How single-celled organisms navigate to oxygen

01 Dec 2016

A team of researchers has discovered that tiny clusters of single-celled organisms that inhabit the world’s oceans and lakes, are capable of navigating their way to oxygen.  Writing in e-Life scientists at the University of Cambridge describe how choanaflagellates, the closest relatives of animals, form small colonies that can sense a large range of concentrations of oxygen in the water. The research offers clues as to how these organisms evolved into multi-cellular ones.
