Q: A specific form of this process is graphically represented as "dumbbell shaped" and is alternatively called vicariant. In a 1977 paper, Jared Diamond discussed the "inter-archipelagial" and "continental" method of this process, the latter of which is only applicable to birds. Two ways in which this process can occur are ploidy changes, and hybridization, and it can also occur due to adaptive radiation. The rate of the occurrence of this process is often disrupted in punctuated equilibrium, and it exists in peripatric, sympatric, and allopatric varieties. For 10 points, name this biological process which makes a group of organisms unable to interbreed with another.
