WebEveryday Connection for AP® Courses. Until recently, these three species of short-tailed pythons, Python curtus, Python brongersmai (middle), and Python breitensteini were considered one species. However, due to the different locations in which they are found, they have become three distinct species. Figure 18.12. WebADVERTISEMENTS: Speciation is the method of formation of new species. A species can be defined as one or more populations of interbreeding organisms that are reproductively isolated in nature from all other organisms.

Macroevolution is guided by sorting of interspecific variation ("species selection"), as opposed to sorting of intraspecific variation in microevolution. Species selection may occur as (a) effect-macroevolution, where organism-level traits (aggregate traits) affect speciation and extinction rates, and (b) strict-sense species … in charge of your life

WebSpeciation, or the process that results in new species, occurs when an ancestral population splits into two or more descendant species which are genetically distinct and unable to interbreed (per the biological species concept). Speciation is all about gene flow —or lack thereof. The less gene flow, the more likely speciation is to occur .
