Third, the frequency with which peripatric speciation occurs is rare, and fourth, the period of transition between parent and daughter species is short compared to the time of the species existence as a distinct form.
It is the classic example of metasystem transition in biology. Its first tenet emphasizes the involvement of cladogenesis, whereas the second asserts that allopatric and peripatetic speciation apply to modern populations. Third, the frequency with which peripatric speciation occurs is rare, and fourth, the period of transition between parent and daughter species is short compared to the time of the species existence as a distinct form. It states that short, rapid burts, not constant rates, characterize evolutionary change. FTP, name this theory put forth by Niles Eldridge and Stephen Jay Gould.
