When variations in Earth's orbit drive biological evolution

Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. They are responsible for half of the limestone produced in the oceans and therefore play a major role in the carbon cycle and in determining ocean chemistry. A team of scientists show that certain variations in Earth's orbit have influenced the evolution of coccolithophores.
