"Tsis xav hais tias lawv hais tias:" saib lub ntiaj teb no nyob hauv liab dawb. Qhov no txhais tau hais tias lub ntsiab tob tob psychophysiological. Ib qho chaw tshwj xeeb hauv kab no yog nyob ntawm tsom iav-chameleons. Qhov no yog ib hom kev zoo tshaj plaws rau sab nrauv sab nrauv thiab sab hauv tsev. Raws li txoj cai, chameleons yog ua los ntawm quartz iav nrog ntxiv ntawm tshwj xeeb photochromes, uas tsaus ntuj nyob rau hauv lub teeb ci.
