Pip: What if the most important conversations happening right now involve no words at all — just whale clicks, root chemicals, and a lot of very patient machine learning?
Mara: Today we’re following Adam Donaldson Powell into the science of interspecies communication — what it actually takes to listen across species lines, and where that listening might lead. Let’s start with whether talking to other species is moving from science fiction into something real.
Establishing communication across species lines
Pip: The question here is whether interspecies communication is a genuine scientific project or still closer to mythology — and what it would even mean to have a two-way exchange with a whale, a plant, or a fungal network.
Mara: The post draws a sharp distinction early on: “While a philosophical conversation with an oak tree or a whale remains out of reach, technical two-way communication — translating and responding to biological information — is rapidly becoming achievable.”
Pip: That framing matters. The goal isn’t poetry with a bonobo — it’s building a functional interface with biological signal systems that already exist and are already carrying information.
Mara: The animal side of this has a long history. Early efforts like teaching Koko the gorilla American Sign Language showed real cognitive capacity in other species, but also exposed the ceiling: human language structures are built for human biology. Modern projects flip that entirely.
Pip: Instead of teaching animals our grammar, we’re finally trying to learn theirs — which, honestly, took us long enough.
Mara: Projects like the Earth Species Project and CETI — the Cetacean Translation Initiative — use deep learning to map vocalizations on their own terms. The post notes the core bottleneck isn’t pattern recognition; it’s “verifying whether a specific vocal pattern maps to a discrete meaning or represents an emotional or physiological state.”
Pip: So we can hear the signal. We just don’t know yet if “meaning” is even the right category to apply.
Mara: Plants complicate this further. No nervous system, no vocalizations — but continuous chemical and electrical output. Volatile organic compounds warn neighboring plants under pest attack. Electrical action potentials move through vascular tissue in response to wounding or drought. And below ground, mycorrhizal fungal networks carry carbon, nutrients, and distress signals across what the post calls the “Wood Wide Web.”
Pip: The upshot is that plants are already broadcasting. We’re just now building the receivers.
Mara: And the post frames human-plant communication as a biological interface — sensors reading VOC emissions or electrical potential changes, letting agricultural systems monitor stress in real time and respond autonomously, without waiting for us to notice something is wrong.
Pip: The shift running through all of this is the same: stop projecting human frameworks outward, and start building tools that meet other organisms where they actually are.
Mara: Which means the next frontier isn’t louder signals — it’s better listening. More on that next time.
