Studies have shown that low oxygen levels have delayed the evolution of life on Earth by 2 billion years.

In earth to middle age, the evolution of organisms is delayed by 2 billion years due to the gradual decline in oxygen levels.
by the University of Exeter in The United States suggests that the bodies of early simple life may be associated with this.
, the cycle was finally broken with the rise of land plants.
-co-technology plants are growing rapidly around the world, greatly increasing the amount of oxygen in the atmosphere and leading the Earth out of the low-oxygen dead cycle.
, Feb. 20, Beijing time, according to foreign media reports, in the Earth to middle age, due to the gradual decline in oxygen content, biological evolution has been delayed by 2 billion years.
raises new questions about the origin of life on Earth.
do you keep oxygen at a low level for so long? A new study by the University of Exeter in the UK may provide an explanation for this.
study may explain why the "big oxidation event" that made a significant contribution to biological origin 2.4 billion years ago did not bring oxygen levels to today's levels.
to find out why oxygen levels remain low, the researchers created a computer model.
model shows that the bodies of early simple life may be related to it.
dead primitive creatures accumulate in sedimentary rocks beneath the surface.
as the earth's crust moves, the sediments are gradually brought to the surface to react with oxygen.
oxygen in the atmosphere, the faster it reacts with organic matter.
results, oxygen is consumed by sediments at almost the same rate as it is produced in the air.
this cycle has caused oxygen levels to remain low, delaying the evolution of complex life on Earth by 2 billion years.
, the cycle was finally broken with the rise of land plants.
-co-technology plants are growing rapidly around the world, greatly increasing the amount of oxygen in the atmosphere and leading the Earth out of the low-oxygen dead cycle.
, oxygen levels finally reached today's levels.
became land lords and evolved into humans.
"This is a period of dilemma in the history of the Earth.
," said Tim Lenton, co-author of the study and professor of geography at the University of Exeter.
complex forms of life could not have evolved on Earth at that time because there was not enough oxygen in the atmosphere, " he said.
And the lack of oxygen is because complex plants have not yet appeared, until the emergence of land-based plants, oxygen content only increased significantly, the evolution of life on Earth and the Earth's physical and chemical mechanisms are inextricably linked, living things to shape the earth into what we know, made a great contribution.
earth in turn affects the process of life, I think people must admit that their own come to this world is a miracle, but also to realize how amazing the earth is.
