What the animals we eat looked like before humans began breeding them for food _ daily mail online

Records suggest that early humans went from gathering their food to hunting it about 2 million years ago and began raising animals about 10,000 years ago.

In the 19th century, evolutionary biologist Charles Darwin noted that breeding led to ‘striking differences between farm animals and plants and their wild counterparts’.

Although this observation helped layout the foundation for Darwin’s theory of evolution, it was also theorized about the future of the meat we would put on our plates.

It was sheep, goats, cattle, pigs and geese that were among the first animals to be specifically raised for human consumption, which didn’t occur until around 10,000 years ago, according to Ancient History Encyclopedia.

Goats and sheep were the earliest to be bred for food around 7000 BC, pigs 6500 BC and horses were tamed by 4000 BC, a majority of them were used for work and warfare, but some cultures raised them as a food source.


This site suggested that the killing of animals for food started at least 2 million years ago, which also indicates that meat eating could have triggered even bigger changes in the Homo species.

‘Just about that time — 2 million years ago — we see big shifts in the human fossil record of increase in brain size, increase in body size and hominins leaving Africa for Eurasia,’ Joseph Ferraro, an archaeologist at Baylor University in Waco, Texas, told LiveScience.

Prior to this discovery, researchers believed this shift in diet occurred 1.8 million years ago – which coincided with evidence found in Tanzania.

Eventually these bireds would become bowlegged, because their frames couldn’t support the intense growth and they could not long stand up straight.

The National Turkey Federation reports that turkey consumption has doubled over the last 30 years—today, the average American eats 16 pounds of turkey per year.

The most extreme example of breeding in cows is seen in the Belgian Blue (pictured), which has twice the amount of muscle than its earlier wild relatives

The breeding of cattle is traced back to the 18th century and credited to Robert Bakewell, who is said to have raised Wild Cattle of Chillingham into larger and meatier animals than their ancestors.

The most extreme example of breeding in cows is seen in the Belgian Blue, which has twice the amount of muscle than its earlier wild relatives.

Breeding was also used to reduce infection among cows, by selective breeding humans are able to maintain the animal’s health and avoid certain diseases.

Goats and sheep were the earliest to be bred for food (7000 BC), pigs in 6500 BC and horses were tamed by 4000 BC, a majority of them were used for work and warfare, but some cultures raised them as a food source.

Chickens were also domesticated around 10,000 years ago, but were first bred for cock fighting in Southeast Asia, reports National Geographic.

Some of the genes used during the process may have been taken from other foods that people are allergic to and they have no way of knowing about it.

These modern-day animals look very different from their wild ancestors such as the chicken that once weight just two pounds and now some hit 17 pounds.

Robert Bakewell also worked with breeding these animals and would raise them to be big, delicate boned sheep, with high-quality fleece and large foreheads.

Their ears became more of a lop ear than an erect ears and their horns that the wild sheep possessed were weakened and disappeared from many breeds.

Researchers suggest that the switch from gatherers to hunters, triggered a genetic change that enhanced the process of eating fats, reports National Geographic News.

In 2013, US authorities began discussion to grant approvals for the world’s first genetically modified fish, the Aquabounty salmon, which has had its genes altered so that it grows twice as fast as a normal fish.

Aquabounty salmon is produced through the insertion into the eggs of wild Atlantic salmon of a growth hormone gene from Chinook salmon, as well as a gene from a different type of fish called the ocean Eelpout.

Recently, a start-up announced it should have animal-free products on the market in three to four yeast and unveiled the first lab-grown meatball.

The firm says its cutting-edge technique produces 90 percent less greenhouse emissions, consumes less nutrients and doesn’t require antibiotics or other additives used in traditional meat production.

While generating one calorie from beef requires 23 calories in feed, Memphis Meats plans to produce a calorie of meat from just three calories in inputs.

In order to grow meat in a lab, Memphis Meats begins by isolating cow and pig cells that have the ability to regenerate, and ‘provides the cells with oxygen and nutrients such as sugars and minerals’.
