Abstract

Although it is commonly accepted that brains work as functionally distributed systems in which interconnected structures work together in processing particular types of information, few studies have investigated the evolution of functionally specialized neural systems across many different lineages. MR‐related research has provided in‐depth information on connectivity patterns, but because of its focus on particular species, it has given only indicative clues about evolutionary patterns shaping brain organization across primates. Here, we combine depth with breadth of analysis by investigating patterns of covarying size evolution in substructures of the cortico‐cerebellar system across 19 anthropoid species spanning 35 million years of divergent evolution. Results demonstrate two distinct patterns of size covariation in substructures of the cortico‐cerebellar system, suggesting neural systems involving profuse cortico‐cerebellar connections are a major factor in explaining the evolution of anthropoid brain organization. We set out an evolutionary model of relative cortico‐cerebellar expansion and provide a detailed picture of its branch‐specific evolutionary history suggesting the ape radiation is the clade with the strongest and most consistent evolutionary history in relative (frontal) cortico‐cerebellar expansion.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • There is a striking correspondence between the patterns of correlated evolution among specific components of the cortico-cerebellar system and their anatomical connectivity, down to the level of individual nuclei.

    “Second, there is a striking correspondence between the patterns of correlated evolution among specific components of the cortico-cerebellar system and their anatomical connectivity, down to the level of individual nuclei [62,67].”

    From Embodied cognitive evolution and the cerebellum (2012) · cites this paper as [62]

  • Recent allometric analyses reveal that, although absolute and proportional frontal region size increased rapidly in hominins, this change was associated with size increase in other areas and whole brain size, rather than with specialization for enlarged frontal lobes specifically.

    “Recent allometric analyses reveal that, although absolute and proportional frontal region size increased rapidly in hominins, this change was associated with size increase in other areas and whole brain size, rather than with specialization for enlarged frontal lobes specifically [57,61–63].”

    From Embodied cognitive evolution and the cerebellum (2012) · cites this paper as [62]

  • The importance of the frontal lobes in cognitive evolution needs to be interpreted in terms of the areas with which they connect and with which they have co-evolved, including the cerebellum.

    “This does not suggest that the frontal lobes were unimportant in cognitive evolution, just that their importance needs to be interpreted in terms of the areas with which they connect and with which they have co-evolved, including the cerebellum [61,62].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
