Our species displays remarkable linguistic diversity. Although the uneven distribution of this diversity demands explanation, the drivers of these patterns have not been conclusively determined. We address this issue in two steps: First, we review previous empirical studies whose authors have suggested environmental, geographical, and sociocultural drivers of linguistic diversification. However, contradictory results and methodological variation make it difficult to draw general conclusions… 
The ecological drivers of variation in global language diversity
While climate and landscape provide strong explanatory signal for variation in language diversity, a number of areas of high unexplained language diversity are identified, with more languages than would be predicted from environmental features alone; notably New Guinea, the Himalayan foothills, West Africa, and Mesoamerica.
Drivers of geographical patterns of North American language diversity
It is shown that the ecological drivers of language diversity are not universal or entirely direct, and the strongest associations imply a role for previously developed hypothesized drivers such as population density, resource diversity, and carrying capacity with group size limits.
Oceanic barriers promote language diversification in the Japanese Islands
The findings reported here are the first quantitative evidence that physical barriers formed by ocean can influence language diversification and points to an intriguing common mechanism between linguistic and biological evolution.
Evolution within a language: environmental differences contribute to divergence of dialect groups
Given that the dialects of isolated speaker populations may eventually evolve into different languages, the result suggests that cultural adaptation to local environment and the associated isolation of speaker populations have contributed to the emergence of the global patterns of linguistic diversity.
The geographical configuration of a language area influences linguistic diversity
Like the transfer of genetic variation through gene flow, language changes constantly as a result of its use in human interaction. Contact between speakers is most likely to happen when they are
The geography and development of language isolates

A simple model is developed for the genesis of isolates as a function of proximity to major geographical barriers, and pit it against an alternative view that sees them as one manifestation of linguistic diversity generally.
The evolution of language families is shaped by the environment beyond neutral drift
The phylogenetic signals of environmental factors and population size on more than 6,000 phylogenetic trees of 46 language families are estimated and find that environment influences the evolution of language families beyond neutral drift.
Rapoport's Rule Revisited: Geographical Distributions of Human Languages
The results point to group boundary formation as a critical mediator of the relationship between Rapoport's rule and diversity patterns, where strong group boundaries limit range overlap, and range sizes increase with latitude, latitudinal richness gradients may result.
Recent studies in language prehistory with special reference to South Asia
The idea that languages and genes have correlated evolutionary paths was observed at least since Darwin (1871). The recent advances in genetics and comparative linguistics have allowed researchers to


The distribution of cultural and biological diversity in Africa
One of the first quantitative descriptions of an apparent coincidence in species diversity and human cultural or linguistic diversity is presented and it is shown that, for 2° × 2° grid cells across sub–Saharan Africa, cultural diversity and vertebrate species diversity exhibit marked similarities in their overall distribution.
Political complexity predicts the spread of ethnolinguistic groups
It is argued that a process of cultural group selection favoring more complex societies may have been important in shaping the present-day global distribution of language diversity.
Linguistic diversity of the Americas can be reconciled with a recent colonization.

Stock diversity is highest in the Americas, which are by consensus the youngest continents, intermediate in Australia and New Guinea, and lowest in Africa and Eurasia where the time depth is greatest.
Evolved structure of language shows lineage-specific trends in word-order universals
These findings support the view that—at least with respect to word order—cultural evolution is the primary factor that determines linguistic structure, with the current state of a linguistic system shaping and constraining future states.
Language Diversity in West Africa: An Ecological Approach
Abstract Analysis of a linguistic atlas reveals an ecological gradient in the diversity of languages in West Africa. As one moves south from arid into lusher ecoclimatic zones, the average size of
Nothing has yet lasted forever: current and threatened levels of biological and cultural diversity
The analogy between biodiversity and cultural diversity cannot be general for all scales and areas, given the immense differences in history and various other factors, but the correspondence observed across and within species in these two groups is remarkable.
Co-occurrence of linguistic and biological diversity in biodiversity hotspots and high biodiversity wilderness areas
The results reported in this article provide a starting point for focused research exploring the relationship between biological and linguistic–cultural diversity, and for developing integrated strategies designed to conserve species and languages in regions rich in both.
The island biogeography of languages
Aim  To examine the degree to which area, isolation, environmental conditions and time since first settlement explain variation in language richness among islands. Location  Pacific islands
A parasite‐driven wedge: infectious diseases may explain language and other biodiversity
It is shown that the worldwide distribution of indigenous human language diversity is strongly, positively related to human parasite diversity indicative of a legacy of parasite-mediated diversification.
Language Phylogenies Reveal Expansion Pulses and Pauses in Pacific Settlement
The results are robust to assumptions about the rooting and calibration of the trees and demonstrate the combined power of linguistic scholarship, database technologies, and computational phylogenetic methods for resolving questions about human prehistory.
