Each student (or group) will create multiple species that have evolved together in the same environment and therefore contain structure that are evident of convergent evolution, divergent evolution, and coevolution. 1. event, like an earthquake or a landslide separates a population. and fully. The final synthesis question asks to explore how reproductive isolation differs for each mode. Diversifying selection can also occur when environmental changes favor individuals on either end of the phenotypic spectrum. These offsprings seems to be fertile since the study found traces of Neanderthals DNA in modern humans. However, it is more common for the process to be extended over many generations (up to millions; Coyne & Orr 1997, 2004).The process is continuous, but it may be helpful to ask what initiates the evolution of intrinsic reproduction isolation, what causes isolation to increase (in terms of both .

Your students will love filling in and coloring their notes. Also Read: Concept of Species. Other scenarios on the list describe behavioral isolation, chemical isolation, and temporal isolation. Sometimes barriers, such as a lava flow, split populations by changing the landscape. The term speciation refers to the origin of new species. Summarizes the 3 main methods of reproductive isolation: geographic is, In brief, students begin by generating questions based upon experimental results (Powerpoint Slide included). The definition of "species" is hotly debated among evolutionary biologists and none of the (numerous) proposed definitions seems to adequately cover all cases. Boggs, in International Encyclopedia of the Social & Behavioral Sciences, 2001 3.2 Parapatric Speciation 'Parapatric' derives from 'para' meaning 'near' and 'patria' meaning 'country.'

They read short scenarios and identify what types of isolating mechanisms are being described. (see, Hybridization is known to happen between what are generally accepted to be different species sometimes this leads to new species, other times some traits from one species become incorporated into another species.
