Genetic structure in Orkney island mice: isolation promotes morphological diversification
Following human occupation, the house mouse has colonised numerous islands, exposing the species to a wide variety of environments. Such a colonisation process, involving successive founder events and bottlenecks, may either promote random evolution or facilitate adaptation, making the relative importance of adaptive and stochastic processes in insular evolution difficult...Chevret, Pascale ; Hautier, Lionel ; Ganem, Guila ; Herman, Jeremy S ; Agret, Sylvie …

Genetic isolation of a now extinct population of bottlenose dolphins ( Tursiops truncatus )
A number of dolphin species, though highly mobile, show genetic structure among parapatric and sometimes sympatric populations. However, little is known about the temporal patterns of population structure for these species. Here, we apply Bayesian inference and data from ancient DNA to assess the structure and dynamics of bottlenose dolphin...Nichols, Courtney ; Herman, Jeremy S. ; Gaggiotti, Oscar E ; Dobney, Keith M ; Parsons, Kim …

Ancient genomes indicate population replacement in Early Neolithic Britain
The roles of migration, admixture and acculturation in the European transition to farming have been debated for over 100 years. Genome-wide ancient DNA studies indicate predominantly Aegean ancestry for continental Neolithic farmers, but also variable admixture with local Mesolithic hunter-gatherers. Neolithic cultures first appear in Britain circa 4000 bc, a millennium after...Brace, Selina ; Diekmann, Yoan ; Booth, Thomas J ; Faltyskova, Zuzana ; Rohland, Nadin …
