The size of the animals changes over time. This is not new in nature. It is a part of the process of fully growth. Along with changes in the environment, animals also try to mold themselves. Sometimes their size is small, sometimes big. This change has been happening for thousands of years. But there was a time when humans started joining this process. As humans started cultivating, animals started raising and village and city started to settle, so there were very big changes in the shape of animals.
Recently, scientists of Montpelie University in France have done a big research. He examined the bones of animals which had met 311 places in southern France. In total, 2,25,780 bones were studied, which were in the last 8,000 years. This research was previously focused on pets only, but later when scientists found a lot of evidence of wild animals, they increased the scope of research. In such a situation, let us know whether animals became small and big because of humans really.
Did animals become small and big because of humans
According to research, between 1000 to 2000 AD, from medieval to modern era, there were different changes in the pet and wild animals. The researcher said that wild animals became smaller in this period, while pets grew up. As humans started settling houses in the forests, started making roads and started farming, the size of the forests started decreasing. This causes wild animals such as foxes, weeds, rabbits, deer. The area of their stay became small. Due to low space, both food and security became difficult, due to which the growth of their body stopped and the size became smaller. Apart from this, the increase in hunting has also become a major reason.
Which animals grew up?
On the other hand, humans started making some animals domesticated. Human beings now started raising animals for their benefits like milk, meat, wool, eggs. So they they, sheep, goat, cow, boar, chicken. Like began breeding animals. That means the animals that were bigger and powerful, the ahead of them were prepared from them. This process is called selective breeding. The effect of this was that over time the size of pets increased. Due to this, the influence of human has increased a lot in the last few thousand years. Now not only the weather, food or forest is affected, but human activity such as hunting, farming, settlements, raising animals, controlling their breeds. All these affect the growth of animals very deeply.
