	abstract = {<p>The present paper provides an integrative theory of actions and motor programs for skill in tool use, construction, and language. We analyze preconditions for action as well as making their effects (postconditions) explicit, emphasizing the {\textquotedblleft}how{\textquotedblright} of action details as well as the {\textquotedblleft}what{\textquotedblright} of motor programs, aided by conceptual analysis of several brain modeling efforts. The theory is exemplified by analysis of the subtractive construction involved in percussive tooling by capuchin monkeys and Oldowan and Acheulean stone tool making by protohumans before turning to the additive construction of hafted tools. A complementary analysis focused on the construction of bird nests explores the notion of {\textquotedblleft}image{\textquotedblright} and {\textquotedblleft}stage{\textquotedblright} in construction. We offer a brief comparison with birdsong before arguing for a very different relation between communication and construction in humans. Pantomime lifts manipulation from practical to communicative action in protohumans, and we consider the role of pedagogy before offering hypotheses on the emergence of human language that suggest how language may have evolved from manual skills. We note that language provides an open-ended means for devising innovations in tool use and construction, but reiterate the importance of this framework for diverse future studies in ethology and comparative psychology.</p>
