Fossils from one of the oldest weeds, the age of more than one billion years Source:

The Days when scientists used weak by today's standards the computers are long gone. Today at the disposal of researchers there are powerful computers, microscopes and other modern equipment, so there is nothing surprising in the fact that scientific discoveries are becoming more awesome. A few years ago, scientists studying the fossils of ancient animals and plants, managed to unearth the fossilized remains of algae, whose age was estimated at 800 million years. But now, thanks to new technologies, they managed to find tiny samples of green algae called Proterocladus antiquus older than one billion years. But why this discovery is considered very important and what scientists have learned about the ancient world, examining fossils?

According to the scientific publication , fossils of algae with the length of a few millimeters were found in Liaoning province, located in Northern China. Though the age of water plants and is estimated at a billion years, they are not the oldest in history. And the thing that earlier scientists were able to find algae species Bangiomorpha pubescens, whose age was estimated at 1,047 billion years. Only here new find interested scientists more because they found not red algae, and green. They got the opportunity once again to prove that plants originally appeared in the water and then walked on land.

How did plants?

It is believed that green plants appeared on the planet between 2.5 billion and 635 million years ago. Until now, scientists were pretty hard to name a more precise date for the appearance of green plants on Earth, but due to the discovery of a larger number of fossilized algae, to make it becomes easier. For example, we now know that a billion years ago in the waters of our planet exactly grow green algae Proterocladus antiquus. Most likely, over time, they evolved and, like animals, came out of the water onto dry land. According to paleontologist Shuhai Xiao, development of land plants began around 450 million years ago.

There is a small probability that were studied under microscope algae are the progenitors of all existing plants, ranging from huge trees growing on and finishing them with moss. Most likely found algae grew in the oceans, because they are in form and dimensions similar to the plants that grow in the oceans today.

It is Worth noting that the assumption that green plants originated in the ocean and gradually moved onto land, may not like some scientists. The fact that some of them believe that plants originally appeared in fresh water, and then appeared in the ocean and on land. They would love to prove his theory, except that at the moment scientists have not found so ancient algae that grow in fresh water.

Generally, as everything that exists in this world, algae are of interest to scientists. Over billions of years these plants have evolved to such an extent that today can be a danger to people and animals. Just last year, we told you about how the so-called blue-green algae can cause poisoning and cause of death. Read more about these plants and their victims can be found in our .
