At New Scientist: Questioning the idea of species

It’s good news that they are thinking this way. If we’re going to vote money and legislation for environmental protection, we do need useful working classifications. Why waste time, money and energy “saving” a “species” that doesn’t really exist as a separate entity when some whole ecologies are critically endangered? And it doesn’t matter how we choose to classify the “species” within them. At least these are more constructive discussions to be involved in than attacking or defending Darwinism.

(Reformed) New Scientist 12: Evolution favors some outcomes, not others

So “Each lake contains many different species that show striking similarities in the variety of body shapes to species in the other lake, despite being more closely related to those living in their own lake” but “These body shapes adapt species to particular niches or diets, so must have evolved by natural selection.” But wait! The traditional argument for natural selection acting on random mutations (Darwinism) was that the species WOULD BE similar to more closely related species. If they’re not, …

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. “

Hybrid pet cat bred from species as different as humans and chimpanzees

Or so they say. Working on a story about unusual facts about cats, I (O’Leary for News) came across an interesting piece of information from a NOVA documentary: CARLOS DRISCOLL: All domestic cats, up until the last 20 years, have been purely Felis silvesteris. Humans have, very interestingly, now hybridized the domestic cat with a Read More…

“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.”
