Poster Abstract
The Institute for Creation Research (ICR) is experimentally testing an engineering-based model of rapid biological adaptation: Continuous Environmental Tracking (CET). This model infers that organisms actively track conditions within specific environments to self-adjust through internal mechanisms and initiate adaptive functionality. The animal under investigation is Astyanax mexicanus (Mexican tetra), a freshwater fish with well-differentiated, interfertile morphotypes: eyed surface-dwelling fish (surface fish) with distinct pigmentation patterns, and eyeless cave-dwelling fish (cavefish) with minimal pigmentation. Aquaria within our newly established laboratory contain breeding pairs of cavefish exposed to either (A) cyclical light/dark patterns of full-spectrum high-intensity light, (B) minimal light …
