Schistosomatidae is a family of parasites that infect the blood vessels of mammals and birds. The parasites have a complex life cycle that requires at least two hosts: an aquatic snail (usually freshwater), and either a bird or a mammal. Blood flukes cause devastating pathologies in hosts, and are difficult to reconcile with a creation that God declares to be "good" (Genesis 1). This paper aims to determine the number of created kinds represented in this family of parasites, the original hosts for these animals, and the diversification pattern and events that produced the current species. We employed a statistical baraminic study to detect evidence of continuity within family Schistosomatidae and any discontinuity between members of the family and other blood parasites. We also compared the pathologies, geographic ranges, and host specificities of bird schistosomes and mammal schistosomes to provide information on the original hosts and diversification pattern. Members of family Schistosomatidae appear to represent a single created kind that is distinct from the members of other families of blood parasites. Bird schistosomatids are generally less pathogenic than their mammal counterparts, and have wider geographic ranges and less host specificity. Schistosomatidae may represent a single created kind that was created to live within one or several kinds of birds, providing some benefit to its host. As members of this kind moved into different hosts or diversified along with its host, they ceased providing any benefit to their symbiotic partner. The resulting species are some of the most important and dangerous organisms on earth.
