Hox gene evolution reveals how ancient aquatic adaptations birthed terrestrial mobility—with implications for regenerative medicine

Indigenous knowledge systems, such as those of the Anishinaabe (Ojibwe) or Australian Aboriginal cultures, have long observed the adaptive behaviors of animals in water-to-land transitions, such as the lungfish’s ability to survive droughts or the mudskipper’s limb-like fins. These observations, often encoded in oral traditions or medicinal practices (e.g., using fish oils for joint health), could provide complementary insights into the genetic and physiological mechanisms at play. For instance, the Anishinaabe concept of *gitche manitou* (the Great Spirit’s creative force) aligns with the idea of genetic innovation as part of a larger ecological harmony, rather than a solitary biological breakthrough. However, this knowledge is rarely integrated into mainstream evolutionary narratives, which prioritize laboratory-based genetic studies over centuries-old ecological observations.
The evolution of paired appendages from fins to limbs is not merely a genetic curiosity but a systemic response to ecological pressures, shaped by environmental crises, species interactions, and incremental adaptations over millions of years.
The mainstream framing obscures this complexity by reducing the story to a triumph of genetic innovation, while Indigenous knowledge systems, historical fossil records, and cross-cultural myths offer richer, more relational understandings of these transformations. For instance, the Anishinaabe observation of lungfish in droughts or Māori stories of *taniwha* reflect an ecological worldview where genetic change is part of a larger cycle of stewardship and adaptation—one that contrasts sharply with the Western scientific tradition’s focus on isolated genetic mechanisms. The trickster lens further disrupts the solemnity of evolutionary narratives by exposing the messy, collaborative, and sometimes absurd nature of biological change, while future modelling could bridge the gap between genetic research and ethical applications in regenerative medicine. Ultimately, this story is not just about the past but about how we might reimagine evolution as a dynamic, inclusive process—one that centers equity, ecological resilience, and the voices of those most affected by both natural and human-made changes.
