A new paper confidently claims that there are four giraffe species rather than one, but I’m not so sure

The giraffe, Giraffa cameleopardalis, was first described by Linnaeus, and gets its species name from its fancied resemblance to a hybrid beast (as notes, the name comes from the Greek καμηλοπάρδαλις” meaning “giraffe”, from “κάμηλος” (kamēlos), “camel” + “πάρδαλις” (pardalis), “leopard”, due to its having a long neck like a camel and spots like a leopard). It’s always been considered a single species, but divided into about a half dozen subspecies that live in different areas and are distinguishable by different patterns of reticulation in their coats. Here’s an old subspecies designation and map; note that the populations included in each of the six subspecies live in different areas:

Here’s a classification of nine subspecies based on pattern (the number of named subspecies has been between four and about nine (I haven’t searched extensively).

Note that this classification is more or less arbitrary because the populations are geographically isolated and so one can’t use the classical “biological species definition” (BSC), in which members of the same species are able to interbreed in nature and produce fertile hybrids, while members of different species, when present in the same area, either do not mate with each other, or, if they do mate, do not produce hybrids that are fertile. Note that to use the BSC, putatively different (or identical) species have to be “tested” when living in the same area (“sympatric”).If they do not encounter each other in nature, there’s little you can do to apply the BSC.

One way around this is to hybridize them in zoos. If different “subspecies” do not mate with each other, or can’t produce fertile hybrids when they do mate in captivity, they’re almost certainly unlikely to do so in nature, and can be considered members of different species. However, if two different types do hybridize and produce fertile offspring in captivity, that doesn’t mean they’re members of the same species, for in nature other “isolating barriers”, like different breeding times or a genetically-based aversion for mating with other types, could keep them genetically separated even though barriers could break down in the artificial environment of zoos.

What is race?

Yes, I would imagine his doctors gave him the go ahead to travel.

looks like Richard Dawkins has much improved from his light stroke. That's good to hear.

From Fins Into Hands: Scientists Discover a Deep Evolutionary Link

To help his readers fathom evolution, Charles Darwin asked them to consider their own hands.

“What can be more curious,” he asked, “than that the hand of a man, formed for grasping, that of a mole for digging, the leg of the horse, the paddle of the porpoise, and the wing of the bat, should all be constructed on the same pattern, and should include similar bones, in the same relative positions?”

Darwin had a straightforward explanation: People, moles, horses, porpoises and bats all shared a common ancestor that grew limbs with digits. Its descendants evolved different kinds of limbs adapted for different tasks. But they never lost the anatomical similarities that revealed their kinship.

As a Victorian naturalist, Darwin was limited in the similarities he could find. The most sophisticated equipment he could use for the task was a crude microscope. Today, scientists are carrying on his work with new biological tools. They are uncovering deep similarities that have been overlooked until now.

On Wednesday, a team of researchers at the University of Chicago reported that our hands share a deep evolutionary connection not only to bat wings or horse hooves, but also to fish fins.
