A crucial design feature of language useful for determining when grammatical language evolved in the human lineage is our ability to combine meaningless units to form a new unit with meaning (combinatoriality) and to further combine these meaningful units into a larger unit with a novel meaning (compositionality). There is overlap between neural bases that underlie hierarchical cognitive functions required for compositionality in both linguistic and nonlinguistic contexts (e.g., tool use…

The evolution of combinatorial structure in language
The precedence of syntax in the rapid emergence of human language in evolution as defined by the integration hypothesis
TLDR
It is argued that a full-fledged combinatorial operation Merge triggered the integration of two pre-adapted systems, giving rise to a fully developed language, going against the gradualist view that language has undergone a series of gradual changes.
Compositionality in animals and humans
TLDR
Evidence that beneath the staggering complexity of human syntax, there is an extensive layer of nonproductive, nonhierarchical syntax that can be fruitfully compared to animal call combinations is reviewed.
STAGES OF CULTURAL ELABORATION IN THE PLEISTOCENE: POSSIBLE ARCHAEOLOGICAL INDICATORS OF THE DEVELOPMENT OF LANGUAGE CAPABILITIES
Asking an archaeologist to discuss language is rather like asking a mole to describe life in the treetops. The earthy materials with which archaeologists deal contain no direct traces of the
The minimalist grammar of action
TLDR
This study presents a biologically inspired generative grammar of action, which employs the structure-building operations and principles of Chomsky's Minimalist Programme as a reference model and shows, how the tool role and the affected-object role of an entity within an action drives the derivation of the action syntax in this grammar.
An earlier origin for stone tool making: implications for cognitive evolution and the transition to Homo
TLDR
The discovery of the earliest known stone tools at Lomekwi 3 (LOM3) from West Turkana, Kenya, dated to 3.3 Ma, raises new questions about the mode and tempo of key adaptations in the hominin lineage and forms part of an emerging paradigm shift in palaeoanthropology.
Culture: A Human Domain
It is argued that a number of recent writings based on primate studies and on analysis of early hominid evolution have blurred certain central issues regarding human and non-human primate behavior.
