At some point in hominid evolution, a mutation may have produced a" dextral"(D) allele,
strongly biasing handedness in favor of the right hand and control of speech toward the left …

Within the evolutionary framework about the origin of human handedness and hemispheric
specialization for language, the question of expression of population‐level manual biases in …

A labor of love and enthusiasm as well as deep scientific knowledge, Right Hand, Left Hand
takes the reader on a trip through history, around the world, and into the cosmos, to explore …

This book explores the origin and evolution of speech. The human speech system is in a

The last decade has seen a resurgence of interest in laterality of function in primates,
especially in hand use as it links to handedness and language in Homo sapiens. Manual …

This study describes the use of referential gestures with concomitant gaze orienting
behavior to both distal food objects and communicative interactants by 115 chimpanzees …

The spontaneous index finger and other referential pointing in 3 adult, laboratory
chimpanzees (Pan troglodytes) who have not received language training is reported. Of 256 …

Neural changes that occurred during human evolution to support language are poorly
understood. As a basis of comparison to humans, we used design-based stereological …

Population-level right-handedness is a defining characteristic of humans. Despite extensive
research, we still do not know the conditions or timing of its emergence in human evolution …

Historically, population-level handedness has been considered a hallmark of human
evolution. Whether nonhuman primates exhibit population-level handedness remains a …
