Feeding of Diarmis Proboscis
Science Scope, v28 n4 p56-58 Jan 2005
The feeding of Diarmis proboscis is an exciting outdoor laboratory activity that demonstrates a single concept of adaptations--cryptic colorations. The students are "transformed" into D. proboscis (no Harry Potter magic needed) in order to learn how adaptations work in the natural world. Prior to beginning this activity, students should have a basic understanding of natural selection. Every species of organism has unique characteristics that help it to survive. In response to the organism?s environment, that species may evolve or change over time. The changes that make the organism better suited to the environment develop through a process called natural selection. Natural selection works like this: Individuals in a population have different characteristics. Those individuals whose characteristics are best suited for their environment tend to survive and produce offspring. Offspring that inherit the characteristics that made their parents successful also live to reproduce.
