DarwinC. An interesting geographical pattern has been discovered in this group. Interfamilial G-band homeologies have been identified Buckland and Evans among the cow family Bovidaedeer family Cervidae and the giraffe family Giraffidae. Honacki, and D. That changes have occurred in organisms since creation is not in question, but the extent of those changes is uncertain.

If their karyotypes are derived from the presumed ancestral karyotype for the group, Robertsonian rearrangements predominate in the species reconstructing sex chromosome evolution games in West Midlands Galagowhile pericentric inversions are more important in Perodicticusa loris Dutrillaux et al.

Several families of mostly South American rodents are included in the hystricomorphous rodents. If one assumes that two similar species do in fact have a common ancestor, then one is committed to finding a way of matching the banding patterns.

Do they provide any support for common design? Obviously, such cladograms cannot be more accurate than the identification of banding homeologies. Rofe compared the G-bands of ten species of kangaroos and their allies, with 2n ranging from 10 to There have been some suggestions that karyotypic structure has adaptive significance Baker et al.

Koop, and M. The two species of horses have similar chromosomal banding patterns, as do the two species of asses. Meckvichal, A. The lack of chromosomal divergence despite the geographical isolation is unexpected, and suggests either a very stable karyotype or a relatively short period of isolation, or both.

Buckland and Evans , using the goat karyotype as a standard, found nearly complete agreement in banding patterns among several species of bovids, representing three subfamilies.
