Boar: a tusked Eurasian wild pig from which domestic pigs are descended.

HAIFA DISPATCH

Where Boars Hog the Streets

Groups of boars have become an unavoidable presence in Haifa. Some human residents are charmed, but others are annoyed or frightened and now carry sticks on walks.

HAIFA, Israel — The wild pigs of Haifa might not fly, but they seem to do almost everything else.

The boars snooze in people’s paddling pools. They snuffle across the lawns. They kick residents’ soccer balls and play with their dogs. They saunter down the sidewalks and sleep in the streets. Some eat from the hands of humans, and they all eat from the trash.

The wild boars of Haifa, in short, are no longer particularly wild.

Once largely confined to the many ravines that slice through this hilly port city on the Mediterranean, the boars have become increasingly carefree in recent years and now regularly venture into built-up areas, undeterred by their human neighbors.

“It became like an everyday thing,” said Eugene Notkov, 35, a chef who lets his dog play with the boars that putter around the local parks. “They’re a part of our city,” he added. Bumping into one is “like seeing a squirrel.”

In many countries, animal sightings increased after the pandemic began and people deserted public spaces. But Haifa’s boars started their conquest well before the coronavirus wrought its havoc. In 2019, residents reported 1,328 boar sightings to the city authorities — almost 40 percent more than the 2015 total. The Haifa City Council declined to release data for 2020.

The growing presence of the boars has sparked a rumpus in local discourse. For some, the boars are a menace, and the Council is to blame for their continued presence. For others, they are a charming addition to an already unusual place.

Israel’s third-largest city, with a population of nearly 300,000, Haifa has an eccentric topography. Built on the side of Mount Carmel, the city in Israel’s north is divided between districts that line a flat waterfront and neighborhoods that straddle a rugged mountaintop. Ravines, or “wadis,” run through the city, creating a rare blend of urban and natural (albeit one often pockmarked by industrial waste).

“It’s a secret garden,” said Rona Shahar, a painter and Haifa resident. “And there is a magical side to it.”

In their quest for food, boars regularly gobble the grass on people’s lawns, or rifle chaotically through trash cans.

In their quest for food, boars regularly gobble the grass on people’s lawns, or rifle chaotically through trash cans.

Haifa’s ethnic makeup is also atypical: It is one of the few Israeli cities where Jews live alongside significant numbers of Palestinian citizens of Israel, who form about 10 percent of the city’s population. It is the home of the leader of the country’s largest Arab political party, and its residents elected a female mayor before Jerusalem or Tel Aviv.

“I wish we could all in Israel learn to live like they live in Haifa,” said Edna Gorney, a poet, ecologist and lecturer at the University of Haifa. “It’s an example of coexistence — not only between Arabs and Jews, but also between humans and wildlife.”

For dreamers like Ms. Shahar, the painter, it feels almost unsurprising that boars should live cheek by jowl with Haifa’s humans. After moving to Haifa in 2008, she found a city that lends itself to the surreal, and began a series of paintings and drawings that explored what it would look like if the city were overrun with friendly tigers.

“I just had no idea there would actually be wild animals roaming the streets,” said Ms. Shahar. “It seems appropriate in some way.”

No one quite agrees why the boars entered Haifa in such high numbers. Some wonder if a huge fire in and around Haifa in 2016 destroyed the boars’ natural habitat, forcing them into the city. Others claim it was the mayor’s decision in 2019 to stop shooting the boars.

But the statistics show that the boars’ forays were already rising by the time the shooting stopped. And ecologists say the boars still have plenty of food in the nearby ravines outside Haifa. The real reason for their presence in the city, said the Haifa Council’s in-house ecologist, is that humans are leaving too much food waste in places that are even more accessible than the ravines.

“It’s easy to find food in the city,” said Yael Olek, the municipal ecologist. “And they don’t have to forage for it for a long time.”

Whatever the cause of their presence, the boars have sparked real fury among some parts of the population. For every Rona Shahar, there is someone who sees the boars as a danger and a pest.

