A German Hunter Killed One of Africa’s Biggest Elephants

Conservation groups in Zimbabwe aim to find the identity of the hunter to give him the ‘Cecil the lion’ treatment.

A German trophy hunter reportedly shot and killed one of the largest elephants recorded in nearly 30 years, and now a Zimbabwean conservation group wants to make him infamous, like the killer of Cecil the lion.

The 40- to 60-year-old elephant was shot just outside Zimbabwe’s Gonarezhou National Park and had tusks weighing more than 100 pounds each, Zimbabwe Conservation Task Force chairperson Johnny Rodrigues said in a statement.

“His tusks were so big that they dragged along the ground when he was walking,” Rodrigues said. This elephant was unknown to wildlife rangers at the park and might have wandered across the border from South Africa into Zimbabwe, where the unidentified hunter shot and killed it.

According to The Telegraph, the hunting organization that led the guided hunt has refused to name the hunter, who paid $61,000 to participate in a 21-day excursion that ended Oct. 8 with one dead elephant. But Rodrigues said the conservation group is going to find out the hunter’s identity.

“The authorities and the hunters’ association are trying to protect him, but we’ve got his photograph,” Rodrigues told The Guardian.

  In light of this egregious killing of one of Africa’s largest elephants, by a German trophy hunter,  it seemed fitting to repost a piece I did back in 2012 that examines how hunting may be altering and weakening species. Hunters with “tiny ego’s” have a penchant for killing the biggest and fittest animals, leaving smaller, weaker animals to breed.  A form of reverse evolution.

June 26, 2012

It turns out hunting animals may be more harmful than we thought,  especially trophy hunting.  It could be causing a kind of backward evolution, because the largest and most impressive animals, “prized” by hunters, are diminishing in some species, leading to a reduction in  size and other disturbing changes in the remaining animals.  In other words, the more robust members of certain species are disappearing, not by the process of “natural selection” but by hunting pressure. It’s as if hunters are selectively breeding animals in the wild by killing off the “trophy” animals, leaving the smaller and weaker individuals to breed.

Big horned sheep rams in Alberta, Canada have experienced a 25% decrease in horn size over the last thirty years. Being larger, with huge horns makes them a target for trophy hunters. It then follows the smaller sheep with less impressive horns, have more mating chances.

“Hunters frequently compare their role in the ecosystem to that of natural predators, some of which are disappearing throughout the world. The problem with that analogy is that, unlike hunters, natural predators target the small, the weak, and the sick. Hunters, on the other hand, tend to target the largest, strongest individuals with the largest hides, horns, tusks or antlers.”

It’s not just Big Horned sheep, elephants are also changing.

“Tusks used to make elephants fitter, as a weapon or a tool in foraging—until ivory became a precious commodity and having tusks got you killed. Then tuskless elephants, products of a genetic fluke, became the more consistent breeders and grew from around 2 percent among African elephants to more than 38 percent in one Zambian population, and 98 percent in a South African one. In Asia, where female elephants don’t have tusks to begin with, the proportion of tuskless elephants has more than doubled, to more than 90 percent in Sri Lanka. But there’s a cost to not having tusks. Tusked elephants, like the old dominant males on Ram Mountain, were “genetically ‘better’ individuals,” says Festa-Bianchet. “When you take them systematically out of the population for several years, you end up leaving essentially a bunch of losers doing the breeding.”

The effects that are taking place are difficult to link solely to hunting pressure @ this early stage because evolutionary changes happen so slowly but it doesn’t take a rocket scientist or hundreds of years of evolution to observe what’s happening.  Trophy hunters target the “biggest and the best”, therefore there are fewer of these alpha animals to pass on their genetics.

 The solution is to err on the side of caution and ban trophy hunting entirely. It’s a cruel and heartless enterprise, there would be no down side to freeing animals from this torture.  It doesn’t belong in a civilized society and should  be eliminated for purely ethical reasons BUT if it’s actually upsetting the natural process and weakening animal species, then all the more reason to rid the world of it.

A 2009 Newsweek article explains it all. Hunters not only don’t play the same positive  role as apex predators, like the wolf and grizzly bear but may be the cause of a deadly reverse evolution.

How Hunting is Driving “Evolution in Reverse.”

It’s Survival of the Weak and Scrawny

Jan 2, 2009 7:00 PM EST

Researchers see ‘evolution in reverse’ as hunters kill off prized animals with the biggest antlers and pelts.

Some of the most iconic photographs of Teddy Roosevelt, one of the first conservationists in American politics, show the president posing companionably with the prizes of his trophy hunts. An elephant felled in Africa in 1909 points its tusks skyward; a Cape buffalo, crowned with horns in the shape of a handlebar mustache, slumps in a Kenyan swamp. In North America, he stalked deer, pronghorn antelope, bighorn sheep and elk, which he called “lordly game” for their majestic antlers. What’s remarkable about these photographs is not that they depict a hunter who was also naturalist John Muir’s staunchest political ally. It’s that just 100 years after his expeditions, many of the kind of magnificent trophies he routinely captured are becoming rare.

Elk still range across parts of North America, but every hunting season brings a greater challenge to find the sought-after bull with a towering spread of antlers. Africa and Asia still have elephants, but Roosevelt would have regarded most of them as freaks, because they don’t have tusks. Researchers describe what’s happening as none other than the selection process that Darwin made famous: the fittest of a species survive to reproduce and pass along their traits to succeeding generations, while the traits of the unfit gradually disappear. Selective hunting—picking out individuals with the best horns or antlers, or the largest piece of hide—works in reverse: the evolutionary loser is not the small and defenseless, but the biggest and best-equipped to win mates or fend off attackers.

When hunting is severe enough to outstrip other threats to survival, the unsought, middling individuals make out better than the alpha animals, and the species changes. “Survival of the fittest” is still the rule, but the “fit” begin to look unlike what you might expect. And looks aren’t the only things changing: behavior adapts too, from how hunted animals act to how they reproduce. There’s nothing wrong with a species getting molded over time by new kinds of risk. But some experts believe problems arise when these changes make no evolutionary sense.

Ram Mountain in Alberta, Canada, is home to a population of bighorn sheep, whose most vulnerable individuals are males with thick, curving horns that give them a regal, Princess Leia look. In the course of 30 years of study, biologist Marco Festa-Bianchet of the University of Sherbrooke in Quebec found a roughly 25 percent decline in the size of these horns, and both male and female sheep getting smaller. There’s no mystery on Ram Mountain: male sheep with big horns tend to be larger and produce larger offspring. During the fall rut, or breeding season, these alpha rams mate more than any other males, by winning fights or thwarting other males’ access to their ewes. Their success, however, is contingent upon their surviving the two-month hunting season just before the rut, and in a strange way, they’re competing against their horns. Around the age of 4, their horn size makes them legal game—several years before their reproductive peak. That means smaller-horned males get far more opportunity to mate.

Other species are shrinking, too. Australia’s red kangaroo has become noticeably smaller as poachers target the largest animals for leather. The phenomenon has been most apparent in harvested fish: since fishing nets began capturing only fish of sufficient size in the 1980s, the Atlantic cod and salmon, several flounders and the northern pike have all propagated in miniature.

So what if fish or kangaroos are smaller? If being smaller is safer, this might be a successful adaptation for a hunted species. After all, ” ‘fitness’ is relative and transitory,” says Columbia University biologist Don Melnick, meaning that Darwinian natural selection has nothing to do with what’s good or bad, or the way things should be.
