Only prehistoric creatures would do, ones untainted by racial mixing, and although Lutz hoped to gain influence and fame in the process, his motives were more personalhe sought the thrill of bringing extinct, nearly magical animals back to life and steering their fate, hunting some for sport. Genetic engineering wouldnt emerge until the 1970s, but he decided to use eugenics, a traditional method of breeding animals which showed specific traits. Hecks reasoning went like this: an animal inherits 50 percent of its genes from each parent, and even an extinct animals genes remain in the living gene pool, so if he concentrated the genes by breeding together animals that most resembled an extinct one, in time he would arrive at their purebred ancestor. The war gave him the excuse to loot east European zoos and wilds for the best specimens.
As it happens, the animals he chose all thrived in Poland, their historic landscape was Bial/owiezÿa, and the imprimatur of a respected Polish zoo would legitimize his efforts. When Germany invaded Poland, Heck scouted the farms for mares preserving the most tarpan traits to mate them with several wild strains, including Shetlands, Arabians, and Przywalskis, hoping to breed back to the ideal animal, the fierce, nearly unridable horses painted in ochre on Cro-Magnon caves. Heck assumed it wouldnt take many generations of back-breedingmaybe only six or eightbecause as recently as the 1700s tarpans still roamed the forests of northeastern Poland.
During the Ice Ages, when glaciers blanketed northern Europe and a wind-ripped tundra stretched down to the Mediterranean countryside, thick forests and fertile meadows gave refuge to great herds of tarpans that roamed the central European lowlands, browsed the east European steppes, and galloped across Asia and the Americas. In the fifth century b.c., Herodotus said how much he enjoyed watching herds of tarpans grazing in the bogs and marshes of what is now Poland. For ages, purebred tarpans outwitted all the hunters and somehow survived in Europe, but by the eighteenth century not many remained, in part because diners prized tarpan meatit was sweet, but more appealingly, it was rareand in part because most tarpans had interbred with farm horses to produce fertile offspring. In 1880, pursued by humans, the last wild tarpan mare fell down a crevasse in Ukraine and died; and the last captive tarpan died seven years later in the Munich Zoo. At that point the species officially became extinct, just one more chapter in the annals of life on Earth.
Humans domesticated wild horses about six thousand years ago, and immediately began refining them: killing the defiant ones for food while breeding the most genial, to produce a horse that submits more easily to saddle and plow. In the process, we revised the horse s nature, compelling it to shed its zesty, ungovernable, evasive wildness. The aloof, free-range Przywalski horses retained that fury, and Heck planned to weave their combative spirit into the new tarpans genetic mix. History credits Colonel Nikolai Przywalski, a Russian explorer of Polish descent, with "discovering" the wild Asiatic horse in 1879, hence its name, though, of course, the horse was well known to the Mongolians, who had already named it tahki. Heck factored the tahkis stamina, temper, and looks into his formula, but he craved even older creaturesthe horses that dominated the prehistoric world.
What a powerful idealthat sexy, high-strung horse, pawing the ground in defiance, its hooves all declaratives. Heinz Heck wrote after the war that he and his brother had begun the back-breeding project out of curiosity, but also from "the thought that if man cannot be halted in his mad destruction of himself and other creatures, it is at least a consolation if some of those kinds of animals he has already exterminated can be brought back to life again." But why have tarpans to ride if there were nothing worthy to hunt?
