re: “This isolated urban population of crustaceans is giving clear signs of having taken its own evolutionary course,” said Danilo Mainardi, a professor of behavioural ecology at Venice university.--------Zoologists say the new crab colony in the heart of Rome could turn out to be important for the conservation of the species, which risks dying out in rural waterways....

I guess a non-evo like me is about the only person to notice the contradiction here.

First, they claim to see the arrival of a new species. Then the praise the circumstances that appear to preserve a species unchanged.

No they didn't. No mention of new species was ever made. What the researchers were referring to was genetic isolation, which is one of the first steps toward speciation.

Then the praise the circumstances that appear to preserve a species unchanged.

No. They just said the colony in Rome could be important for the conservation of the species. They may have meant that by drawing attention to the crabs the government might take steps to keep the rural populations from dying out too. That's how I read the quote when I first saw it.
