Attempts to solve the fundamental questions regarding the descent of man are dogged by superstitions and unexamined orthodoxies. The origin of humans, established a decade ago based upon cytological analysis of ape chromosomes, continues to be called into question. Although molecular methods have provided a framework for tracing the paths of human evolution, conclusive evidence remains elusive. We have used a single ABL gene probe derived from human chromosome 9 to assess the direction of change in the equivalent ape chromosomes. This approach has resulted in a few surprises which again challenge the prevailing view of early primate evolution based solely on chromosome banding patterns. The ABL proto-oncogene is present on human chromosome 9 at band q34. Similar DNA sequences presumed to represent an ABL gene, are present on chromosome 11 in chimpanzee (Pan troglodytes) but at a different relative location, indicating that the mechanism of the origin of human chromosome 9 is far more complex than has previously been suggested. Nevertheless, in gorilla (Gorilla gorilla) and orangutan (Pongo pygmaeus), the equivalent to human chromosome band 9 q34 is apparently located on chromosome 13 at a putative telomeric position and no discernible differences could be established. Despite the presence of the ABL protooncogene on human equivalent ape chromosomes, molecular systematics will continue to generate enigmas in the evolutionary context until the entire genome is sequenced.
