ENCODE Project's "80% Functional Genome" Claim (2012)

The ENCODE Project's bold 2012 declaration that 80% of the human genome is biochemically functional directly challenged decades of junk DNA dogma, triggering a firestorm among evolutionary biologists. Dan Graur's rebuttal highlighted that the claimed 80% figure conflates any molecular activity with evolutionary function, arguing that only 10.7% of the genome shows clear constraint—a gap that remains unresolved.
