On January
7, 2017, I posted a column titled Cave
Art Provides A Confirmation Of A Hybrid Bison Species In Paleolithic Europe,
which presented the use of cave art to confirm
a theory about the evolutionary development of the European bison which had
been based upon genetic analysis of ancient remains. Previously, on December 4,
2011, I had posted a column titled Lascaux's
Paintings, the Aurochs, and Heck's Cattle, about attempts in the middle of
the last century to breed cattle back to their Paleolithic form, the Aurochs.
These Heck's Cattle were produced using traditional methods of selecting for
traits and crossbreeding. Each generation being selectively bred for appearance
and behavior that was assumed to be similar to the Aurochs. These attempts were
begun in Germany in the 1920s by two brothers with the name of Heck. They were
later supported by the Nazi party in Germany. A lineage of cattle was bred by
each brother, one in Berlin and one in Munich. The Berlin animals did not
survive the war so modern Heck cattle are descended from the Munich line.

"The
aurochs was one of the largest herbivores in
postglacial Europe, comparable to the wisent (European bison). The size of an
aurochs appears to have varied by region; in Europe, northern populations were
bigger on average than those from the south. For example, during the Holocene,
aurochs from Denmark and Germany had
an average height at the shoulders of 155–180 cm (61–71 in) in bulls
and 135–155 cm (53–61 in) in cows, while aurochs populations in
Hungary had bulls reaching 155–160 cm (61–63 in). The
body mass of aurochs appears to have shown some variability. Some individuals
were comparable in weight to the wisent and the banteng, reaching around
700 kg (1,500 lb), whereas those from the late-middle Pleistocene are
estimated to have weighed up to 1,500 kg (3,300 lb), as much as the
largest gaur (the
largest extant bovid). The sexual dimorphism between bulls and cows was expressed with the cows
being significantly shorter than bulls on average." (Wikipedia)

A number of
programs in Europe are now undertaking to breed a new aurochs, not through
traditional breeding practices exemplified by the Heck's Cattle, but by using
genetic analysis to locate genes similar to the aurochs in modern breeds and
recombine them, in a sense to breed back to future of the aurochs.

Arden Dier,
writing for www.newser.com, on January 10, 2017, wrote: "Standing nearly as tall as an elephant, the aurochs grazed for
250,000 years until its extinction in
1627. But its story may not end there: Scientists say they are close to
resurrecting the "supercow," once the largest land mammal in Europe,
reports CNN. In search of herbivores to maintain land areas at risk of becoming
barren, geneticists began breeding aurochs descendant with similar cattle
breeds in 2008 and found they could "produce animals far closer to the
aurochs than we would have expected," says Ronald Goderie of the Tauros
Project. Fourth-generation beasts have now been introduced in Croatia, Spain,
Portugal, the Czech Republic, and Romania with promising results.
"We see progress not only in
looks and behavior but also in de-domestication of the animals," says
Goderie, noting one herd has learned to defend itself against wolves. The hope
is that they will become part of the ecosystem to maintain land for other
enimals. But a rep for the International Union for the Conservation of Nature
says it's unclear "whether primarily wetland forests like the aurochs used
to inhabit still exist, whether it could negatively impact wild or domestic
plants or animals, and if it might endanger people." Indeed, a British
farmer had to kill some of his aurochs-descended cattle in 2015 because they
tried to kill him, per the Independent. That species, however, came from a Nazi
breeding program that used Spanish fighting cattle." (www.newser.com)
Once again
we look at the possibility of being able to see the mighty creatures that our
ancient ancestors lived among and that they recorded in the beautiful heritage of
Paleolithic cave art. Definitely an exciting possibility (you can read the
original story at www.newser.com, check the full address in References below.)
