In the lab, Evolution by Natural Selection, principles of natural selection are demonstrated by a simulation involving different color pompoms on different color and texture habitats and student feeders equipped with different types of feeding implement. Students learn how different adaptations contribute to differences in survival and reproductive success, which results in changing frequencies of genotypes in the populations.

By its very nature, love is an irrational and capricious emotion. The Merriam-Webster dictionary defines love twelve different ways (thirteen if you count the tennis term), and there have been countless attempts made by poets, musicians, philosophers, and literary figures to distill and define the essence of this powerful emotion.
