How does evolution grow bigger brains? It has been widely assumed that growth of individual structures and functional systems in response to niche-specific cognitive challenges is the most plausible mechanism for brain expansion in mammals. Comparison of multiple regressions on allometric data for 131 mammalian species, however, suggests that for 9 of 11 brain structures taxonomic and body size factors are less important than covariance of these major structures with each other. Which structure… Expand
Mosaic evolution of brain structure in mammals
TLDR
Comparative data is analysed to demonstrate that mosaic change has been an important factor in brain structure evolution, and shows that brain structures with major anatomical and functional links evolved together independently of evolutionary change in other structures. Expand
Understanding the Evolution of Mammalian Brain Structures; the Need for a (New) Cerebrotype Approach
TLDR
The cerebrotype approach developed here could constitute an adequate level of analysis for evo-devo studies, and by extension, for a wide range of disciplines related to brain evolution. Expand
Evolution of the human brain: when bigger is better
  • M. Hofman
  • Medicine, Computer Science
  • Front. Neuroanat.
  • 2014
TLDR
The object of this review is to present current perspectives on primate brain evolution, especially in humans, and to examine some hypothetical organizing principles that underlie the brain's complex organization. Expand
Brain Evolution in Vertebrates
Over evolutionary time, vertebrate brains have expanded and become more structurally complex, with the forebrain having the largest increase in relative volume and cortical folding. There areExpand
Brain size expansion in primates and humans is explained by a selective modular expansion of the cortico-cerebellar system
TLDR
Results suggest that the expansion of the CCS is the primary driver of brain expansion in anthropoid primates, and these findings have fundamental implications for the nature of primate and human cognition, and the genetic and developmental structure that underpins brain evolution. Expand
3.05 – Cortical Evolution as the Expression of a Program for Disproportionate Growth and the Proliferation of Areas
TLDR
The insensitivity of the relative size of cortical areas to environmental niche, in combination with many observations of the ease of developmental reallocation of cortex suggests that genetic selection on the size of particular cortical areas is not a common evolutionary event. Expand
Brain reorganization, not relative brain size, primarily characterizes anthropoid brain evolution
  • J. Smaers, C. Soligo
  • Biology, Medicine
  • Proceedings of the Royal Society B: Biological Sciences
  • 2013
TLDR
Patterns of mosaic change in brain evolution are identified that mirror brain systems previously identified by electrophysiological and anatomical tract-tracing studies in non-human primates and functional connectivity MRI studies in humans and demonstrate deep evolutionary roots for mosaic patterns associated with motor control and learning.

Précis of Principles of Brain Evolution
  • G. Striedter
  • Psychology, Medicine
  • Behavioral and Brain Sciences
  • 2006
TLDR
This book delves into rules of brain development and asks how changes in brain structure impact function and behavior, and focuses specifically on how mammal brains diverged from other brains and how Homo sapiens evolved a very large and “special” brain. Expand
Evolution of brain region volumes during artificial selection for relative brain size
TLDR
The results suggest that brain regions respond similarly to strong directional selection on relative brain size, which indicates that brain anatomy variation in contemporary species most likely stem from direct selection on key regions. Expand
Primate brain evolution: Integrating comparative, neurophysiological, and ethological data
TLDR
Recent work demonstrates the value of examining how evolutionary changes at different anatomical levels interrelate, and takes great care in the use of comparative methods and in finding multiple converging strands of comparative evidence. Expand

Implications of the “initial brain” concept for brain evolution in Cetacea
TLDR
Although the dolphin brain has certain quantitative characteristics of the evolutionary changes seen in the higher terrestrial mammals, it has also retained many of the conservative structural features of the initial brain, and its neocortical organization is accordingly different, largely in a quantitative sense, from that of terrestrial models of theInitial brain such as the hedgehog.

Patterns of Vertebrate Neurogenesis and the Paths of Vertebrate Evolution
TLDR
Changes in overall rate of neural maturation distinguish related subclasses, such as marsupial and placental mammals, and changes in duration of neurodevelopment distinguish species within subclasses. Expand

TLDR
The primary proposition put forth is that the mammalian neocortex is relatively unspecified by strict genetic means, and that this allowed the neocortex to expand and adapt to a variety of circumstances during the course of phylogeny. Expand

TLDR
Changes in the generation and specialization of neurons, alterations in the developmental timing that modify internal and external influences on neuron activity patterns seem to have a major role in the construction and maintenance of organization in the nervous system. Expand
Evolution and ontogeny of neural circuits
TLDR
These findings suggest that in many neuronal systems axons do not invade unknown territories during evolutionary or ontogenetic development but follow in their ancestors' paths to their ancestral targets; if the connection is later lost, it reflects the specialization of the circuitry. Expand

I would like to take advantage of this forum to speculate on the relationship of encephalization to current research on the ontogenetic regulation of neuron number and type in the cortex. Expand
Relative brain size and basal metabolic rate in terrestrial vertebrates
TLDR
Re-examination of brain–body size relationships for large samples of species from three major vertebrate groups now shows that there is no empirical foundation for the concept of scaling to body surface area, and it seems that brain size may be linked to maternal metabolic turnover. Expand
