Dolphin drivel from Mail online:-
The Einsteins of the deep: Dolphins can perform feats of maths that would baffle human computer systems.
Dolphins can perform complex feats of maths that defy human computer systems. The finding has forced scientists to reevaluate how intelligent the animals are.
When hunting, dolphins blow 'bubble nets' - but are still able to use sonar - 'counting clicks' through the mass of bubbles. The ability seems to prove that the animals can do complex 'nonlinear' maths calculations. (*)
Human sonar systems would be baffled by the bubbles - but dolphins appear to have a mathematical ability to 'cancel them out. (**)
(*) No it doesn't, it may suggest they still use their sonar through their bubble nets. It doesn't prove they are doing calculations.
(**) No they appear to have the ability to cancel them out. The word mathematical is redundant, added for effect.
