Abstract:
Highly repeated DNA sequences were investigated as potential phylogenetic indicators among five species of galagines. One lorisine, one cheirogaleid, and two lemurid species were also investigated as progressively more distant outgroups. The lorisids displayed strong conservatism with regard to these sequences, to the point where the galegine species proved difficult to differentiate. When restriction fragment differences were observed, the galagine species fell into two groups: one containing the greater galagos and G. alleni and the other comprising the lesser galagos. The sequences of the cheirogaleid Microcebus murinus were found to be highly species-specific, bearing little resemblance to those of the galagines or the lemurids. Common sequences detected between M. murinus and G. senegalensis may be ancient sequences shared by all strepsirhines. © 1994 Wiley-Liss, Inc.
