It's not merely sensing heat, but sensing weakly radiating heat from a distance. The human researchers could only distinguish the test and control objects by touching them.
Did you actually read the article?
- dx87 7y agoAll the article says is that the nose of dogs is much more sensitive to heat than other animals, calling it a "new sense" is an exaggeration.
- ebg13 7y agoHumans also sense radiative heat from a distance. The only difference explicitly stated in the article is degree of sensitivity not a new sense.
- sombremesa 7y agoBut it can be a nuisance.
- wintermutesGhst 7y agoI think degree of sensitivity, discrimination, or directionality can warrant counting a 'new sense'. I would consider my sense of thermoreception to be different from that of a snake's heat-pits, or hearing to be a different sense from feeling vibrations.
- frandroid 7y agoAs the article about epistemology posted yesterday mentioned, at some point, a difference in degree becomes a difference in kind.
