Cranial Morphology of the Therian Common Ancestor, as Suggested by the Adaptations of Neonate Marsuductive biology of marsupials may be reminiscent of a primitive ovo-viviparous phase of therian evolution. Therefore, it seemed rewarding to test the hypothesis that the skull structures of neonatal didelphids may be adapted to such a primitive mode of development as well. It is assumed that the hea

An Ontogenetic Assessment of Dental Homologies in Therian Mammals,ant therian mammals. In addition, these developmental data offer evidence for the loss of teeth during mammalian evolution. Such studies can distinguish the deciduous or successional nature of individual teeth, even when replacement does not occur postnatally. Ontogenetic analyses also provide evide

Theria of Metatherian-Eutherian Grade and the Origin of Marsupials,d the origin of Marsupialia remain poorly understood, largely because the nature of the fossil record severely restricts the data available. Phylogenetic analysis suggests that the early history of tribosphenic mammals was complex. One group of archaic Tribosphenida, including . and presumed allies,

As of this writing, a different popular attitude prevails from that when the ASI was proposed as far as how critical the world energy picture is. In the popular press, a panglossian attitude (the "petroleum glut" of the 80‘s) has replaced
