Overview

A super continent, Pangaea, began to break apart into the modern continents about 260 million years ago, causing the isolation (and separate evolution) of various groups of organisms from each other. Since this event, the living species inhabiting these separate continents have progressively changed. Organisms have learned to adapt through hiding, camouflaging and mimicking other organisms’ efforts to outfox potential predators seeking their next meal. Many of these changes can be attributed to the concept of evolution which includes physical as well as behavioral changes.

Using video and Internet resources, students will be able to gain a clearer understanding of evolution by examining its effects as evidenced in amazing adaptations and unusual biodiversity in some of the most remote areas of this world. More importantly, students will learn the secrets of how these organisms find ways to survive. In addition, students will create digital video projects of their own to demonstrate their knowledge, illustrating common evolution in their own world.

Major corporate support is provided by Canon U.S.A., Inc. and Ford.

Learning Activities

Students will be able to:
  • Define evolution and its relative impact on the perpetuation of species;
  • State various ways in which organisms adapt in order to survive;
  • Discover new forms of biodiversity found in various remote regions of the world; Clearly define such terms as Pangaea, mimicry, adaptations, natural and sexual
  • selection, analogous structures, convergent evolution and speciation;
  • Utilize video, Internet and print resources to research information;
  • Work collaboratively to produce a presentation, video or other product.

Various marine organisms hide through unique blending with their underwater environments.

Bioluminescence

Using light sources within their bodies, fishes manage to find shelter and food in the darkest parts of the ocean.

Defenses
