Local species, the market, and transportation in embryological research: the study of polyembryony in armadillos in the early twentieth century. Susana V. The article examines the general affirmation that communication networks and mobility are important to science by examining how these factors played a relevant role in one specific case, that is, research on the embryology of certain species of armadillos in the early twentieth century. As we show, access to pregnant females of the species and transport time from the wild to the laboratory were significant issues in the early days of such research. The strategies used to obtain field samples, the temporality of certain phenomena, the commercial circuits of which the organisms under study were a part, and the transformations they underwent in the laboratory all afford a glimpse at some aspects of how these scientists approached their work and what problems they faced in producing new knowledge. Keywords: history of embryology, armadillos, scientific practices, polyembryony.

Any of the three primary layers formed in the early development of the embryo, the ectoderm, endoderm, or mesoderm, which give rise to specific tissues of the body. Gastrulation continues during the second week with the formation of the "epiblast", and is completed during the third week with the formation of the three "primary germ layers": ectoderm, mesoderm, and endoderm.
