An initial pulse of evolution produced a slew of new species with different body shapes, which lent support to the idea that speciation is concentrated near the beginning of an adaptive radiation. There is no reason why there might not be more than two species formed at one time except that it is less likely and such multiple events can also be conceptualized as single splits occurring close in time.

Here are some suggestions for effectively using it in the classroom: NOVAs collection of evolution resources includes free episodes, articles, and interactives that cover numerous evolution topics. Prezygotic mechanisms include traits that allow the individuals to find each other, such as the timing of mating, sensitivity to pheromones, or choice of mating sites. These individuals would immediately be able to reproduce only with those of this new kind and not those of the ancestral species. The topics covered include adaptation, natural selection by predation, speciation, and reproductive barriers. Postzygotic mechanisms include genetic incompatibilities that prevent proper development of the offspring, or if the offspring live, they may be unable to produce viable gametes themselves as in the example of the mule, the infertile offspring of a female horse and a male donkey.
