Ecology: Happy vs Sad Bears


Natural selection is the process in which organisms that are best adapted to a set of environmental conditions survive long enough to reproduce, also known as "survival of the fittest". Today Keytesville Ecology class used Teddy Grahams to demonstrate how natural selection happens in nature over generations. On close inspection one will notice that the crackers come in two phenotypes; happy and sad bears. Only happy bears where eaten, demonstrating how natural selection can affect the frequency of a single trait in a population through successive generations. Afterwards, students were allowed to enjoy a Teddy Bear snack as well!