In their quest for food, boars regularly gobble the grass on people’s lawns, or rifle chaotically through their trash cans. And while many boars have become almost tame in their behavior around humans, eating food from residents’ hands, some are still highly aggressive, particularly when with their young. In January, a boar bit a pensioner in the leg — the day after another boar made off with a schoolgirl’s pink school bag.

“They are controlling the streets now,” said Assaf Schechter, 43, a port worker confronted recently by a boar on his porch. “It’s a very crazy situation.”

Mr. Schechter’s teenage daughter sometimes calls him for moral support after late-night boar encounters, he said. His mother-in-law, Esti Shulman, has taken to carrying a stick in the street, after being run off the sidewalk recently by a pack of boars.

“They should collect the little ones and put them in a park,” said Ms. Shulman, 75, a retired bookkeeper. “Or take them to the Golan Heights! Or shoot them!”

This ire has been increasingly aimed at the mayor, Einat Kalisch-Rotem. At a recent public meeting convened by the Council to discuss the boar issue, hundreds of residents showed up to harangue her for three hours.

“This past Saturday,” said an Sarit Golan-Steinberg, a lawyer and Council member, “my husband came running back home because he ran into a 150-kilogram female boar!”

“Tell me,” Ms. Golan-Steinberg demanded, “do you think this is funny?”

Ms. Kalisch-Rotem has hardly been idle in the face of these powerfully built animals, which can top 300 pounds. Under her watch, the Council has fenced off parks and ravines, to choke the access points to the city — and fixed chains to trash cans, to limit access to food waste. But since the municipality has declined to release more recent data about the presence of boars, it is unclear whether these strategies have had an effect.

In the meantime, amateurs have attempted their own solutions. One group tried to build an app that could deter boars with subsonic sound waves. Others discussed leaving lion dung near boar hot spots, in the hope that the smell would deter the pigs.

Prof. Dan Malkinson, a wildlife expert at the University of Haifa, investigated whether boars could be repelled with urine, conducting his own informal experiment beside the lemon and loquat trees at the bottom of a friend’s garden.

“At night, I would go out, after a drink, and recycle the beer,” Professor Malkinson said. “It’s two for the price of one — you fertilize the trees and you try to deter the wild boars.”

Sadly, however, the boars kept coming.

But Professor Malkinson, who has researched the boars for years, and even tracked them with collars fitted with GPS devices, wonders if the boars are really Haifa’s biggest problem.

The tension that most needs a solution, he said, is not between boars and humans — but among the humans themselves.

“Essentially the conflict is between those who oppose having wild boars in the city and those who don’t,” Professor Malkinson said.

“It’s not an ecological problem,” he added. “It’s a social problem.”

I used to eat pork steaks but these days I prefer chicken thighs. I never met a chicken thigh I didn't like.

Texas Pork Producers Association

History of Pork


The pig dates back 40 million years to fossils, which indicates that wild pig-like animals roamed forests and swamps in Europe and Asia. By 4900 B.C., pigs were domesticated in China, and by 1500 B.C., they were being raised in Europe.

On the insistence of Queen Isabella, Christopher Columbus took eight pigs on his voyage to Cuba in 1493. However, it is Hernando de Soto who could be dubbed “the father of the American pork industry.” The explorer landed with America’s first 13 pigs at Tampa Bay, Fla., in 1539.

Native Americans reportedly became very fond of the taste of pork, resulting in some of the worst attacks on the de Soto expedition. By the time of de Soto’s death three years later, his pig herd had grown to 700 head, not including the ones his troops had consumed, those that ran away and became wild pigs (the ancestors of today’s feral pigs or razorbacks) and those given to the Native Americans to help keep peace.

America’s Pork Industry Had Begun

Pig production spread throughout the new colonies. Hernando Cortez introduced hogs to New Mexico in 1600, and Sir Walter Raleigh brought sows to Jamestown Colony, now in Virginia, in 1607.

Semi-wild pigs conducted such rampages in the grain fields of New York that colonists who owned a pig 14 or more inches high had to put a ring in the pig’s nose. On Manhattan Island, a long solid wall was constructed on the northern edge of the colony to control roaming herds of pigs, as well as to protect the colonists from native Americans. This area is now known as Wall Street.

