    "title": "Laterality in Animals",
    "subtitle": null,
    "abstract": "We  now know that laterality in various forms is a characteristic of a wide range of species, and that it apparently developed very early in evolution. Yet, some hundred years had to elapse after the discovery that there was lateralization, or asymmetry, for control of speech in the human brain, before any earnest attempts were  made to discover or recognise the presence of laterality in  nonhuman species (see Robinson, Becker & Camp, 1983). The reason for this delay appears to have been the belief that lateralization of brain function was a characteristic unique to the human species, placing our species above all other species. This belief had been preceded by a well-developed mythology surrounding the sinistral-dextral dichotomy of handedness in  humans (Corballis, 1983, pp. 1-9), and the belief that dextrality was also a uniquely human characteristic. It has been argued that shared tool use by  humans caused laterality of limb use and, in turn, specialization of the left hemisphere for language (Frost, 1980; Bradshaw & Nettleton, 1982). Thus, the population bias in handedness in  humans was seen to be intimately related to our superior ability to use tools, and the population bias in lateralization of function in the cerebral hemispheres was seen to be the basis of our superior ability for language. Not surprisingly, these unique attributes afforded to the human species were reluctantly relinquished by many psychologists, some (e.g. Levy, 1974, 1979) clinging to them well after lateralization of function in the nervous system had been clearly demonstrated in more than one nonhuman species, in particular for control of singing in song-birds (Nottebohm, 1971; see later).",
