“…These are less adequate in lower vertebrates, but are often good enough to enable one to estimate total brain size. H undreds of fossil vertebrate endocasts are available for study, and together they provide a detailed record of the history and evolution of the brain (Blumenberg 1983;Edinger 1975;Hopson 1979;Jerison 1973;Radinsky 1979). Although there is occasionally some disagreement on method, it is relatively easy to estimate body size in fossil species in which enough skeletal m aterial has been preserved.…”

There is no consensus on the nature of animal intelligence despite a century of research, though recent work on cognitive capacities of dolphins and great apes seems to be on one right track. The most precise quantitative analyses have been of relative brain size, or structural encephalization, undertaken to find biological correlates of mind in animals. Encephalization and its evolution are remarkably orderly, and if the idea of intelligence were unknown it would have to be invented to explain encephalization. The scientific question is: what behaviour or dimensions of behaviour evolved when encephalization evolved? The answer: the relatively unusual behaviours that require increased neural information processing capacity, beyond that attributable to differences among species in body size. In this perspective, the different behaviours that depend on augmented processing capacity in different species are evidence of different intelligences (in the plural) that have evolved.

“…Detailed analysis of Lucy's bone structure indicates that the Australopithecines were small of stature, walked upright, and had somewhat humanlike faces (Lovejoy 1988). Their brains, however, were not much larger than ape brains, averaging about 450 cubic centimeters (Blumenberg 1983;Corballis 1991). About 2 million years ago Homo habilis emerged.…”

Future developments in artificial intelligence (AI) will likely allow for a greater degree of human-machine convergence, with machines becoming more humanlike and intelligent machinery becoming more integrated into human brain function. This will pose many ethical challenges, and the necessity for a moral framework for evaluating these challenges will grow. This paper argues that community concern constitutes a central factor in both the evolution of religion and the human brain, and as such it should be used as the organizing principle for moral evaluations of AI technologies.

“…There is no doubt that hominid brain size increased almost three times during the last 3 million years (Tobias 1971, 1975a, Beals et al 1984, Blumenberg 1983. Mathematical analysis of this increase (Henneberg 1987) winian model of gradual evolution under conditions of self-amplifying feedback.…”
