Evolution in the Brain, Evolution in the Mind: The Hierarchical Brain and the Interface between Psychoanalysis and Neuroscience
This article first aims to demonstrate the different ways the work of the English neurologist John Hughlings Jackson influenced Freud. It argues that these can be summarized in six points. It is further argued that the framework proposed by Jackson continued to be pursued by twentieth-century neuroscientists such as Papez, MacLean and Panksepp in terms of tripartite hierarchical evolutionary models. Finally, the account presented here aims to shed light on the analogies encountered by psychodynamically oriented neuroscientists, between contemporary accounts of the anatomy and physiology of the nervous system on the one hand, and Freudian models of the mind on the other. These parallels, I will suggest, are not coincidental. They have a historical underpinning, as both accounts most likely originate from a common source: John Hughlings Jackson's tripartite evolutionary hierarchical view of the brain

Possible evidence for intraspecific aggression in a pliocene crocodile from north Queensland
A large, fossilised crocodilian metatarsal has been recovered from the Pliocene Bluff Downs Local Fauna exhibiting proliferative bone growth consistent with an episode of osteoperiostitis, possibly resulting from trauma. The nature and location of this trauma suggests that it may have occurred as a result of intraspecific aggression between rival animals. Three crocodilian genera have been recovered from the Fluff Downs Fauna, Crocodylus, Quinkana and Pallimnarchus. The metatarsal does not conform to Crocodylus porosus and therefore most probably represents one of the other two known crocodilian taxa The nature of the injury suggests that it occurred in water and it may belong to the now extinct Plio-Pleistocene Pallimnarchus rather than Quinkana babarra which is interpreted as being predominantly terrestrial