The pig population in the Pennsylvania colony num­bered in the thousands by 1660. As the 17th century closed, the typical farmer owned four or five pigs, supply­ing salt pork and bacon for his table, with surpluses sold as barreled pork. Following a practice that had become common in Pennsylvania, pigs were fed a diet of native American corn.

After the Revolutionary War, pioneers began head­ing west, taking their indispensable pigs with them. A wooden crate filled with young pigs often was hung from the axles of prairie schooners.

As western herds grew, so did the need for pork pro­cessing facilities. Packing plants began to spring up in major cities. Pigs were first commercially harvested in Cincinnati, which became known as Porkopolis. More pork was packed there than any other place in the mid- 1800s.

“Drovers” Herd Pigs to Market

Moving pigs to market in the 1850s was no small undertaking. “Drovers” herded their pigs along trails, which later developed into railroad routes. Between 40,000 and 70,000 pigs were driven from Ohio to eastern markets in any one year. Drivers, the drovers’ hired hands, each managed up to 100 hogs, and the herds moved five to eight miles a day, covering distances up to 700 miles.

The refrigerated railroad car transformed the meat industry when it was introduced shortly after the Civil War. It enabled packing plants to be centralized near points of production instead of near points of con­sumption. Large “terminal markets” with railroad access developed in major cities, such as Chicago, Kansas City, St. Joseph, Mo.; and Sioux City, Iowa. Large packing plants were located adjacent to these stockyards. Live pigs were shipped via railroad to the markets, and pork was shipped, again mainly by rail, to consumers nationwide.

As a result of these transportation developments, the pork industry relocated to the upper Midwest, where ample amounts of feedgrains were produced, and the “Corn Belt” also became known as the “Hog Belt.” In fact, Iowa, Illinois, Minnesota, Nebraska, Indiana and Missouri held the top six spots in state rankings for pork production for many years. Iowa is still No. 1.

The 1980s and 1990s brought major technological developments in the pork industry, some of which allowed production to grow dramatically in states not known for pig production. The most notable growth occurred in North Carolina, which is now the second largest pork- producing state.

Despite inherently more expensive feed, North Carolina producers became cost competitive by using pigs with the genetic capability for higher reproductive efficiency and enhanced lean muscle growth, resulting in better feed efficiency. They also captured economies of size and developed pig-raising methods that controlled disease, and improved productive efficiency. Many producers in other areas have now adopted these same methods.

Today the United States is one of the world’s lead­ing pork-producing countries. Also, the U.S. became the largest pork exporter in 2005 and remains so today. U.S. production accounted for 10 percent of total world supply in 2012.

Where are the chickens?

Map showing domestication of animals in years before present:

Attachment image

UPDATE: Chickens are very important to me because I eat chicken thighs every day. So I looked it up and I found this stuff:

"Chickens initially became domesticated between 8,000 and 10,000 years ago. There's also genetic evidence to suggest that there were simultaneous but independent domestication events in different parts of Asia and India."

A Brief History of Chickens

Posted by TF Oren


Chickens
Once relegated mostly to farms and breeding facilities, chickens are now commonplace as pets.
Sure, they're not the most glamorous birds, but they have quite an interesting story, and that story begins in the dinosaur age. Curious? Here's a primer on chicken evolution and domestication.

The chicken's origins lie in a group of dinosaurs called the theropods, which evolved into two categories some 230 million years ago: the Ceratosauria and the Tetanurae. The Ceratosauria then split again into the ceratosaurids and the coelophysoids. The latter eventually resulted in the genetic line that produced the Tyrannosaurus rex.

In 2003, paleontologist Jack Horner discovered a 68-million-year-old T. rex fossil in Montana. Inside its thigh bone, scientists found a blood vessel they were able to analyze. Their phylogenetic analysis revealed that genetically speaking, the domestic chicken is the closest living relative of T. rex.


Chickens

Now, let's fast-forward a bit to examine the chicken's more recent evolutionary history.

