Marmosets are exclusively arboreal‚ and one would assume that auditory signals are a particular important tool for communication‚ owing to the low visibility in trees.

Information about the age‚ sex‚ group identity‚ motivational state‚ body size‚ affective state and reproductive status of a vocalizing individual‚ and clear considerations of the behavioral and environmental context of the vocalization

PS 177 – 01 74 2/14/13 This book is not Harry Potter‚ but it is pretty magical in its own way.

The next chapter on sex explains how humans are different from every other species because humans go through extensive pair-formation‚ pre-copulatory activity‚ and then into intense copulation. The chapter on rearing follows

If this were true‚ then perhaps big-headed people wouldn’t be so pea-brained. This question is mired in many unknowns. For one‚ scientists still debate over the definition of intelligence. For any IQ definition‚ how do you measure it? Further‚ do differences in IQ show up in daily life? And finally‚ does more brain tissue or a heftier brain equate with higher IQ? One thing scientists do agree on: A big brain alone doesn’t equate with smarts. If it did‚ elephants and sperm whales would win all

The results‚ detailed in the current issue of the science journal Current Biology‚ may help to explain curiously peaceful interactions among neighboring social groups. The groups were observed in new behavioral studies of the western lowland gorilla (Gorilla gorilla gorilla). 1. The study could also provide clues about the role and development of kinship in early human society‚ say researchers behind the work. Despite being the most numerous kind of gorilla‚ the western lowland gorilla species

characteristics of the human brain requires studying the brain of other living primate species. In other words‚ a specific evolutionary change in the human brain cannot be inferred to be unique to the human lineage unless other species sharing a last common ancestor don’t have it. That being said‚ Rilling emphasizes the role of comparative neuroimaging to investigate the similarities and differences between human and non-human primate brains‚ and highlights the different imaging techniques that have been
