Thread: Question 1 Post: RE:RE :Question 1 Author: David Schultz Date: Wednesday, April 4, 2007 Status: Published Overall rating: Not rated OK. And similar examples can apply more broadly. On the plains of Australia kangaroos are the dominant herbivores. Many other continents have similar plains and climates but have other organisms as the dominant herbivores. Grade: 5 Thread: Question 1 Post: RE :Question 1 Author: Stephen Byrne Date: Tuesday, April 3, 2007 Status: Published Overall rating: Not rated examples that show that neither the differences or similarities of organisms in variouse geographical areas are wholly accunted for by phyical and environmental factors, can be seen when considering organisms that are endemic, meaning they are found in only one location. An example of an endemic species is the redfin darter, this fish is endemic to the rivers of the Ozark forests. there are many forests throughout the world with similar environmetal and physical factors, but the redfin darter is only found in the Ozark forests. Thread: Question 1 Post: RE:RE :Question 1 Author: David Schultz Date: Monday, April 2, 2007 Status: Published Overall rating: Not rated I don't think Darwin was talking about traits that don't have a genetic basis. I'll give 2 points for this submission. Try to think of a better example. Thread: Question 1 Post: RE :Question 1 Author: Stephen Byrne Date: Monday, April 2, 2007 Status: Published Overall rating: Not rated I would think language would be an example. If one considers a community which lives in the rocky mountains where it is cold and rugged terrain versus a community that lives in Aulstrailia where it is hot and relativly smooth, they both speak the same language and live in almost opposite environments.

Author: David Schultz Status: Published Overall rating: Not rated Give an example that shows that "Neither the similarity or dissimilarity of the inhabitants of various regions can be wholly accounted for by climatal or other physical conditions." Thread: Question 2 Post: RE:RE:Question 2 Author: David Schultz Date: Monday, April 2, 2007 Status: Published Overall rating: Not rated I'm not sure Darwin recognized this, but it is an example. It is a barrier and organisms on either side have diverged. Grade: 5 Thread: Question 2 Post: RE:RE:Question 2 Author: David Schultz Date: Monday, April 2, 2007 Status: Published Overall rating: Not rated This is not an example. It is a general description of the principle. What organisms would allow you to conclude that this is a general principle? Thread: Question 2 Post: RE:Question 2 Author: Jill Breaux Date: Monday, April 2, 2007 Status: Published Overall rating: Not rated Darwin recognized noticeable differences among the marine organisms on each side of the Isthmus of Panama. This led to the idea that the Isthmus, which is the barrier because it is now enclosed by land, was open until the late Pliocence. Thread:
