Amazing mysteries of nature

Despite the level of development of modern science and technology, there is still a large number of unsolved mysteries in the world. This suggests that life, in all its diversity, is much more complex than we could imagine. I represent a selection of 10 unexplained mysteries of nature.
The closer to the equator - the larger quantity of species
It was found that the equatorial climate prevails the greatest diversity of species, not only of plants and animals, but even of the simplest viruses. Any type of virus like Ebola emerges and spreads from Africa or South America. There are many theories about why the greatest species
diversity is concentrated near the equator, but they all contradict each other.

Too much phytoplankton
Phytoplankton are tiny organisms that live in the oceans. Their main secret lies in the fact that
they are too much of them in the world. The basic theory of evolution makes impossible to survive such a large number of different organisms.

Cambrian explosion
For the first time this oddity was discovered by Roderick Murchison. By studying fossils of ancient times, found in the relevant deposits, he saw that layers of these deposits are separated by a sharp boundary. Below this limit they were extremely poor of biological remains and demonstrated the ubiquity of only the simplest single-celled organisms - bacteria and algae,
and then, since the Cambrian period, about 550 million years ago, they have suddenly acquired an unprecedented wealth of new biological forms. Modern science has solved part of the mystery. But the mystery of the Cambrian explosion still remains and now the conversation is not about how complex life forms emerged out of nowhere, but why so many of them suddenly
acquired a mineral skeleton.

Oxygen Dependence
Until recently scientists have argued that all multicellular organisms on Earth anyway depend on the content of oxygen in the atmosphere. However, a few years ago animals were found in the
Mediterranean Sea (important clarification: not unicellular, namely animals), which can live without oxygen. And this wasn't one case, which can be attributed to a spontaneous mutation, but three different species of invertebrates lucifers. Scientists are still trying to unravel the mystery of their evolution.

Magnetic compass in cows
Google Earth service made possible to study thousands of images of grazing cows and see a very strange pattern. These animals are always turning heads to the north or south at the time
when they eat or drink. This occur on all continents, regardless of weather conditions, terrain and other factors.

The alkaloids in plants
Scientists have found that modern plants contain about 7,000 different types of alkaloids. And
the most common of these is morphine. Scientists can't yet explain why the plants need alkaloid.

Why mammoths became extinct?
To this day, in the north of Siberia and Alaska, scientists sometimes find whole, perfectly
preserved mammoth carcasses. It could be adults and small mamonts. But most interesting is that in the stomachs of these mammoths, and not only in the stomach, even just in the mouth of some specimens was found green grass. This indicates that these animals died unexpectedly, all at once. Why this happened is still unknown to scientists.

Argentine ants
These ants are the only living organisms on earth except man, who could settle their own three continents. Scientists still can't explain how they managed to do this. Appearing in South
America, they were able come to Europe and Asia. However, their genetic code all the time remained unchanged.

The emergence of species out of nowhere
This mystery has been alive for many years. The fact is that many species of plants and animals
on our planet appeared from nowhere. They did not have ancestors from which they have evolved, they have just appeared. This was the case with the amphibians: no one knows the stage when fish gave life to amphibians. The earliest land animals had already well-developed
limbs, shoulder and pelvic girdle, ribs and clearly expressed head.

Amazing balance of the universe
This mystery is common not just for the Earth, where we can observe the incredible consistency
of the various parameters and factors that made possible the intelligent life. It is about the entire universe, which is perfectly balanced. Take for example the sun. If nuclear power of atoms was less only a few percentage points, there would be no fuel for solar energy, and thus life on Earth. And if nuclear power was a little more, the sun would have exploded. Changing of the
distance from the Sun to the Earth by only 2% would make life on Earth impossible. Why does everything in the universe so perfectly balanced - it is a mystery.
