'Human' when was the beginning? New Discovery

Scientists have defined a new geological era, which began in 1610, according to a study. This era, the era is named or aynthrupusyn.
Scientists have shown that the arrival of Europeans in the Americas unprecedented impact on the planet, which has become a new geological era.
This study is published in the scientific journal Nature.
In fact, some experts believe that this time the Industrial Revolution in Europe in the 18th century began.
Geologists are divided into different periods of Earth history during which significant changes on the planet. These changes in the motion of continents, or a meteor hit the land of the big change in the weather are included.
We still formally 'hylusyn, who are living in the era after the collapse of the ice age 11,500 years ago had started.
But now scientists say that humans have changed dramatically to the ground. Effect of human beings on planet earth geologists identified the effects are seeking a clear sign, the 'golden index is called. The effects of rock, ice and silt, etc. are stored.
Study co-author and professor of University College London Mark mysln says: "We are finding that these indicators occur when you can tell that this time all the earth has changed.

With the arrival of Columbus to the Americas plants, animals and diseases intercontinental exchange began.
"If you look at all the geological periods away from the borders are also compiled on these principles."
This study shows that the era of the golden indicators such as occurred in 1610.
Scientists say that the arrival of Europeans in the Americas proved to be a harbinger of global change.
Another study author Dr Simon Lewis says, it was the international trade of animals and plants of the species around the world began to move from here to there.
'Wheat from Central America who come to Europe, Africa and China had grown into. South American potato UK, Europe and China began to grow in. On the other side were the commodity wheat in North America and South America were counted. Become a mixture of species in the world.
"We saw that the animal species have begun to step over the continent, it had never happened before, it has begun the development of a new direction."
Silt found in the pollen record of this transformation is similar, but a team of scientists found and indexed, and he was the US from Europe in the form of these diseases.
Dr. Lewis told the BBC: "Five million people were killed in the continental United States, the majority of whom were farmers. (After his death) field again became forest, tropical forest, dry forest or grassland. Half the dry weight of a tree is carbon based, so all the trees of the atmospheric carbon removed so that the amount of global carbon dioxide was significantly decreased. And this can be seen in layers of ice. "
He said: "It gives us know the time is right to start, namely 1610. This icy layers of the lowest amounts of carbon dioxide. "
Commenting on the study, University of Leicester, said Dr. John zalasayyuc quite interesting ideas are presented in this study. He said: "It adds to the discussion on the human era. Historically proposed 1610 indicates a significant incident, but further evidence is needed. "