The modern chicken, as we know it, is descended from several of four known species of wild jungle fowl (Gallus) that inhabited parts of Southeast Asia about 50 million years ago.

Scientists believe the red jungle fowl, Gallus gallus, is the most likely progenitor of the modern chicken, although research suggests that the domestic chicken's yellow skin is a trait inherited from the gray jungle fowl, Gallus sonneratii.

So, it's more than likely that today's chicken has multiple ancestors.


Chickens

Chickens initially became domesticated between 8,000 and 10,000 years ago. There's also genetic evidence to suggest that there were simultaneous but independent domestication events in different parts of Asia and India.

According to computational biologist Michael Zody, it's difficult to pinpoint the domestic chicken's origins and domestication history because the long history of interbreeding between wild and domesticated birds has resulted in inconclusive DNA evidence.

Once chickens were domesticated, they were used for food, fighting, and religious purposes. Various cultures spread them around the world over the course of thousands of years via migration, trade, and territorial conquests.


Chickens

The Polynesians brought chickens to the Pacific coast of South America around 1200 A.D. Over a period of several hundred years, and mostly due to the popularity of cockfighting, inhabitants of the New World became well versed in chicken care and breeding. Spanish explorers brought chickens to North America, and chickens soon became widely dispersed across the continent.

The chicken reached Europe (Romania, Turkey, Greece, Ukraine) about 3000 BC. Introduction into Western Europe came far later, about the 1st millennium BC. Phoenicians spread chickens along the Mediterranean coasts as far as Iberia.

From dinosaurs to backyard pets, chickens have been around, in some form or another, for millions of years.

Can you believe domesticated chickens are the ancestor of the T. rex? No wonder when my broody hen starts to growl at me, I immediately think of a dinosaur! You don't need a DNA analysis over here to know these are little dinosaurs running around our yard.

The history behind one of the most popular backyard livestock animals is fascinating! The importance of egg-laying hens and chicken eggs (generally speaking) to society has been in existence since the beginning...of everything!

My chickens enjoy a free-range lifestyle and I cannot imagine keeping them in their secure coop area all day. If they were once wild species then it makes sense they that would enjoy room to scratch and peck above and beyond even eating! Egg production in our flock actually increased after we start letting them free-range all day.

So enjoy those hens that lay eggs for you each day! Their ancestors had to travel far and wide to get here and look at how many 'American' heritage breeds there are today in the United States!

The chicken is one of the most dominant symbols in our history dominating aspects of our culture and culinary habits. For goodness sake, chickens joined the Romans in battle to help predict the outcomes of war!

Pigs, rats, and Christians are unable to understand natural selection.


"I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection"
-- Charles Darwin

"In the struggle for survival, the fittest win out at the expense of their rivals because they succeed in adapting themselves best to their environment."
-- Charles Darwin

"To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree. Yet reason tells me, that if numerous gradations from a perfect and complex eye to one very imperfect and simple, each grade being useful to its possessor, can be shown to exist; if further, the eye does vary ever so slightly, and the variations be inherited, which is certainly the case; and if variation or modification in the organ be ever useful to an animal under changing conditions of life, then the difficulty of believing that a perfect and complex eye could be formed by natural selection, though insuperable by our imagination, can hardly be considered real."
-- Charles Darwin

But Natural Selection, as we shall hereafter see, is a power incessantly ready for action, and is immeasurably superior to man's feeble efforts, as the works of Nature are to those of Art.
-- Charles Darwin

When we no longer look at an organic being as a savage looks at a ship, as something wholly beyond his comprehension; when we regard every production of nature as one which has had a long history; when we contemplate every complex structure and instinct as the summing up of many contrivances, each useful to the possessor, in the same way as any great mechanical invention is the summing up of the labour, the experience, the reason, and even the blunders of numerous workmen; when we thus view each organic being, how far more interesting - I speak from experience - does the study of natural history become!
— Charles Darwin

