{"DOI":"10.20944/preprints201909.0192.v1","abstract":"The vertebrate anterior-posterior (A-P = craniocaudal) axis is evidently made by a timing mechanism. Evidence has accumulated that tentatively identifies the A-P timer as being or involving Hox temporal collinearity. Here, I focus on the two current competing models based on this premise. Common features and points of dissent are examined and a common model is distilled from what remains. This is an attempt to make sense of the literature.","author":[{"family":"Durston","given":"A.J.Durston"}],"id":"unknown","issued":{"date-parts":[[2019,9,17]]},"publisher":"MDPI AG","title":"Some Questions and Answers About the Role of Hox Temporal Collinearity in Vertebrate Axial Patterning","type":"post"}
