Michael Levin: Behavioral Science in Developmental Biology & Bioengineering

The Unreasonable Effectiveness of Behavioral Sciences

• 💡 Professor Michael Levin argues that behavioral sciences are fundamentally important to developmental biology, bioengineering, and biomedicine, challenging the traditional hierarchy of scientific disciplines.
• 🧠 He suggests that the mind-body problem is central to developmental biology, as organisms transition smoothly from simple matter to complex minds, blurring disciplinary boundaries.
• 🎯 The goal is to create a framework for recognizing, creating, and ethically interacting with diverse intelligences, from familiar creatures to synthetic life forms and AIs.

Redefining Intelligence and Biological Systems

• 🔑 Levin proposes that cognition is a broader category than life, with living systems defined by their ability to expand the "cognitive light cone" of their parts and achieve larger goal states.
• 🔬 Biological systems possess a multiscale competency architecture, where intelligence operates across various spaces like transcriptional, physiological, and anatomical morphospace, not just 3D movement.
• ✅ Intelligence is characterized by the ability to reach the same goal through different means, a concept emphasized by William James, which is empirically testable in biological systems.

Bioelectricity: A Key to Morphogenesis

• ⚡ Bioelectricity, mediated by ion channels and gap junctions, serves as a fundamental communication system within cells and tissues, encoding anatomical patterns.
• 🧬 Unlike genetic determinism, bioelectric patterns are rewritable memories that guide morphogenesis, allowing for flexible and goal-directed development.
• 🛠️ Tools from neuroscience, such as neuropharmacology and optogenetics, can manipulate these electrical states to reprogram cellular behavior and tissue formation.

Reprogramming Form and Function

• 🌱 By manipulating bioelectric signals, researchers can induce the formation of complex structures like ectopic eyes in tadpoles, demonstrating modular and self-organizing capabilities.
• 🔄 Planarian worms can be reprogrammed to grow multiple heads or even heads of other species by altering their bioelectric pattern memories, highlighting the plasticity of biological form.
• 🛡️ Bioelectric control can also suppress cancer formation by forcing electrically disconnected cells to maintain connection with the collective, overriding oncogene expression.

Novel Beings and Embodied AI

• 🚀 Anthrobots, self-assembled from human tracheal cells, exhibit motility and repair neural defects, demonstrating inherent plasticity and capabilities not directly evolved.
• 🤖 The Mambot robot scientist platform explores morphospace by generating hypotheses about cellular signals, conducting experiments, and learning, acting as an embodied AI navigating anatomical possibilities.
• 🌐 This research aims to develop an anatomical compiler to specify arbitrary biological forms and to facilitate communication with unconventional minds, including future synthetic organisms.
