Long description of the image in Figure 3 of the Macroevolution FAQ:

The image on the left is labled "External factors (climate, geology, ecology)" with, working from bottom to the top, letters A through G whose meanings are explained after the image. These letters have arrows that point to the the right side of the image. The right side is labeled "Macroevolution and Microevolution" The bottom half is Microevolution (within species). This divided into the Organism level which is subdivided into Genetics and development and the Interactions between organism which is subdivided into populations and Migration/dispersal. The top half divided, starting from the middle and working up, Independent evolution (vicariance), Historical Contraints/Developmental contraints, and species selection.
