Morphological differentiation despite gene flow in an endangered grasshopper

Gene flow is traditionally considered a limitation to speciation because selection is required to counter the homogenising effect of allele exchange. Here we report on two sympatric short-horned grasshoppers species in the South Island of New Zealand; ... [Published 7thSpace - Oct 16 2014]

Quotes

...Dr Paul Ashton, Head of Biosciences, said: "The last lecture series proved a great success in outlining the work of the department and its wider application across biology. This year's series builds on that experience and will feature areas as diverse as the biological effects of chemical warfare, the treatment of acne, the role of fungi in biological processes and recent discoveries in the field of evolutionary processes."
...According to news reporting originating from Vancouver, Canada , by VerticalNews correspondents, research stated, "Migratory divides are contact zones between populations that use different routes to navigate around unsuitable areas on seasonal migration. Hybrids in divides have been predicted to employ intermediate and potentially inferior routes."
Jordan Haywood, principal engineer at Siemens Energy, explains the situation in the US: "Most environmental permits in the United States regulate on a time-averaged requirement, for example over a one-hour rolling average. When engines changed load a few times a day, these short increases in emissions during ramping had little impact, but if an engine changes load frequently, there is no time to average out the peak and there is a possibility that the engine will go out of emissions compliance. In this situation, the plant would have to stop changing load until it had run at stable load for long enough to average out the peak. The expectation is that plants will be changing load more frequently to support renewables."
Creationists harp on the "gaps in evolution”, reference the fossil record, irreducible complexity and such like whereas in reality we would expect to find gaps in the fossil record, and the bits of the record that aren't gaps match what evolution predicts, and we have no example of anything that is irreducibly complex. No, the eye and the bacterial flagellum are not – that myth has been debunked by experts."
