The Economist: Hybrids have “upturned” evolutionary theory

At The Economist: “These findings muddy Darwin’s concept of speciation as a slow and gradual process. Biologists now know that in the right circumstances, and with the help of hybridisation, new species can emerge and consolidate themselves in a mere handful of generations. That is an important amendment to evolutionary theory. “

(Reformed) New Scientist 8: Evolution can happen very quickly

Does anyone remember Darwin’s claim: “It may be said that natural selection is daily and hourly scrutinizing, throughout the world, every variation, even the slightest; rejecting that which is bad, preserving and adding up all that is good; silently and insensibly working, wherever and whenever opportunity offers, at the improvement of each organic being in relation to its organic and inorganic conditions of life.” Yes, that “daily, hourly” thing seems quaint to us too. It probably even seems quaint over at New Scientist, given the stuff they’re saying now.

Paper: Paradigm shift needed in understanding evolution of complex animals

Paper: “Horizontal gene transfer and mating between diverged lineages blur species boundaries and challenge the reconstruction of evolutionary histories of species and their genomes.”
A friend writes to ask, “If we don’t have common descent, and we don’t have natural selection, why do we still call it evolution?”

“Astounding”hybridization between species of angelfish

At Phys.org: Other hybrids were found between species with over 12 percent pairwise distance in mitochondrial DNA. Pairwise distance is a measurement of differences in pairs of DNA sequences. “This genetic separation is quite astounding, considering that hybrids are rarely reported between species that share more than 2 percent in genetic distance,” Mr Tea said. “Though coral reef fish hybrids are common; they are usually formed by closely-related species.”

Darwinism is dead and the butterflies did it

No, but seriously, if “‘species’ are simply not what we thought they were,” as the researchers’ media release reads, all those carefully thought-out explanations of the neo-Darwinian origin of various butterfly traits must compete with “a complete morass of inter-connectedness.” Darwinism is dying and people are wisely refraining from spelling that out.

Claim: Hybridization “boosts evolution” in cichlids

From ScienceDaily: Animals that have either migrated to or been introduced in Central Europe — such as the Asian bush mosquito or the Asian ladybeetle — feel extremely comfortable in their new homes due to changing climatic conditions. If these newcomers are genetically compatible with local species, they may crossbreed and produce hybrids, which can Read More…