Multiply, vary, let the strongest live and the weakest die.
— Charles Darwin

Nothing is easier than to admit in words the truth of the universal struggle for life, or more difficult--at least I have found it so--than constantly to bear this conclusion in mind.
— Charles Darwin

natural selection: The nonrandom, differential reproduction of alleles from one generation to the next. This usually results from the carriers of some alleles being better able to survive or reproduce in their environments than the carriers of alternative alleles.
-- Jerry Coyne

allele: A particular form of a given gene produced by mutation. For example, there are three alleles at the protein-coding gene that produces our blood type: the A, B, and O alleles. All are mutant forms of a single gene that differ only slightly in their DNA sequence.
-- Jerry Coyne

Chance alone cannot explain the marvelous fit between individuals and their environment. And it doesn't. True, the raw materials for evolution--the variations between individuals--are indeed produced by chance mutations. These mutations occur willy-nilly, regardless of whether they are good or bad for the individual. But it is the filtering of that variation by natural selection that produces adaptations, and natural selection is manifestly not random. It is a powerful molding force, accumulating genes that have a greater chance of being passed on to others, and in so doing making individuals even better able to cope with their environment. It is, then, the unique combination of mutation and selection--chance and lawfulness--that tells us how organisms become adapted.
-- Jerry Coyne

National Geographic Magazine defined natural selection at http://ngm.nationalgeographic.com/ngm/0411/feature1/fulltext.html:

The gist of the concept is that small, random, heritable differences among individuals result in different chances of survival and reproduction—success for some, death without offspring for others—and that this natural culling leads to significant changes in shape, size, strength, armament, color, biochemistry, and behavior among the descendants. Excess population growth drives the competitive struggle. Because less successful competitors produce fewer surviving offspring, the useless or negative variations tend to disappear, whereas the useful variations tend to be perpetuated and gradually magnified throughout a population.

National Geographic also defined speciation:

Genetic changes sometimes accumulate within an isolated segment of a species, but not throughout the whole, as that isolated population adapts to its local conditions. Gradually it goes its own way, seizing a new ecological niche. At a certain point it becomes irreversibly distinct—that is, so different that its members can't interbreed with the rest. Two species now exist where formerly there was one. Darwin called that splitting-and-specializing phenomenon the "principle of divergence." It was an important part of his theory, explaining the overall diversity of life as well as the adaptation of individual species.

http://en.wikipedia.org/wiki/Natural_selection

Natural selection is the gradual, non-random, process by which biological traits become either more or less common in a population as a function of differential reproduction of their bearers. It is a key mechanism of evolution.

Variation exists within all populations of organisms. This occurs partly because random mutations cause changes in the genome of an individual organism, and these mutations can be passed to offspring. Throughout the individuals’ lives, their genomes interact with their environments to cause variations in traits. (The environment of a genome includes the molecular biology in the cell, other cells, other individuals, populations, species, as well as the abiotic environment.) Individuals with certain variants of the trait may survive and reproduce more than individuals with other variants. Therefore the population evolves. Factors that affect reproductive success are also important, an issue that Charles Darwin developed in his ideas on sexual selection, for example.

Natural selection acts on the phenotype, or the observable characteristics of an organism, but the genetic (heritable) basis of any phenotype that gives a reproductive advantage will become more common in a population (see allele frequency). Over time, this process can result in populations that specialize for particular ecological niches and may eventually result in the emergence of new species. In other words, natural selection is an important process (though not the only process) by which evolution takes place within a population of organisms. As opposed to artificial selection, in which humans favour specific traits, in natural selection the environment acts as a sieve through which only certain variations can pass.

Natural selection is one of the cornerstones of modern biology. The term was introduced by Darwin in his influential 1859 book On the Origin of Species,[1] in which natural selection was described as analogous to artificial selection, a process by which animals and plants with traits considered desirable by human breeders are systematically favored for reproduction. The concept of natural selection was originally developed in the absence of a valid theory of heredity; at the time of Darwin's writing, nothing was known of modern genetics. The union of traditional Darwinian evolution with subsequent discoveries in classical and molecular genetics is termed the modern evolutionary synthesis. Natural selection remains the primary explanation for adaptive evolution.
