Ancient moss species has been prepared for humanity to appear

Ancient terrestrial plants, first of all mosses have played a key role in the emergence of life on earth. Because it is because of their activity that in the atmosphere of our planet we have had enough oxygen to see its existence today.

As the British experts at Exeter claim, many complex organisms, including humans, must be grateful for the moss. To this day it is thought that the first terrestrial plants on our planet are most similar to mosses, partly because they do not have the same blood circulation system, allowing water and water transport Mineral.

But the rough structure does not prevent ancient moss from proliferation, spreading a large area for living activities to affect the atmospheric composition of the planet.

Without the evolution of the rudimentary moss, perhaps there is no human right now.

Scientists have modeled on computers and discovered that it takes nearly 50 million years for moss to produce atmospheric oxygen equivalent to current indicators.

But nearly 420-400 million years ago, as scientists claim, the ratio of oxygen in the air has reached 21% and remains the same until now. This is a key condition for developing the most complex life forms among the present patterns, including human evolution.

Currently, oxygen concentrations in the planetary atmosphere are generally stable because the living activities of different organisms and natural processes are generally a stable, balanced system between oxygen production and consumption.

Accordingly, oxygen not only allows humans and animals to breathe, but also transforms into ozone and thus protects the earth from excessive electromagnetic radiation that is dangerous.

Commenting on the results of the study published in the scientific journal PNAS, lead author Tim Lenton said: "I always think without the evolution of the primitive moss, perhaps there is no human being at the moment ".
