Underground #evolution: Study reveals how new #cavefish species emerged https://news.yale.edu/2026/05/21/underground-evolution-study-reveals-how-new-cavefish-species-emerged

Aquifer-mediated #speciation in cave-adapted fishes https://academic.oup.com/iob/advance-article/doi/10.1093/iob/obag021/8684975

"three species of Southern cavefish evolved from a common ancestor that had adapted to life #underground and dispersed through aquifers in soluble #subterranean rock formations. It provides the best evidence to date that speciation can occur in species adapted to only survive in subterranean ecosystems."
