The quagga and the woolly mammoth

Dear reader,

did you ever see a quagga or heard of them? Of course not seen it „for real“. They've been extinct since about 1883. Quaggas have been relatives of plain zebras today. Although the quagga wasn't white with black stripes, but light brown with almost no white stripes except on the head and neck. They have lived in South Africa and have been hunted mostly, because they were seen by the Dutch settlers as natural competitors of the cows. Only much later, after the last quagga had died August, 12, 1883 in the Artis-Zoo in Amsterdam, it was realised just how far the hunt had gone. By the way, the quagga (Equus quagga quagga) was not a separate species of zebras, but a subspecies of the plain zebra (equus quagga).

In 1987 The Quagga Project was started. The idea is pretty simple: when two plain zebras with few stripes mate, they (hopefully) get a child with few stripes and eventually the zebras of the project will then have so few stripes that they resemble the quagga. These could then be settled back in South Africa. So a mistake once made over 100 years ago would, at least in part, be put right. One could argue that a zebra, which looks like a quagga, because it has few stripes, doesn't make a real quagga. The people of the Quagga Project actually thought about that, too, and argue against that on the subpage Criticism of the Quagga Project. They say that because the quagga is extinct now, no other specifics other than the reduction of stripes can be made out. Also the grasses the plain zebras eat today are very close to those that existed in quagga times and would. So really it isn't a very strong argument to say that the reduction of stripes alone will not make a real quagga. You are free give your thoughts on that in the comments.

The Quagga Project has a whole bunch of photos with zebras, which already have visibly fewer stripes already. You can check out the photos at the following link: http://www.quaggaproject.org/Quagga-Graphic-Elements/PhotoGallery/PhotoGallery/slide.html

Woolly mammoths were pretty common in America as well as Eurasia before they went extinct. Because they have been living and gone extinct in a cold stage, many remains have been mummified because of the ice and remained relatively preserved. Maybe you can imagine what some scientists think of or are actually more or less working on. Correct, the mammoth would raise from the dead. Similarly to the quagga one attempt is get close to a mammoth through selection of existing elephants. Another thought is to use available DNA from mammoths and use them or even creating the necessary DNA, that is the sperm, to plant it into a living elephant. The cow elephant then would idially give birth to a mammoth baby. The anatomy of elephants and other aspects such as the suspected long gestation period like living elephants today (which is about 21 to 22 months) would make this very difficult and would make this a really long and time-consuming project. To create an artificial egg cell, the chromosome science isn't quite ready yet and the needed specimens of existing cells of mammoth findings are too fragmented.

I could sort of understand to create a quagga. This zebra-quagga would at least live Africa in an environment close to that of the actual quagga. A mammoth however... Where should the mammoth live and what from?

Surely it's an exciting thing, whether it can be possible to recreate animals again. But what for? To have again what isn't anymore and existed once before? To be able to say and show that we could and die make it happen? It would certainly be a sensation and impressive. But I think, it shouldn't be forgotten that the real natural environment of the animals doesn't exist anymore. The so called civilised humans will destroy the world more and more and with it the animals that (still) exist today. Wouldn't it make more sense, instead of recreating extinct animals, to make it so that endangered and critically endangered animals live can live on?

Until next blog,
sarah
