Some Maladaptive Traits of Natural LanguageAritz IrurtzunCNRS-IKEROne of <strong>the</strong> biggest issues <strong>in</strong> current biol<strong>in</strong>guistics concerns <strong>the</strong> discussion of <strong>the</strong>putative adaptive nature of human language. Thus, a range of authors defend <strong>the</strong> view thatlanguage is an em<strong>in</strong>ently adaptive tool that evolved for communication purposes (cf. P<strong>in</strong>kerand Bloom (1990); P<strong>in</strong>ker and Jackendoff (2005); Givón (2009), and, basically, any major workof any functionalist trend), whereas on <strong>the</strong> opposite view, <strong>the</strong>re is also a number ofresearchers who are sceptical to <strong>the</strong> adaptationist view and who defend an exaptationistorig<strong>in</strong> of natural language (cf. Piattelli-Palmar<strong>in</strong>i (1989); Uriagereka (1998); Hauser et al.(2002); Boeckx and Piattelli-Palmar<strong>in</strong>i (2005); Chomsky (2005); Fitch et al. (2005)).In this talk, I provide a number of arguments <strong>in</strong> favour of <strong>the</strong> exaptationist view bydiscuss<strong>in</strong>g <strong>the</strong> dysfunctional nature of some well-known features of natural language. Thema<strong>in</strong> goal will not be just to po<strong>in</strong>t towards some traits that have no clear evolutionaryhistory but ra<strong>the</strong>r, to argue that, teleonomically, all <strong>the</strong>se traits should be considered asmaladaptive traits, given that <strong>the</strong>y do not lead to <strong>the</strong> highest relative fitness among <strong>the</strong>possible candidates. In o<strong>the</strong>r words, <strong>the</strong>y actually make language a worse tool forcommunication.The traits that I will discuss <strong>in</strong>clude 'universal' features such as (i) <strong>the</strong> filler-gapdependencies generated by displacements, (ii) <strong>the</strong> movement of superfluous material, (iii)<strong>the</strong> ban on particular clitic or agreement clusters (<strong>the</strong> so-called Person Case Constra<strong>in</strong>t), (iv)<strong>the</strong> morphological lacuna of verbal Wh-words, as well as some language-particular features.Due to space limitations, here I will only comment <strong>the</strong> four I just mentioned.• Displacement & Filler-Gap Dependencies: As Chomsky and o<strong>the</strong>rs have argued, <strong>the</strong>l<strong>in</strong>earization 'dilemma' of displacement structures is resolved by a deletion of all but<strong>the</strong> highest copies, however, deletion of lower copies generates filler-gapdependencies and pars<strong>in</strong>g difficulties. Here, we would have a scenario with a conflictbetween computational efficiency (remerge) and communicative efficiency (fullyspecified cha<strong>in</strong>s), <strong>the</strong> former be<strong>in</strong>g <strong>the</strong> one that is guaranteed to <strong>the</strong> detriment ofcommunicative efficiency. This, I will argue, is a signature of <strong>the</strong> fact that languagedid not evolve for externalization and communication.• Generalized Pied-Pip<strong>in</strong>g: Displacement affects more material than <strong>the</strong> specific target for<strong>the</strong> movement. A Wh-feature on e.g. an element can trigger <strong>the</strong> movement of <strong>the</strong>whole DP conta<strong>in</strong><strong>in</strong>g it, and <strong>in</strong> some languages like Basque it can even trigger <strong>the</strong>movement of CPs. This feature extends to answers, which have to match <strong>the</strong> Whphrase<strong>in</strong> <strong>the</strong> question <strong>in</strong> syntactic type, as can be seen <strong>in</strong> 1. Here, too, computationalefficiency is guaranteed (attract<strong>in</strong>g <strong>the</strong> closest element with <strong>the</strong> Wh/focus feature(after percolation)), not communicative efficiency (express<strong>in</strong>g just <strong>the</strong> sufficient<strong>in</strong>formation to identify <strong>the</strong> variable <strong>in</strong> <strong>the</strong> Wh-question).(1) A. Which girl came late? (<strong>in</strong> a situation where we have to decidebetween a girl with a red coat and a girl with a blue coat)B. *Red./The girl with a red coat.
• The lack of verbal Wh-words: All natural languages appear to have Wh-words forarguments (who, what) and adjuncts (where, why). However, crossl<strong>in</strong>guistically, wef<strong>in</strong>d no purely monomorphemic verbal Wh-words like 2. This restricts <strong>the</strong> range ofpossible expressions of natural languages. Aga<strong>in</strong>, no clear functionalist scenario canbe imag<strong>in</strong>ed for <strong>the</strong> development of such a lacuna; I will argue that it is due to ageneral formal requirement for DPs to get θ-roles.(2) Whxyzed Brutus Caesar?Wh.VERB Brutus CaesarWhat type of event has Brutus as <strong>the</strong> subject and Caesar as <strong>the</strong> object?• The Person Case Constra<strong>in</strong>t: In languages with agreement morphology or clitics, <strong>the</strong>comb<strong>in</strong>ation of dative agreement/clitic with 1 st or 2 nd person accusativeagreement/clitic is banned (3) (cf. Bonet (1994)). Aga<strong>in</strong>, this restriction on what are <strong>the</strong>possible expressions of natural languages has no possible communicative orig<strong>in</strong> but aplausible computat<strong>in</strong>al one (cf. Ormazabal (2000)).(3) *Pedro le me envía.Pedro cl.3D cl.1A sendPedro sends me to him/her/itThe corollary of my presentation will be that <strong>the</strong>re is a wide range of features ofnatural language that are maladaptive stricto sensu (cf. Crespi (2000)), and hence, naturallanguage cannot be considered a tool evolved under communicative pressures, but ra<strong>the</strong>r <strong>the</strong>product of a complex emergence with exapted traits.ReferencesBoeckx, C., and M.
