The historical impact of Archaeopteryx

Believe it or not, I’m trying to cut down on the Archaeopteryx posts but well, it is a big anniversary and it is such a very cool animal with many interesting and important facets to it’s scientific life that I don’t seem to be able to stop. One thing that really should get a mention is the small role it played it buoying up Darwin’s theory of natural selection.

Perhaps unsurprisingly the initial publication of the Origin lead to rather  mixed reviews. While it did have a number of important and influential supporters, it also inevitably came in for some really strong criticism. Darwin has quite rightly noted a number of major problems with his own work and there were certainly some gaps that needed to be filled sooner or later. One of these (which is of course still ludicrously trumpeted by the creationists) was the apparent lack of transitional fossils. If Darwin was right and birds and mammals had come from reptiles, amphibians from fish and so one, then where were all those in-betweens?

The obvious short answer is that 150 years ago the fossil record had only just begun to be explored. We didn’t have many dinosaurs yet (which were nice and big and preserved in big numbers in well explored countries like the US and Belgium) let alone all manner of well, just about everything. Palaeontology as a field was only just getting going and there were very few researchers doing relatively little research and they’d not done much. We now of course have enormously detailed and complete transitional series for the origins of whales and amphibians and vertebrates and all kinds of others. We do of course also know a great deal about the origin of birds, but in addition to its important phylogenetic position, Archaeopteryx very publicly plugged one of those big gaps.

Coming to light a just a couple of years after the publication of the Origin, it was a clear and obvious fillup for Darwin and vindication of his ideas. Here was something that was obviously a bird (it had feathers) but obviously not quite a bird (it had teeth and a long tail and clawed fingers). It was part bird and part reptile -  a halfway house. Darwin obviously recognised the fact and it must have been enormously gratifying to see something like this turn up. In a letter to a colleague in 1893 he wrote:

“The fossil Bird with the long tail & fingers to its wings is by far the greatest prodigy of recent times. It is a grand case for me; as no group was so isolated as Birds; & it shows how little we know what lived during former times.”

And he also took a letter from another colleague that same year that clearly referenced this fact as well:

““You were never more missed—at any rate by me—for there has been this grand Darwinian case of the Archaeopteryx for you and me to have a long jaw about”.

Darwin was therefore well aware of just what Archaeopteryx could do for his ideas and as he notes, the birds had seemed an especially disparate group compared to other vertebrates yet here was an obvious transition, or at least possible connection, between birds and reptiles. Perhaps more importantly, this obviously was recognised by his colleagues as well and provided a strong case that the fossil record had much more to say about the theory of evolution and that what it would say might well support Darwin. The timing was really quite perfect then.

Thanks to Rich Tabor and Brian Switek for helping me track down those quotes.

Great biologists

If you are sick of posts based around the exhibits and displays of Oxford then I am afraid there are still a few more to go. However, my visit provided me with so much good material for posts with dinosaurs, pterosaurs, models, art and historical stuff that this was all but inescapable. I am starting to run out though, but in the meantime it would be a shame to let this go past.

Modern museums understandably tend to emphasise the specimens on display and the conveyance of information about them. Nothing wrong with this in any way at all I hasten to add, but there is something about the grandeur of classic museums that tends to be lacking. Partly that comes from the architecture – no matter how awesome the Fukui dinosaur museum is as a building (it’s a 100 m [ish]) silver dome) it’s not really the Natural History Museum in London either. Some of that quite indescribable and ephemeral feeling can however certainly be captured by things like this -marble statues of great biologists and scientists through the ages.

Here of course the emphasis is on zoology and palaeontology with Buckland (above) and Darwin and Hunter (below) featuring and other such as Aristotle and Cuvier (as I recall) also being present. Little to do with a traditional display admit, but it’s hard not to appreciate them for their aesthetics alone, in addition to their contribution of celebrating the work of such important people.

Darwin in Beijing

imgp1674Charles Darwin of course never made it to China on his very extensive travels, but inevitably this year, and indeed on this day, he has a presence at the IVPP. I mentioned briefly before about a planned exhibition that has gone through with typical Chinese speed (in the end it was too short notice to include English notes for the admittedly few foreign visitors to the galleries, so I barely did anything for this) and was unveiled this morning.

It’s mostly a series of panels covering Darwin’s life and works and showing how modern evidence (most notably fossils in the IVPP of course) supports the theory of evolution by natural selection. As I say, it’s in Chinese, so few of my readers are likely to get much from it, but I took a couple of quick photos to show off a few of the panels, and especially the nice world map that shows the voyage of the Beagle and key events or finds from the journey. (Sorry about the odd angles of some of the photos it was necessary to avoid the gallery lights reflecting).

Three great protagonists, but probably not as they saw themselves

It’s good to see so many museums and institutes using this year as an excuse or motivation to get across some of the inspiring ideas and works of Darwin, and what has followed, plus to dispel a few of the worse and more perpetuated fictions. My only complaint would be that while an opportunity like this is too good to miss, (and certainly more funds and interest would be available than in other years) it is just a shame that something like this is needed to trigger it.

imgp16581While many museums have exhibits or even whole galleries on evolution, many small and even large ones do not even mention it. Surely something this fundamental to a natural history / science museum (and this goes for botanical gardens, aquaria and zoos as well) needs to be featured, and prominently at that? I honestly can’t think of a non-permanent exhibit to Darwin or evolution as a whole that I have ever seen in any museum (though as ever I may have just missed them). Many do have them, great, but for those that don’t, to have to wait for such an anniversary seems a bit silly to say the least.

Still, the work is being done and the word is being spread. For this we must be grateful, and I am certainly pleased that the IVPP are doing their part.
