Monkey homologues of language areas: computing the ambiguities

Abstract: The ‘language-readiness’ of human brains most probably resulted from modification of structures present in non-human primate brains, but identifying such homologues and the nature of their modifications has been highly problematic. In a recent article,...

Rethinking mammalian brain evolution

SYNOPSIS. A critical review of past and current theories of mammalian brain evolution is presented in order to discuss conceptual problems that persist in the field. Problems with the concept of homology arise because of the interaction of cell lineages and...

Fallacies of progression in theories of brain-size evolution

Abstract: The tacit assumption that relative enlargement and differentiation of brains reflect a progressive evolutionary trend toward greater intelligence is a major impediment to the study of brain evolution. Theories that purport to establish a linear scale for...
