  Together, as Kuhl 1994, 2000 argues, these findings cast doubt on  the language-specificity of the inborn perceptual and categorization  capacities that form the basis of human phonological learning. For  given the fact that human (and animal) perception quite generally is  categorical, it is arguable that languages have evolved so as to  exploit the perceptual distinctions that humans are able to make,  rather than humans' having evolved the abilities to make just the  distinctions that are made in human languages, as a view like Eimas'  would suggest.
