BFUT Paper 21 applies the CI formula to 100 species spanning the full range of biological complexity: viruses, bacteria, fungi, plants, invertebrates from sponges to cephalopods, vertebrates from fish to mammals, and humans.
The dataset is designed for comprehensive coverage and honest results, not to confirm prior intuitions about which species "should" rank highest.
The Rankings: Selected Species
At the floor: Viruses CI ≈ 1.0–1.2 — essentially at the gravitational minimum, as expected for entities without cellular metabolism or autonomous sensing. Bacteria CI ≈ 1.5–3.0 — above floor, electromagnetic channel access through chemotaxis.
Middle range: Insects CI ≈ 5–15 depending on species. Honeybees near the top of the insect range. Fish CI ≈ 15–35. Octopus CI₀ ≈ 45–55 — highest invertebrate, reflecting distributed nervous system, camouflage control, and problem-solving capability.
Upper range: Dogs CI ≈ 60–75. Chimpanzees CI₀ ≈ 95–110. Common ravens CI₀ ≈ 100–112. Bottlenose dolphins CI₀ ≈ 105–120. Human average CI₀ = 100, CI = 100 (since S = 1.0, CI₀ = CI for humans).
Dataset Integrity
30 species are consistency checks (N solved backwards from target CI to verify biological plausibility). 70 species are genuine out-of-sample predictions (all 13 parameters assigned independently, no adjustment). The 70 predictions are the scientific content of the dataset. Every result is independently checkable against the source paper's parameter table.
What Surprises
Cephalopods score substantially higher than their evolutionary distance from vertebrates suggests — because the formula is sensitive to connectivity and adaptive capacity, not absolute brain size. The formula is honest: it measures structural richness, not evolutionary pedigree. The results are falsifiable — anyone with the published parameters can recalculate any value.
