One thought on “Marsupials are a missing link in vertebrate development”

  1. Great work. Same Flynn and Hill mentioned above published beautiful studies on monotreme early development. No molecular analysis on early lineage segregation in monotremes yet but they are more akin to reptilians (including birds) and similar studies with monotreme embryos would definitely shed more light on how eutherians evolved stepwise from stem amniotes. This and recent publications on lineage segregation in human preimplantation embryos give one perspective on genetic models.
