Stabilizing Forces In Acoustic Cultural Evolution: Comparing Humans And Birds, Daniel C. Mann

Dissertations, Theses, and Capstone Projects

Learned acoustic communication systems, like birdsong and spoken human language, can be described from two seemingly contradictory perspectives. On one hand, learned acoustic communication systems can be remarkably consistent. Substantive and descriptive generalizations can be made which hold for a majority of populations within a species. On the other hand, learned acoustic communication systems are often highly variable. The degree of variation is often so great that few, if any, substantive generalizations hold for all populations in a species.

Within my dissertation, I explore the interplay of variation and uniformity in three vocal learning species: budgerigars (Melopsittacus undulatus), …

A Cultural Diffusion Model For The Rise And Fall Of Programming Languages, Sergi Valverde, Ricard V. Solé

Human Biology Open Access Pre-Prints

Our interaction with complex computing machines is mediated by programming languages (PLs) which constitute one of the major innovations in the evolution of technology. PLs allowed a flexible, scalable and fast use of hardware and are largely responsible for shaping the history of information technology since the rise of computers in the 1950s. The rapid growth and impact of computers was followed closely by the development of programming languages. As it occurs with natural, human languages, they emerged and got extinct. There has been always a diversity of coexisting PLs that somewhat compete among them, while occupying special niches. Here …
