PRESENT DAY Habitat and Geographic Location The Orcas can be found in all the world’s oceans. Their location ranges from the equator to both polar regions. Orcas inhabit deep ocean waters and coastal shallows. The northern and southern ranges are limited by pack ice. The orca stays in one area all year‚ and travels within its home range for prey. Some populations migrate toward the equator in the winter and back toward the poles in the summer. The orcas adapt well to any climate‚ however‚ coastal

THE CONCEPT OF SPECIES What are species? Species are the basic taxonomic units of biological classification. This grouping of organisms of "like kind" into discrete and stable units has been traced at least from the time of Plato and Aristotle. The term derives from the Latin "specere" (to look at‚ to behold)‚ with the meaning of "kind‚“ "quality‚" "appearance‚" "shape‚" or "a peculiar sort.“ In the past‚ species were classified according to their shape. Carl Linnaeus (1707-1778)‚ the

Mississippi’s Microbe In developing a microbe to represent Mississippi best‚ one must ponder the item most important to many Mississippians—food. For some the food of choice may be a juicy steak; but for others‚ the favorite part of any dinner is dessert. Those in search of the best desserts of every state choose to come to Mississippi for the “Mississippi Mud Pie‚” also known as the “Muddy Mississippi Cake” (Penn; “Mississippi”). The “Mississippi Mud Pie” is a tasty treat composed of three tiers:

The Facts of Evolution 1. What is the point Shermer is trying to make in this article? Shermer’s point is that evolution is a historical science and it did in fact happen and there is a lot of evidence to support that it did. 2. What was Darwin’s contribution to our understanding of coral reefs? Our understanding of coral reefs is now that there aren’t different kinds of coral reefs but rather all coral reefs are in different stages of development. 3. Who was Darwin’s “one long argument” with?
