
3. Comparative methods
4. Computer simulation (mostly ignore)
adaptation vs acclimation Traits that allow individuals to survive and reproduce
better in certain environments than individuals
lacking those traits. Acclimatization refers to
phenotypic changes in response to short-term
changes in the environment.
Adaptations to avoid mountain Requires survival w/ low hemoglobin levels
sickness (Observational Study)
Tibetans--inhale more with each breath
Peruvians--increased oxygen-carrying capacity in
Hgb/+RBC
MS Agent of selection Tibetan women w/ 2 alleles for high blood-oxygen
content had more surviving children
Fly experiment (Controlled Flies with wings and behavior avoided predation.
Experiment) One or the other wasn't enough to avoid death.
