Discovery of Giant Roaming Deep Sea Protist Provides New Perspective on Animal Evolution

AUSTIN, Texas — Groove-like tracks on the ocean floor made by giant deep-sea single-celled organisms could lead to new insights into the evolutionary origin of animals, says biologist Mikhail "Misha" Matz from The University of Texas at Austin. Matz and his colleagues recently discovered the grape-sized protists and their complex tracks on the oce...
