On ecologically heterogeneous islands, however, speciation by cladogenesis (splitting) frequently occurs, resulting in genetically closely related species which may be quite different from each other morphologically.
Subgroups join together and split apart frequently, leading researchers to describe the pattern as "fission-fusion" sociality.
The increasing distances travelled from the kebele to find pasture cause the household to split more frequently and strain social processes like dagu, a 'sophisticated system for news exchange' (Menbere and Skjerdal 2008, p. 19) which constitutes the traditional Afar means of communication across the rangelands.
Sister centromere re-association after splitting, or at least a reduction of their distance of splitting, is frequently observed during undisturbed mitotic progression (He et al. 2000; Tanaka et al. 2000; Goshima and Yanagida 2001; Pearson et al. 2001).
By Andrew Boynton April 27 , 2012The members of Alvin Ailey American Dance Theatre are adept in what might be termed "extreme dancing" — the jumps seem trampoline-enhanced, the splits are frequently beyond a hundred and eighty degrees, and the drama is off the charts.

Similar cases can be observed between the comparison of catfish and medaka, catfish and Tetraodon, catfish and stickleback, indicated that chromosomal fusions or splits occurred frequently during the teleost evolution.
Computer-aided molecular design is frequently split into disciplines that focus on either structure-based or ligand-based methods.
