Earth oven cooking is very important among the Yucatec Maya. It is used for daily, festive, and ceremonial occasions, contrasting with other Mesoamerican cultures that use this technique sporadically. In this paper we present an ethnobotanical analysis of the use of earth ovens in a Maya community in Yucatan, Mexico, and discuss its possible antiquity, probable reasons for its continuity, and its current and past importance. We found four oven types in daily use as well as in ritual and celebratory contexts. These involve both men and women in a way that favors transmission of traditional knowledge to the next generation and promotes social bonding and ethnic identity. Of the 46 plant species used in their construction or for the dishes cooked in them, 82% are native and produced in traditional agricultural systems: milpa (kool in Maya) maize-bean-squash association and conuco (pach pakal in Maya) based on tubers such as manioc (Manihot esculenta Crantz). Research suggests that this food preparation technology has the same antiquity as its associated agricultural systems (approximately 3400 to 3000 B.C.E.). Earth ovens were probably used to cook roots and meat in the Archaic and then to cook tamales (vegetal-wrapped maize dough) beginning in the Preclassic. Continuity of traditional agricultural and cultural practices has favored preservation of earth ovens.

To document the diversity of geographic (physical and human) influences on seed exchange, an important component of traditional agricultural systems, household surveys were conducted in four villages in the Mexican Bajío. This research reviews and contributes to an understanding of the purpose, structure, and scale of seed exchange and threats to seed movement. Based on the household survey data, the

T. H. Morgan, A. H. Sturtevant, H. J. Muller and C. B. Bridges published their comprehensive treatise The Mechanism of Mendelian Heredity in 1915. By 1920 Morgan's "Chromosome Theory of Heredity" was generally accepted by geneticists in the United States, and by British geneticists by 1925. By 1930 it had been incorporated into most general biology, botany, and zoology textbooks as established knowledge. In this paper, I examine the reasons why it was accepted as part of a series of comparative studies of theory-acceptance in the sciences. In this context it is of interest to look at the persuasiveness of confirmed novel predictions, a factor often regarded by philosophers of science as the most important way to justify a theory. Here it turns out to play a role in the decision of some geneticists to accept the theory, but is generally less important than the CTH's ability to explain Mendelian inheritance, sex-linked inheritance, non-disjunction, and the connection...
