Riportando dati aggiornati, si sviluppa la proposta di Deacon (2010) sul ruolo giocato da un rilassamento delle pressioni selettive nell’evoluzione del linguaggio articolato nell’uomo, fornendo un plausibile scenario evolutivo di supporto, basato sull’ipotesi dell'"auto-addomesticazione" (Gibbons, 2014). Ci si sofferma in particolare su alcuni tratti neotenici dello sviluppo, caratteristici dell’attuale Homo sapiens, sostenendo l’importanza (sia a livello individuale, sia a livello di gruppo) che questi possono aver ricoperto nel corso dell’evoluzione umana e associando la loro diffusione a un rilassamento delle pressioni selettive. Si fornisce un’ipotesi di come una simile condizione ecologica possa essere stata raggiunta, facendo riferimento alla teoria della costruzione di nicchia e portando l’esempio del controllo del fuoco. Si presentano infine alcuni possibili sviluppi dell’ipotesi qui presentata che possono risultare fecondi all’interno del dibattito sull’evoluzione del linguaggio.

Keywords: Auto-addomesticazione, Costruzione di nicchia, Evoluzione del linguaggio, Exaptation, Neotenia, Rilassamento delle pressioni selettive.
