Description: TED Fellow Prosanta Chakrabarty raziskuje skrite dele sveta v iskanju novih vrst rib, ki živijo v jamah. Te podzemne ribe so razvile neverjetne adaptacije in nam dajejo biološki uvid v slepoto in geološke sledi o premikanju kontinentov pred milijon leti. Premišljujte o davnih časih v tem kratkem govoru.

Blind cavefish hold clues to both the evolution of vision and the shifting of continents over millions of years. Some species in Madagascar are more closely related to fish in Australia than to those nearby, evidence that continents moved rather than the fish themselves. The genetic adaptations in these species even help scientists understand how blindness develops. Rapid habitat loss threatens these rare creatures, sometimes before their closest relatives are even discovered.
