Atkinson (2011) discusses a tantalizing result, that phoneme inventory size may reflect a set of population expansions out of Africa tens of thousands of years ago. The starting point for the article is a correlation, first noted in Hay & Bauer 2007, that inventory size is positively correlated with population size. Atkinson shows that inventory size, as measured by a combination of features based on WALS data (Haspelmath et al. (eds.) 2008), declines as distance from Africa increases, even…

Phoneme inventory size and the transition from monoplanar to dually patterned speech

Atkinson (2011) shows that phoneme inventories are largest in Africa and smaller elsewhere, and suggests that this clinal distribution reflects a serial founder effect of human migrations out of

PHONEME INVENTORY SIZE DISTRIBUTIONS AND THE ORIGINS OF THE DUALITY OF PATTERNING

Atkinson 2011 claims that phoneme inventories are largest in Africa and smaller elsewhere, and that this clinal distribution reflects a ‘founder-effect’ of human migrations ‘out-of-Africa’. Because

Can a linguistic serial founder effect originating in Africa explain the worldwide phonemic cline?

TLDR
A model that simulates the human range expansion out of Africa and the subsequent spatial linguistic dynamics until today agrees with the observed decrease of linguistic diversity with increasing distance from the most likely origin of the out-of-Africa dispersal.

A serial founder effect model of phonemic diversity based on phonemic loss in low-density populations

TLDR
The question of whether an alternative explanation for the worldwide phonemic cline is possible is tackled, by using alternative assumptions, and it is shown that this pattern may be due to a repeated bottleneck effect and phonemic loss.

Phonological Koinéization in Kathmandu Tibetan

This paper tests the new-dialect formation model of Peter Trudgill (1986 et seq) by examining several phonological features of Tibetan as spoken in the diaspora community of Kathmandu, Nepal.

Rejection of a serial founder effects model of genetic and linguistic coevolution

TLDR
It is shown that phoneme inventories provide information about recent contacts between languages, however, because phonemes change rapidly, they cannot providing information about more ancient evolutionary processes.

Dating the Origin of Language Using Phonemic Diversity

TLDR
This work uses a natural experiment, the colonization of Southeast Asia and Andaman Islands, to estimate the rate at which phonemic diversity increases through time, and estimates that present-day languages date back to the Middle Stone Age in Africa.

Response to Comment on “Phonemic Diversity Supports a Serial Founder Effect Model of Language Expansion from Africa”

Jaeger et al. use statistical simulations to show that the serial founder effect analysis I reported has an inflated type 1 error rate. Crucially, however, their simulations also reveal that the

A comparison of worldwide phonemic and genetic variation in human populations

TLDR
The results show that migration within geographic regions shapes phoneme evolution, although human expansion out of Africa has not left a strong signature on phonemes, and suggests that relatively isolated languages are more susceptible to phonemic change than languages with many neighbors.

Phonemic Diversity Supports a Serial Founder Effect Model of Language Expansion from Africa

TLDR
It is shown that the number of phonemes used in a global sample of 504 languages is also clinal and fits a serial founder–effect model of expansion from an inferred origin in Africa, pointing to parallel mechanisms shaping genetic and linguistic diversity and supports an African origin of modern human languages.

TLDR
It is argued that isolation is a multifaceted phenomenon with geographic, social and attitudinal implications and its potential for variation and change studies is discussed, both in terms of synchrony and diachrony.

Does Lateral Transmission Obscure Inheritance in Hunter-Gatherer Languages?

TLDR
The results debunk the myth of high borrowing in hunter-gatherer languages and suggest that the evolution of these languages is governed by the same type of rules as those operating in large-scale agriculturalist speech communities.
