1 Full Tidbit.

Let’s explore a tidbit fully. This one is a Evolution Story.

From History:
Subject: Evolution.

Touch Emerges: Proto-Sensing.

800 Million Years Ago
Proto-Sensing.
  • Touch evolved long before brains..

So, to put it simply.

We process touch with our minds, but touch actually evolved long before brains. It was a big leap in sensing reality and it evolved in single-celled organisms.

Now for our main feature! The pithy version.

Long before the complexity of full-fledged nervous systems, elaborate senses, and brains, life on Earth developed the basic ability to perceive and react to mechanical stimuli—a process known as cellular mechanosensitivity.

Touch is the most fundamental form of information. Physical contact—pressure, vibration, movement—directly affects survival. Being able to respond to it required no complex processing, making it evolutionarily accessible very early in life’s history.
