TL;DR: This study analyses a global data set of killer whale genomes in a rare attempt to elucidate global population structure in a nonhuman species and underpins that episodic gene flow is ubiquitous in natural populations, and can occur across great distances and after substantial periods of isolation between populations.

TL;DR: A large and ethnically well defined Mandenka sample from Senegal is analysed for 80 nuclear DNA RFLPs, and compared with eight previously studied human populations, suggesting that geography does also affect long range population genetic relationships and is an important factor behind differentiation among human populations.

TL;DR: It is demonstrated that in the population described, differences in throat colour and breeding have been stable over a decade, but in contrast to North American benthic and limnetic stickleback species, these mating trait differences are not accompanied by divergence in morphology related to feeding, predator defence or swimming performance.

TL;DR: This work uses individual-based simulations and analytical modeling to compare the impact of range expansions and range shifts on genetic diversity and fitness loss, as well as the ability to recover fitness after either a shift or expansion.

TL;DR: The results confirm that archaic introgression has facilitated local adaptation, especially in immunity-related and metabolic functions and highlight its involvement in a coordinated response to pathogens out of Africa.
