Quantitative immunological studies of the albumins of several species of fire bellied toads, genus Bombina.
1. Rabbit antisera against purified serum albumin of Bombina bombina were used to study relationships between B. bombina, B. variegata, and B. orientalis. 2. Quantitative micro-complement fixation tests indicated the albumins of B. bombina from central Poland and Bulgaria were indistinguishable. The albumins from several populations of B. variegata differed very slightly from that of B. bombina. The albumin of B. orientalis was quite distinct from that of B. bombina. 3. Using albumin as a molecular clock, we estimated B. bombina and B. variegata diverged within the last million years, whereas the B. orientalis lineage diverged roughly 10-12 mil yr ago.
