Some fungus generate zombies and then take over their thoughts.
Ophiocordyceps, a tropical fungus, infects the central nerve systems of ants. After nine days in the insect bodies, the fungus gain total control over the host's motions. They drive the ants to climb trees before convulsing and falling into the cold, wet earth below, where fungus thrive. When the fungus arrives, it waits until exactly solar noon to induce the ant to bite a leaf and kill it.
