Document Summary

In a common garden, both males and females from higher elevation populations grew to a larger size: raised young together from different origin elevations. Illustrates that individuals give birth to organisms like themselves, and that individuals differ in heritable ways: potentilla glandulosa (sticky cinquefoil, three common gardens for p. glandulosa experiment in the 1930s, from coastal. California to 1500m in the sierra nevadas: added a layer of complexity, statistics more advanced, ecotypic variation that shows local adaptation in potentilla, null hypothesis no genetic variation. Individuals produce more offspring than the environment can support. Lizard species that use mostly narrow braches have shorter limbs and slighter bodies. Lizard species that use mostly wide branches have longer limbs and stockier bodies. Live for only a few years: short time to maturity, sexually reproduce for a long time, null hypothesis was there would be difference in leg lengths, hypothesis leg morphology is a result of natural selection.
