In phylogenesis, the migration of function from subcortical centers to the cortex.


Increase in the ratio of brain mass to body mass during the evolution of a species or other taxonomic group. Higher degrees of encephalization are generally correlated with higher degrees of intelligence.

en·ceph′a·lize v.


The increase of brain size relative to body size, which is intimately linked with human evolution.

So, it was the development and deepening of the angelically / protection ecological relationship which concerned with the generation and intensification of the tightest attachment amongst the parents and the progeny, all living within the nuclear group which becomes parallel with the increasing of a major complexity and major tightness need of the new-born dependence to the parents, especially growing in those species endowed with a major brain capacity and most complex encephalization.
The pattern of human evolution: studies on bipedalism, mastication and encephalization.
Complex adaptations tend to evolve gradually (Dawkins, The Blind Watchmaker; and Williams), and the trend toward encephalization is no exception.
Ecology and energetics of encephalization in hominid evolution.
Due to an encephalization of the ganglionic masses in cephalopods, the octopus central nervous system is more similar to the vertebrate brain than to the ganglionic chain of its close relatives like the gastropods and bivalves (Young, 1971; Kandel, 1976; Budelmann et al.
In particular, she demonstrates how critical 'episodes' in human evolution, such as terrestriality, bipedalism and encephalization, can acquire very different meanings according to their sequence in different narratives.
Encephalization, or the gradual increase in brain size relative to body mass, started a few million years ago with a basket of other changes, including erect posture and complex social adaptations.
As a central activity promoting this encephalization, language evolved to help hominids adapt better to their environment by making possible a complex level of cooperation.
The pattern of human evolution: Studies on bipedalism, astication, and encephalization.
However, if encephalization is estimated not by brain size but by the number of neurons in the brain (or by brain complexity), and the average size of neurons is directly related to genome size (and inversely to brain complexity), as the recent work on amphibians has showed (Roth et al.
