Armadillos - continued...

Newmann and Patterson published a number of papers dealing with matters of development, cytology, sex-determination and heredity in the Texas armadillo and also formulated theories about the causes of twinning, a topic of ongoing debate. After the confirmation of "specific polyembryony", the armadillo served as a powerful natural tool for investigating certain basic problems of heredity, such as the analysis of "prederminative" versus "epigenetic" factors or the limits of heredity control. However, during that time, the difficulty of raising armadillos in the laboratory meant that these animals could not become significant tools in laboratory studies. Since then the armadillos have become important as research organism in the biomedical research as they are natural hosts of several protozoal and bacterial pathogens, such as leprosy.
