Human language is a recombinant system that achieves its productivity through the combination of a limited set of sounds. Research investigating the evolutionary origin of this generative capacity has generally focused on the capacity of non-human animals to combine different types of discrete sounds to encode new meaning, with less emphasis on meaning-differentiating mechanisms achieved through potentially simpler temporal modifications within a sequence of repeated sounds. Here we show that… 
Internal acoustic structuring in pied babbler recruitment cries specifies the form of recruitment
Evidence is provided for internal “meaning-refining” acoustic variation within a larger stereotyped signal in pied babblers, lending support to the hypothesis that combinatorial structuring may have emerged in species with limited or fixed vocal repertoires in order to enhance communicative output.
Combinatoriality in the vocal systems of nonhuman animals.
An overview of the current evidence for combinatorial structures found in the vocal system of diverse species is provided and it is suggested that a fine-grained classification and differentiation of combinatorsiality is a useful approach permitting systematic comparisons across animals.
More than just babble: functional and structural complexity of vocalizations of Jungle Babbler
This study demonstrates that Jungle Babblers possess a structurally and functionally complex vocal repertoire, and lays the foundation for future investigations on combinatorial and syntactical rules underlying call function and structure in bird vocalizations.
Structural and functional complexity of vocalizations in a cooperatively breeding passerine, Jungle Babbler
This study examined complex communication in a cooperatively breeding social passerine, Jungle Babbler, for which it assessed repertoire size, function, acoustic features of calls and of their constituent elements and found that several calls were composed of multiple, acoustically distinct notes.
Communication as a Fundamental Part of Machiavellian Intelligence
It is shown how a focus on communicative and cognitive complexity together can elucidate nuanced manipulations for selfish gains in socially complex groups, under both competitive and cooperative scenarios.
Vocal production in postpartum dairy cows: Temporal organization and association with maternal and stress behaviors.
Calf separation was associated with a greater proportion of calls emitted as a sequence, a shorter interval between separate call sequences, and a greater number of vocal units per sequence, compared with calf interactions, and temporal vocal features varied predictably with the high stress expression from cows during calf separation.


Meaningful call combinations and compositional processing in the southern pied babbler
Evidence for rudimentary compositionality in the discrete vocal system of a social passerine, the pied babbler, is provided and indicates that the ability to combine and process meaningful vocal structures, a basic syntax, may be more widespread than previously thought.
Acoustic sequences in non‐human animals: a tutorial review and prospectus
A uniform, systematic, and comprehensive approach to studying sequences is proposed, with the goal of clarifying research terms used in different fields, and facilitating collaboration and comparative studies.
Experimental evidence for teaching in wild pied babblers
Learned kin recognition cues in a social bird
It is shown that cooperatively breeding long-tailed tits (Aegithalos caudatus) can discriminate between kin and non-kin according to the individual-specific characteristics of contact calls, and experimentally that individuals learn these calls from provisioning adults during the nestling period.
Language evolution: syntax before phonology?
A linguistically informed review of animal call sequences demonstrates that phonology in animal vocal systems is rare, whereas syntax is more widespread, and hypothesize that syntax, present in all languages, evolved before phonology.
Syllable acoustics, temporal patterns, and call composition vary with behavioral context in Mexican free-tailed bats.
Results indicate that syllable acoustics alone do not likely provide enough information for call recognition; rather, the acoustic context and temporal emission patterns of vocalizations may affect meaning.
