Developmental structure in brain evolution

Behavioral and Brain Sciences, 2001
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 ...

Evolution of developmental rate in mammals

Experimental Gerontology, 1982
The allometric relationship between gestation period and body mass in terrestrial placental mammals was analyzed using data from 147 species. Important differences were found among the various orders. These differences can be explained if it were assumed that the order-specific lifestyle and environment in which the young are born has caused different ...

Developmental basis of limb evolution

The International Journal of Developmental Biology, 2002
Can developmental processes account for vertebrate limb homology, the overall similarity of definitive limb structure despite differences in different taxa which often relate to evolutionary adaptations? Relevant evidence is from molecular studies, from 'cut & paste' experimental embryology and from classical descriptive accounts of embryology and ...

On the importance of evolution to developmental psychobiology

Developmental Psychobiology, 1995
AbstractThe termdevelpomental psychobiologyimplies an integration between psychology and biology. But what segment of biology does the discipline embrace? The present commentary asserts that developmental psychobiology devotes too much attention to structural biology, with its emphasis on proximate mechanisms, and fails to give enough prominence to ...

EVOLUTION OF DEVELOPMENTAL STRATEGIES IN PARASITIC HYMENOPTERA

Annual Review of Entomology, 2006
▪ Abstract  Parasitoid wasps have evolved a wide spectrum of developmental interactions with hosts. In this review we synthesize and interpret results from the phylogenetic, ecological, physiological, and molecular literature to identify factors that have influenced the evolution of parasitoid developmental strategies. We first discuss the origins and

Evolution of developmental mechanisms in nematodes

Journal of Experimental Zoology, 1999
The recent findings that key developmental genes are conserved across animal phyla have led to descriptions of evolutionary change in development based on the recruitment of these few molecules. This approach, however, encounters problems in assigning homology across long evolutionary distances.

The Evolution of Intelligent Developmental Systems

2013
This chapter aims to understand the relations between the evolution and development of complex cognitive functions by emphasizing the context of complex, changeable environments. What evolves and develops in such contexts cannot be achieved by linear deterministic processes based on stable "codes".

Developmental plasticity and evolution

Choice Reviews Online, 2003
The first comprehensive synthesis on development and evolution: it applies to all aspects of development, at all levels of organization and in all organisms, taking advantage of modern findings on behavior, genetics, endocrinology, molecular biology, evolutionary theory and phylogenetics to show the connections between developmental mechanisms and ...

The Evolution of Developmental Psychology

Human Development, 2009
Three different handbooks from child psychology, whose publication dates span 40 years, and BIRREN’s [1959] handbook on the psychology of aging were subjected to quantitative and qualitative comparative analyses. The assumption underlying these analyses was that the differences existing among the compendia are reflective of the changes that have ...
