Only in placental mammals will the atrial septum form by the coming‐together of the septum primum and the septum secundum. In up to one of four placental mammals, this complex morphogenesis is incomplete and yields patent foramen ovale. The incidence of incomplete atrial...
With approximately 7000 species, snakes and lizards, collectively known as squamates, are by far the most species‐rich group of reptiles. It was from reptile‐like ancestors that mammals and birds evolved and squamates can be viewed as phylogenetically positioned between them and fishes. Hence, their hearts have been studied for more than a century yielding insights into the group itself and into the...
