布罗德曼区44描绘了人脑额下回内的布罗卡区的一部分，并且是言语产生的关键区域，左半球比右半球大，-这种不对称性与语言优势有关。在这里，我们表明，有一个类似的不对称性，在这方面，也与左半球的优势，在三个大猿物种（黑猩猩，潘paniscusandGorilla大猩猩）。我们的研究结果表明，左半球在语言产生中占主导地位的神经解剖学基础至少在500万年前就很明显了，并且不是原始人类进化所独有的。
Brodmann's area 44 delineates part of Broca's area within the inferior frontal gyrus of the human brain and is a critical region for speech production,, being larger in the left hemisphere than in the right,,,— an asymmetry that has been correlated with language dominance,. Here we show that there is a similar asymmetry in this area, also with left-hemisphere dominance, in three great ape species (Pan troglodytes, Pan paniscusandGorilla gorilla). Our findings suggest that the neuroanatomical substrates for left-hemisphere dominance in speech production were evident at least five million years ago and are not unique to hominid evolution.
