In the year 1665 it was Huygens who had first perceived “an odd kind of sympathy” between two maritime clocks suspended side by side — a phenomenon we now refer to as “synchronization". The onset of synchronization or the emergence of particular phase relations between nonlinear oscillators has remained an object of deep fascination and scientific interest, ranging from neurobiology, electronics, to animal locomotion. Here, we will explore the diverse synchronization patterns of oscillating flagella (whip-like appendages akin to cilia) that are exhibited by species of algae. Performing a comparative study using organisms bearing few to many flagella, we reveal an unexpected dichotomy between active cellular control and passive hydrodynamics in the coordination of eukaryotic flagella.
