global warming,world's first animal

Some 520-540 million years ago, the life of animals evolved in the ocean and began to break organic matter at sea, thereby increasing carbon dioxide and low oxygen in the atmosphere.

Research published in Nature Communications, Exeter, Leeds and Antwerp Universities and the University of Vrije Brussel.

Exeter University professor Tim Lenton said, “Like insects in a garden, small creatures on the beach recycle together with brain materials-a process called bioturbation.”

“Because the impact of animals is so big, you will expect to see major changes in the environment when the entire sea level will change from an undisputed state into a biological situation.”

University of Antwerp Professor Filip Meysman said, “We actually saw a decrease in oxygen levels in the sea 520 million years ago.”

“But evidence from the rock record shows that the sediment was just a bit upset.”

Professor Simon Paulton of Leeds University said: “It meant that the animals living in the pirate were not very active at that time, and did not go very deep in the ocean.

“At first sight, it does not seem to add these two observations.”

Dr. Sebastian Van De Welde, lead author of Vrije Universiteit Brussel, explained: “The important factor was to realize that the biggest change in the lowest levels of animal activity is the change.

“It meant that earlier bioturbators had a huge impact.”

The researchers said that this realization was “the missing piece of the puzzle”, and to allow them to see changes due to these early life forms, they were then allowed to construct Earth’s mathematical model.

Dr. Benjamin Mills, also from Leeds University, who led this part of the research, said: “When we modeled our model, we were surprised by what we saw.

“The development of these small animals reduced oxygen to sea and atmosphere, but the levels of atmospheric carbon dioxide increased to such an extent that this resulted in global warming.

“We knew that there was warming at this point in the history of Earth, but it did not know that it can be powered by animals.”

This process further worsened the conditions for these animals, which potentially contributed to extinction events in the first 100 million years of animal development.

Professor Lenton, director of Exeter’s New Global Systems Institute, said, “There is an interesting parallel between the early animals that was bad for them, and what the human animals are doing for them now.” Developing a flexible solution for the challenges facing the world today.

“We are making a hot world with the expansion of Ocean Anoxia (deficiency of oxygen) which is bad for us and we share the planet with many other creatures.”
