abstract = {It has been argued that changes in the relative sizes of
visual system structures predated an increase in brain size
and provide evidence of brain reorganization in hominins.
However, data about the volume and anatomical limits of
visual brain structures in the extant taxa phylogenetically
closest to humans-the apes-remain scarce, thus complicating
tests of hypotheses about evolutionary changes. Here, we
analyze new volumetric data for the primary visual cortex
and the lateral geniculate nucleus to determine whether or
not the human brain departs from allometrically-expected
patterns of brain organization. Primary visual cortex
volumes were compared to lunate sulcus position in apes to
investigate whether or not inferences about brain
reorganization made from fossil hominin endocasts are
reliable in this context. In contrast to previous studies,
in which all species were relatively poorly sampled, the
current study attempted to evaluate the degree of
intraspecific variability by including numerous hominoid
individuals (particularly Pan troglodytes and Homo sapiens).
In addition, we present and compare volumetric data from
three new hominoid species-Pan paniscus, Pongo pygmaeus, and
Symphalangus syndactylus. These new data demonstrate that
hominoid visual brain structure volumes vary more than
previously appreciated. In addition, humans have relatively
reduced primary visual cortex and lateral geniculate nucleus
volumes as compared to allometric predictions from other
hominoids. These results suggest that inferences about the
position of the lunate sulcus on fossil endocasts may
provide information about brain organization.},
