Chickens have evolved millions of years in 60 years! What’s wrong with chickens?
In the 1950s, chickens were lighter than 1 kilo, and now weigh more than 4 kilos. 65 billion chickens are slaughtered every year in the world. So what’s wrong with the chickens?

In the 1950s, chickens were lighter than 1 kilo, and now weigh more than 4 kilo. If you think that 65 billion chickens have been slaughtered every year around the world, we can better understand how humanity shapes the planet and controls other living things.
Although the change and evolution of living things lasted millions of years, the change of chickens became very rapid thanks to humans. The rise in the type of chicken sold in the markets means the decline of wild chickens.
Finally, a study of chicken bones found in an archaeological site in London shows how different it is from the ancestors of today’s chickens. The results of the study conducted by a team from Leicester University were published in the Royal Society Open Science, England.
Dr. geologist at Leicester University. “The number of hens reaches is so high that the other bird species that live today are never able to reach it,” said Carys Bennett.

We live on the chicken planet!
When we look at the world-wide chicken figures, we see that we live on a chicken planet.
In 2014, 8 billion chickens were slaughtered and consumed. Other animals that are most slaughtered and consumed in the world are pigs (1.5 billion units in the same year) and cattle (0.3 billion units in the same year).
The number of restaurants owned by popular fried chicken brands around the world is 25,500.
70% of meat broth is grown in intensive production facilities.
The average life of meat broilers varies between 5 and 7 weeks.
There are around 23 billion chickens all over the world.)
In the 1800’s, the number of pigeons in the mailman ranged from 3 to 5 million. This species, almost completely extinct today, has been recorded as the highest number of wild birds in human history.

How did the chickens change from 1950s to today?
Researchers studying 2,000 years of archaeological records have obtained their data compared to wild hens and chickens produced in industrial plants. In this way, it is understood how the chickens have changed in the last 50 years and become the symbol of the period in which we live.
The results indicate that chickens, which were domesticated 8,000 years ago in South East Asia, have grown rapidly since 1950. As the chickens became heavier, the skeletal and muscular systems were adapted.
Dr. According to Bennett, the differences between the ancestors of the chickens produced in the plants were increasingly opened. Jan Zalasiewicz of the research team also underlined that a change in nature that would last millions of years would take place in a very short period of time, such as 60 years.
Here is the table showing the change of chick and chicken weights from 1950s to today.…

Human activity has changed from the beginning to the end of the world.
Researchers say we are entering an era called anthropocentric where human activity dominates climate and environment. Dr. “The activity of man has changed the landscape, the oceans, the atmosphere and the Earth. Modern chickens, which are vertebrate terrestrial creatures shaped by human beings, have become a symbol of our changing biosphere.”
Dr. When Bennet examined the rocks of the future generations from our era, he said that he would find cans, glass bottles, plastic and chicken bones and emphasized how much space the chickens occupy in human civilization in a humorous way.
Domesticated and raised animals are now the majority of animal species in the world, shaping the natural life.
