Abstract: | Immunological distances were determined for four strains of the free-living amoeba classified as Amoeba proteus, two strains classified as Polychaos dubia and a single strain classified as Chaos carolinensis. The data show that the ShP strain does not belong to the proteus group; that A. proteus is more closely related to C. carolinensis and is derived from Chaos as is the ShP strain; that P. dubia and C. carolinensis are the more distantly related species and appear to be the first of the above to have diverged from a common ancestor; and that the amoebae have a long evolutionary history. The accuracy of the phylogenetic tree and the distance Wagner network was discussed. Since the amoebae may be polyphyletic in origin, the latter was assumed to be a more accurate representation of the immunological distance data. |
