Cilia and the Antenna

Cilia and the antenna (Cilia you're breaking my heart)

"On the surface of nearly every cell in the body is a slender protuberance called the primary cilium. Although ubiquitous, the primary cilium was long considered—with a few exceptions—to be a largely useless evolutionary vestige, destined to go the way of the tailbone and the wisdom tooth. But now we know that cilia are functioning organelles, essential to normal development and health.
Some cilia are rigid spikes that act as antennae, gathering sensory information for the cell from the surrounding environment. Other cilia are flexible and whip-like, capable of registering the surrounding fluid's flow and ebb. (Mary Beth Gardiner)"

"An analogy for our artificial sensory
system in the animal world would be the cellular
cilia, insect antennae, as well as the specialized
sensory hairs of mammalian whiskers."

We see the implementation of (infrared) light sensing at different levels of reality (eg. the world of the cell, the world of Nature and the world of Humanity).
