6. Suppose that an island fits the dynamics of the island biogeographic model. The colonization of an island (C) is a function of the number of species (S) on the island: C = e raised to the –0.1S. The extinction of species already on the island (X) is also a function of S: X = (e raised to the 0.001S) – 1.

5. Graph the relationship of C as a function of S, and X as a function of S, for S between 5 and 100 at intervals of five (S = 5, 10, 15...).

CAN SOMEONE HELP ME WITH THIS QUESTIONS?? THANK YOU

If all organisms originated in their present forms during a single event, Darwin wondered, why was there a distinctive clustering of similar organisms in different regions of the world? Why were all types of organisms not randomly distributed?


Why would living and fossilized organisms that looked similar be found within the same region?


Why did the Galápagos species so closely resemble organisms on the adjacent South American coastline?


Why was there such a diversity of species in such a small area? Could these species have been
modified from an ancestral form that arrived on the Galápagos Islands shortly after the islands
were formed?
