Adaptation and diversification on islands
TL;DR: Charles Darwin's travels on HMS Beagle taught him that islands are an important source of evidence for evolution, and island research provides valuable insights into speciation and adaptive radiation, and into the relative importance of contingency and determinism in evolutionary diversification.

Abstract: Charles Darwin's travels on HMS Beagle taught him that islands are an important source of evidence for evolution. Because many islands are young and have relatively few species, evolutionary adaptation and species proliferation are obvious and easy to study. In addition, the geographical isolation of many islands has allowed evolution to take its own course, free of influence from other areas, resulting in unusual faunas and floras, often unlike those found anywhere else. For these reasons, island research provides valuable insights into speciation and adaptive radiation, and into the relative importance of contingency and determinism in evolutionary diversification.

The Tortoise and the Finch: Testing for island effects on diversification using two iconic Galápagos radiations
TL;DR: This work addressed two general questions from a macroevolutionary perspective, do lineages on islands have increased diversification rates relative to mainland lineages, and does the same geographical context have similar effects on diversification in unrelated groups?

Echoes of the whispering land: interacting roles of vicariance and selection in shaping the evolutionary divergence of two Calceolaria (Calceolariaceae) species from Patagonia and Malvinas/Falkland Islands

TL;DR: This study indicates that glacial fluctuations affected the mainland/islands connections favouring speciation mediated not only by isolation, but also by climatic niche differentiation.

RAD-sequencing reveals patterns of diversification and hybridization, and the accumulation of reproductive isolation in a clade of partially sympatric, tropical island trees.

TL;DR: It is found that Mascarene Diospyros species diverged millions of years ago and are largely genetically distinct from one another, and hybridization was observed between closely related species belonging to the same subclade, but more distantly related species showed little evidence of interspecific hybridization.

TL;DR: The authors investigated the contribution of these processes to the global radiation of crows and ravens (genus Corvus) by combining a new phylogeny with comprehensive phenotypic and climatic data.
