She's beautiful and interesting and important, but I do have to take exception to the surprisingly frantic news coverage I'm seeing. She's being called the "missing link in human evolution", which is annoying. The whole "missing link" category is a bit of journalistic trumpery: almost every fossil could be called a link, and it feeds the simplistic notion that there could be a single definitive bridge between ancient and modern species. There isn't: there is the slow shift of whole populations which can branch and diverge. It's also inappropriate to tag this discovery to human evolution. She's 47 million years old; she's also a missing link in chimp evolution, or rhesus monkey evolution. She's got wider significance than just her relationship to our narrow line.
People have been using remarkable hyperbole when discussing Darwinius. She's going to affect paleontology "like an asteroid falling down to earth"; she's the "Mona Lisa" of fossils; she answers all of Darwin's questions about transitional fossils; she's "something that the world has never seen before"; "a revolutionary scientific find that will change everything". Well, OK. I was impressed enough that I immediately made Ida my desktop wallpaper, so I'm not trying to diminish the importance of the find. But let's not forget that there are lots of transitional forms found all the time. She's unique as a representative of a new species, but she isn't at all unique as a representative of the complex history of life on earth.
... The hype is bad news, not because Ida is unimportant, but because it detracts from the larger body of the fossil record — I doubt that the media will be able to muster as much excitement from whatever new fossil gets published in Nature or Science next week, no matter how significant it may be.
Go ahead and be excited by this find, I know I am. Just remember to be excited tomorrow and the day after and the day after that, because this is perfectly normal science, and it will go on.
