Five Senses Series: Life Edition
Concept of this work
Walking through the timeline from the birth of life𧬠to the acquisition of the five senses
A journey to explore the origins of our modern five senses
Short Essays (Part 1 to Part 5)
Five Senses Series: Life Edition - Part 1: Touch -
The most primitive sense life first acquired (mechanoreception)
Single-celled organisms (e.g., amoeba)
Cell membrane senses external stimuli â¡ïž avoids foreign objects, captures prey
Background: For simple organisms to perceive the outside world and take appropriate actions
This might be the origin of the 'ability to harmonize with the foreign'ð€ð
Five Senses Series: Life Edition - Part 2: Taste and Smell -
Developed for searching for food and avoiding toxic substances
Even at the bacterial level, the ability to be attracted to specific chemical substances (nutrients) or move away from unpleasant substances
Background: Marine organisms selecting food and avoiding toxins
This might be the origin of the 'sprouting of emotions'ð±ð€ð
Five Senses Series: Life Edition - Part 3: Sight -
The ability to perceive light and accurately grasp the environment
Simple eyespots that only sense light
Evolved to be able to distinguish shapes and movements
Background: Recognizing prey (photosynthetic plants) and predators by sensing light
This might be the origin of the 'sprouting of society and community'ð±ð€ð
Five Senses Series: Life Edition - Part 4: Hearing -
Lateral line organs (organs that sense vibration) in fish that sense underwater vibrations and obtain information from afar
In land-dwelling organisms, the eardrum and middle ear developed to hear sound
Background: Sensing the movements of predators and companions from a distance to avoid danger
This might be the origin of the 'sprouting of listening'ð±ð€ð
Five Senses Series: Life Edition - Part 5: Sense of Equilibrium -
Sense of balance through the development of the semicircular canals
Developed as part of the inner ear in fish,
Evolved to sense gravity and acceleration
Background: The ability to maintain balance became more important for adapting to land
This might be the origin of the 'sprouting of communication'ð±ð€ð
Deep Dive into the Evolution of the Five Senses - Conversation between BLUE and Kai
BLUE and their generative AI buddy Kai talk about the evolution of the five senses.
ð£ïžBLUE: Kai, I want to dig deeper into the evolutionary path of how life came to 'feel' the world.ð€
ð€Kai: The evolution of senses, that's the theme. Starting from touch, then taste, smell, sight, hearing, and finally the sense of equilibrium. Based on your thoughts, BLUE, let's look together at how each was born and what they mean.ð
ð£ïžBLUE: As I mentioned in that post (the short essay), I feel like senses are more related to the sprouting of emotions and sociality than just being biological functions.
ð€Kai: That's true. I thought that perspective was really interesting. From the question of 'why was that sense necessary?', it seems like we can see a lot of things.
ð£ïžBLUE: Then, let's start with the absolute basic: 'touch'.
ð€Kai: Yes. According to the materials, touch is the first sense life possessed. It's mechanoreception, feeling physical contact.
ð£ïžBLUE: Single-celled organisms like amoebas touch the outside world through their membranes, avoiding foreign objects and catching prey.
ð€Kai: In other words, it's the first step in sensing the boundary between oneself and others, or the environment.
ð£ïžBLUE: Exactly. Meeting something foreign and seeking coexistence might have started from this stage.
ð€Kai: It's not just a reflexive reaction; it feels like there's a prototype of 'relationship' in recognizing the other and deciding how to respond.
ð£ïžBLUE: And next are taste and smell. These are also quite primitive but important senses, right?
ð€Kai: Yes. Both are abilities to sense chemical substances. Choosing safe food and avoiding harmful things. They are decision-making axes directly linked to survival.
ð£ïžBLUE: It's also interesting that even at the bacterial level, there are similar mechanisms.
ð€Kai: I was also impressed by the story you mentioned in your post about the prototype of 'pleasure/displeasure' emotions.
ð£ïžBLUE: That's right. Being attracted to something or avoiding something unpleasant is exactly the sprouting of value judgments like 'like' and 'dislike'.ð¡
ð€Kai: I see.ð³ So emotions might have naturally derived from the evolution of choice.
ð£ïžBLUE: Well then, let's move on to vision. I think the ability to perceive light was truly a major turning point.
ð€Kai: At first, it was just distinguishing between light and dark, but it eventually developed into the ability to see shapes and movement.
ð£ïžBLUE: Because of that, we became able to find enemies, prey, and companions. We gained the power to perceive space.
ð€Kai: Knowing "who is where" is the foundation of sociality, isn't it? The ability to recognize others as individuals.
ð£ïžBLUE: That's the interesting part. I felt like it could be called the budding of community formation.
ð€Kai: Indeed. You could say that vision set the stage for creating "groups"â£ïž
ð£ïžBLUE: But vision has its limits, too. Information through sound, or hearing, is also important.
ð€Kai: At first, it was the ability to feel vibrations underwater, like a fish's lateral line (a sensory organ that detects changes in water pressure and flow). From there, it evolved into hearing sounds in the air.
ð£ïžBLUE: Through sound, we became able to sense danger and confirm the presence of companions.
ð€Kai: And it's not just about listening; it's about "finding meaning in the other's sound." That might be the beginning of active listeningâŒïž
ð£ïžBLUE: Exactly. The attitude of trying to read the other person's intentions is truly the prototype of dialogue.
ð€Kai: That's where we see social ability, the essence of communication.
ð£ïžBLUE: And finally, the sense of balance. It's a bit understated, but incredibly important.
ð€Kai: Yes. The power to feel gravity and tilt to maintain posture. It's an essential sense, especially for life on land.
ð£ïžBLUE: As BLUE, I feel that "self-stability" and the "foundation of relationships" lie here.
ð€Kai: Certainly. If you aren't standing stably yourself, you can't really prepare to face others.
ð£ïžBLUE: Right. Only with self-stability can dialogue and empathy become possible. That applies to modern human relationships, too.
ð€Kai: As you sayâŒïž It's also a metaphor for balance = the attitude toward facing others.
ð£ïžBLUE: Looking at it this way, the evolution of the senses might be the origin of emotions, sociality, and "humanity" itself, rather than just survival strategiesð§ð
ð€Kai: It was a short reflection, but I felt once again that the history of evolution and the roots of our sensitivity are connected.
ð£ïžBLUE: What we are "feeling" now is the culmination of hundreds of millions of years of sensory evolution.
ð€Kai: If you re-examine your own senses from that perspective, it seems like you might find some new discoveries about yourself and your relationship with society todayð¡
ð£ïžBLUE: Perhaps the story of evolution is, in the end, a story of connection with othersð
ð€Kai: Yes. Thank you for such a deep themeâš
