Evolution by Natural Selection
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.
Love as an Evolutionary Adaptation

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

At first thought, love appears to be too complex and ambiguous to define
in a scientific manner. As Professor Le
mentioned, social scientists do not attempt to operationalize complex emotions
like love in their entirety. For example, by demonstrating love-directed
behavior in one instance is a study able to be generalized to other
Birth Order--Evolution at its Best?

Darwinian evolution explains the small differences within the same type of individuals and how this variation creates competition for the best to survive and pass on the best genes (1). Now, 170 years later, Darwinian evolution still prevails, even in the household of every family.
It is no surprise to see siblings in argument, especially because of clashing personalities. But why is the fighting so common? Is it only due to differences in personalities? Or could this fight actually be Darwinian evolution in the works? Could this fight be a form of competition to seek superiority?
