Because Darwin. From Science Nordic: Both groups breed in the same area in the Caribbean, the Sargasso Sea, but typically you would expect a long-term physical separation of the two, to allow them to develop in different directions. This makes them a great mystery of evolution. Now scientists have solved this puzzle. It turns out […]

From ScienceDaily: The team studied a plant-eating stick insect species from California called Timema cristinae known for its cryptic camouflage that allows it to hide from hungry birds, said CU-Boulder Assistant Professor Samuel Flaxman. T. cristinae comes in several different types — one is green and blends in with the broad green leaves of a […]

Darwin’s finches, we are told, have reached their limits on the Galapagos Islands From ScienceDaily: The evolution of birds on the Galapagos Islands, the cradle of Darwin’s theory of evolution, is a two-speed process. Most bird species are still diversifying, while the famous Darwin’s finches have already reached an equilibrium, in which new species can […]

The local tax funded cult, it turns out, is safe. Here: Why Close Relatives Make Bad Neighbors Abstract The number of exotic plant species that have been introducedinto the United States far exceeds that of other groups of organisms, and many of these have become invasive. As in many regions of the globe, invasive members […]

Mainly about the history of intelligent design of dogs, for better or worse. Fascinating stuff about the turnspit dog. Also. here: In order to understand how a breed can go extinct, first we need to get into what a breed is. And in order to get into that, we need to get into what a […]

Speciation is not very well understood at all, anywhere; it is rather colonized by Darwin’s followers, as a support for their vision of life.

Some call these types of life forms “Lazarus species,” animals we thought were extinct. (One third apparently turn up again.)

Tom Bethell: But it doesn’t take a genius to see that the ancestral group is (improperly) defined by the absence of the character that defines the descendant group.

Dunno. Local grass snakes keep insisting that reptiles exist—as long as they can get below the frost line over winter, through cavities in the Shield.

Didn’t realize it was that uncertain. Were told it was happening very day in every way. 😉

Researchers: Parasitic ants were no longer reproductively compatible with the host ants — making them a unique species.

Until very recently, the lichen was believed to have just one species of fungus.

Maybe the world is so fuzzy below the level of the genus that another approach to classification should be sought (and why that won’t happen soon).

Don’t forget how much of the whole concept of a “species” is obscured and vitiated by the hunt for observed Darwinian speciation.

So why use the word “evolved” at all? So we can pretend to know stuff we don’t?

As David Tyler writes over at Access Research Network: Introgressive hybridization and the Galapagos finches A branching pattern of variation was central to Darwin’s concept of speciation. As one population of organisms follows one trajectory, another population may spin off in a different direction. When they are sufficiently far apart, they are considered to be […]

Character displacement is “one of the main Darwinian ideas for explaining why species are different”

In short, it is unclear, even in this fairly straightforward case, that Darwinian speciation has actually occurred. Circumstances have been spotted under which it might be occurring. Of course, some perturbation in the landscape might blow it all away.

Bird malaria has hit the Galapagos, and may affect Darwin’s finches. As it happened, Darwin contributed little to the study of finches beyond their name. In the context of a cathedral dedicated to him, that cannot of course be spelled out.
