Document Summary

Positive correlation vs negative correlation vs no correlation. More space = less competition = more resources. Islands closer to a continent have higher immigration rates than farther islands. Species diversity in habitats like caves, lakes, mountaintops show patterns similar to oceanic island diversity patterns. Pleiotropy: one gene has an effect on multiple traits. 4 mechanisms of evolutionary change: natural selection, gene flow (migration, mutation, genetic drift. Usually plants or insects: ex: thorns on roses. Mosses dominant phase of life is haploid. Flowering plants dominant phase of life is diploid.
