An Evolutionist Visits the 43rd Annual Maize Genetics Conference

Veterinary Orthopedic Society 43rd Annual Conference Abstracts

Introduction: No studies have directly compared the accuracy of ultrasound and MRI for diagnosing medial meniscal pathology in dogs with CCL disease. Further, no assessment of ultrasound has been made when ultrasound is performed by a veterinary surgeon. Materials and Methods: A prospective clinical trial was performed in which 31 stifles in 26 dogs diagnosed with CCL disease had ultrasound, MR...

The 46th Annual Maize Genetics Conference. Unlocking the secrets of the maize genome.

For the first time in its history, the Annual Maize Genetics Conference was held in Mexico City, near the center of origin for many Zea species, including maize. Maize research has made many contributions to our understanding of plant physiology and development, the regulation of transposable elements and chromosome structure, and the epigenetic control of gene expression. In addition to the re...

The genetics of maize evolution.

Maize and its closest wild relatives, the teosintes, differ strikingly in the morphology of their female inflorescences or ears. Despite their divergent morphologies, several studies indicate that some varieties of teosinte are cytologically indistinguishable from maize and capable of forming fully fertile hybrids with maize. Molecular analyses identified one form of teosinte (Zea mays ssp. par...

An Evolutionist in an Epistemological Wonderland

The paper on cascading chromosomal speciation and hybrid sinks which follows this preface was written in 1977. It faced surprising and initially incomprehensible difficulties in reviews. The epistemology and heuristic organization of the "comparative approach'' used was incommensurable with the reviewers' Kuhnian paradigms. To provide a "key" for translating from the comparative heuristic, the ...
