Mayr was well known for his championship of the biological species concept and for asserting a predominant role for the geographic separation of populations in the diversification process that gives ...

Speciation is the process by which new species forms and is the driving force of biodiversity. Since Darwin published On the Origin of Species, great efforts have been performed without interruption ...

Reminiscence of the early days / Wendell L. Roelofs -- Pheromones : reproductive isolation and evolution in moths / Jeremy D. Allison and Ring T. Cardé -- Variation in moth pheromones : causes and ...

Female giant water bugs lay their eggs on a male's back after mating and the male takes care of the eggs until the nymphs are hatched, a couple of weeks later. A study led by Dr. Tomoya Suzuki of ...

Reproductive isolation is a biological process that prevents gene flow between populations or species, thereby maintaining or promoting genetic divergence and speciation. It operates through ...

Understanding the relative importance of reproductive isolating mechanisms across the speciation continuum remains an outstanding challenge in evolutionary biology. Here, we examine a common isolating ...

Hendry's team observed that male river sockeyes are slimmer than their lake counterparts (to better deal with the river's strong current), while the female river sockeye are larger than their beach ...
