Publication: Animals set the direction for Earth’s carbon cycle

February 28, 2018Uncategorized

In a new paper led by Richard Boyle, we show that the emergence of animal ecosystems – and more specifically the animal burrowing and sediment mixing – acted to dampen the magnitude and duration of instabilities in the Earth’s long term carbon cycle. The paper is published in Geobiology.  Read the Rich’s comment on the … Read More

Why did it take so long before animals appeared on Earth?

August 28, 2017Uncategorized
