Over time trees get taller and it is helpful for giraffes to have longer necks that Name and briefly explain two hypotheses that have been proposed to understand selection for stronger display and corresponding preference in the other sex. To see how it works, imagine a population of beetles: There is variation in traits. The students are asked to perform various tasks as quickly as possible with simple materials. All the materials help reinforce "change over time" and evolution through natural selection.
