Interesting Facts on Biology

There are many interesting facts in the world that surrounds us. At the same time, most of them are non-trivial, often cause confusion, and with the help of others it is very easy to win the argument from opponents.

Therefore, we will acquaint you with the most interesting facts from biology.

In 2014, Japanese scientists from the Osaka Institute of Biological Sciences discovered a protein that plays an important role in signaling between ribbon synapses of the human eye’s photoreceptors and dendrites. They called this protein “pikachurin” – in honor of the movements with the speed of lightning and electrical abilities of Pikachu Pokemon.

Life on Earth already existed 3.4 billion years ago, when carbon dioxide and methane dominated the atmosphere, and there was practically no oxygen. This conclusion scientists made, analyzing the fossils found in Australia. They turned out to be microorganisms that exist due to oxygen, but due to sulfur compounds. Sulfur bacteria are similar to them and today they live in geysers, volcanoes and hot springs.
