Organism of the Day: Aurochs!

Behold, the Aurochs (Bos primigenius)!

Daww, it’s so small and cute!

 

It’s…a cow. I know. BUT! It is not just any mere cow. For lo, it is the ancestor to all domestic cattle. These were organisms not to be trifled with. The Aurochs is a creature that shared the land with humans in Europe and Asia for may thousands of years. It was a large beast, and yet largely swift and agile. That, matched with it’s fiery temper, made for a terrifyingly deadly combination. It makes one wonder why our ancestors decided to try to domesticate these things at all! The Aurochs were spread far and wide, and had 3 distinct subspecies, shown here with their distributions.

The Aurochs was a forest dwelling bovine, with a diet that consisted of grass and leaves from trees. They played a pivotal role in the ecosystem of many of Europe’s forests, acting as the top-teir herbivores. Their absence has led to the forests falling out of balance, an issue that’s still being delt with today. So, how long has our species known these animals? Here’s a hint:

And you thought hammer pants were ancient.

The bulls on all the cave paintings we’ve found, like this one from Lascaux, France from 17,000 years ago, are all aurochs. They certainly do have a lot of meat on them, and were probably very enticing for our ancestors. Probably less enticing was their ability to hunt you down without tiring if you pissed them off. How do we know so much about this extinct species? Well, they haven’t been long gone. The last Aurochs died in Poland in the 1600’s. There’s plenty of historical data about them. When he wasn’t busy bringing down the wrath of Mars on the Gauls, even Julius Caesar wrote about them,

…those animals which are called uri. These are a little below the elephant in size, and of the appearance, color, and shape of a bull. Their strength and speed are extraordinary; they spare neither man nor wild beast which they have espied. These the Germans take with much pains in pits and kill them. The young men harden themselves with this exercise, and practice themselves in this sort of hunting, and those who have slain the greatest number of them, having produced the horns in public, to serve as evidence, receive great praise. But not even when taken very young can they be rendered familiar to men and tamed.

Here’s an example of an extremely lucky man from the middle ages.

And a less fortunate Aurochs

So, why bring these creatures up? Because we’re bringing them back. The forests of Europe quite simply aren’t the same with out them, in a similar way Yellowstone National Park wasn’t the same without its keystone species, wolves. Beech trees are over-running the forests without the massive bovines. The TaurOs and Uruz Projects are using selective breeding to bring back a breed of cattle that can replace the aurochs and be very genetically similar. And they’re getting closer.

Organism of the Day: Thor’s Hero Shrew

Ah, the Adorable, yet mighty Thor’s Hero Shrew (Scutisorex thori)!

thors-hero-shrew

These little guys were discovered recently. They are not a new genus, although they are awesome nonetheless. Hero Shrews are from Africa, in the Democratic Republic of the Congo. The people living there, the Mangbetu, already had named these creatures Hero Shrews along way back. Why? Because the thing is practically indestructible. Simply put, Hero Shrews (Thor’s being the newest discovery) have spines where the lumbar vertebrae interlock (8 in Thor’s, 11 in the first described species, the African Hero Shrew S. somereni). They can have an enormous amount of weight on their backs, and emerge unscathed. The Mangbetu people display this by stepping on a shrew with a single leg for several minutes, and when they step off, the shrew runs away. Why they have spines of steel is unknown, but it has been hypothesized that they use it as a brace to push up heavy pieces of palm trees to access the nutrient rich grubs that live in them. They have the strongest spine of any mammal. Note: the first spine is of a typical shrew, the other 2 (b and c) belong to Hero Shrews, with the last being Thor’s Hero Shrew.
