Abstract: Talk of linguistic universals has given cognitive scientists the impression that languages are all built to a common pattern. In
fact, there are vanishingly few universals of language in the direct sense that all languages exhibit them. Instead, diversity can be found
at almost every level of linguistic organization. This fundamentally changes the object of enquiry from a cognitive science perspective.
This target article summarizes decades of cross-linguistic work by typologists and descriptive linguists, showing just how few and
unprofound the universal characteristics of language are, once we honestly confront the diversity offered to us by the world's 6,000
to 8,000 languages. After surveying the various uses of "universal," we illustrate the ways languages vary radically in sound,
meaning, and syntactic organization, and then we examine in more detail the core grammatical machinery of recursion,
constituency, and grammatical relations. Although there are significant recurrent patterns in organization, these are better explained
as stable engineering solutions satisfying multiple design constraints, reflecting both cultural-historical factors and the constraints of
human cognition.
Linguistic diversity then becomes the crucial datum for cognitive science: we are the only species with a communication system that
is fundamentally variable at all levels. Recognizing the true extent of structural diversity in human language opens up exciting new
research directions for cognitive scientists, offering thousands of different natural experiments given by different languages, with
new opportunities for dialogue with biological paradigms concerned with change and diversity, and confronting us with the
extraordinary plasticity of the highest human skills.

1990) supposedly common to all languages
1. "Major lexical categories (noun, verb, adjective, preposition)" (! sect. 2.2.4)
2. "Major phrasal categories (noun phrase, verb phrase, etc.)" (! sect. 5)
3. "Phrase structure rules (e.g., "X-bar theory" or "immediate dominance rules")" (! sect. 5)
4. "Rules of linear order" to distinguish, for example, subject from object, or "case affixes" which "can take over
these functions" (! sect. 5)
5. "Verb affixes" signaling "aspect" and "tense" (including pluperfects) (! sect. 2.2.3)
6. "Auxiliaries"
7. "Anaphoric elements" including pronouns and reflexives
8. "Wh-movement"
There are clear counterexamples to each of these claims. Problems with the first three are discussed in section
2.2.4 and section 5; here are counterexamples to the others:
(4) Some languages (e.g., Riau Indonesian) exhibit neither fixed word-order nor case-marking (Gil 2001).
(5) Many languages (e.g., Chinese, Malay) do not mark tense (Comrie 1985, pp. 50-55; Norman 1988, p. 163),
and many (e.g., spoken German) lack aspect (Comrie 1976, p. 8).
(6) Many languages lack auxiliaries (e.g., Kayardild, Bininj Gun-wok).
(7) Many languages (e.g. Mwotlap; Francois 2005, p. 119) lack dedicated reflexive or reciprocal constructions
altogether, so that "they hit them dead" can mean "they killed them," "they killed themselves," or "they killed
each other" (Levinson 2000, p. 334 ff.). Some Southeast Asian languages lack clear personal pronouns, using
titles (of the kind "honorable sir") instead, and many languages lack third-person pronouns (Cysouw 2001).
Sign languages like ASL (American Sign Language) also lack pronouns, using pointing instead.
(8) Not all languages (e.g., Chinese, Japanese, Lakhota) move their wh-forms, saying, in effect, "You came to see
who?" instead of "Who did you come to see _" (Van Valin & LaPolla 1997, pp. 424 -25).
Some further universalizing claims with counterevidence:
(9) Verbs for "give" always have three arguments (Gleitman 1990); Saliba is a counterexample (Margetts 2007).
(10) No recursion of case (Pinker & Bloom 1990). Kayardild has up to four layers (Evans 1995a; 1995c).
(11) No languages have nominal tense (Pinker & Bloom 1990) - Nordlinger and Sadler (2004) give numerous
counterexamples, such as Guarani "my house-FUTURE-FUTURE" "it will be my future house."
(12) All languages have numerals (Greenberg 1978b - Konstanz #527). See Everett (2005; Gordon 2004) for
counterexample.
(13) All languages have syntactic constituents, specifically NPs, whose semantic function is to express general-
ized quantifiers over the domain of discourse (Barwise & Cooper 1981 - Konstanz #1203); see Partee (1995)
and sect. 5.

Evans & Levinson: The myth of language universals
Box 2. The challenge of sign languages
Many proposed universals of language ignore the existence of sign languages - the languages of the deaf,
now recognized to be full-blown languages of independent origin (Klima & Bellugi 1979). Studies of, for
example, American Sign Language, British Sign Language, and Indo-Pakistani Sign Language (Zeshan 2002)
show that these are unrelated, complex systems of their own. They can even be said to have "phonologies" -
patterns of hand shape, facial expression, and so on, which, although individually meaningless, can be combined
to make morphemes or words (Padden & Perlmutter 1987).
The typology of sign languages is in its infancy (see, e.g., Perniss et al. 2008; Perniss & Zeshan 2008; Schwager
& Zeshan 2008; Zeshan 2006a; 2006b). The Ethnologue lists 121 sign languages, but there are certainly many
not yet listed. The major sign languages show some typological similarities, but the smaller ones, only now
coming under scrutiny, are typologically diverse (see, e.g., Meir et al., in press).
Sign languages offer a model "organism" for understanding the relation between biological and cultural
aspects of language (Aoki & Feldman 1994). They also offer unique opportunities to study the emergence of
new languages under different conditions: (a) where home-signers (Goldin-Meadow 2003) are congregated
and a sign language emerges among themselves, as in Nicaragua (Senghas et al. 2004); and (b) where a localized
hereditary deaf population lives among hearers who also sign, as in Bali (Marsaja 2008) or in a Bedouin group in
Israel (Sandler et al. 2005). These studies show that although word order constraints may show early, it may take
three generations or more to evolve syntactic embedding and morphology.
When due allowance is made for the manual-visual interface, sign languages seem to be handled
