An article published in the journal “Nature Communications” describes a research on the consequences of the evolution of the first animals on the Earth’s climate over 500 million years ago. A team of researchers investigated the consequences of the process called bioturbation, the reworking of soil and sediment by animals or plants, the cycles of phosphorus, oxygen and sulfur concluding that it led to a drop in oxygen in the seas and a global warming with various mass extinctions over the next 100 million years.
