The scaly whiskery dragon is the first reptile to show it can imitate a match , and all for the price of a mealworm , new research intimate .
In a new study , researchers trained a 3 - year - old femalebearded dragon(Pogona vitticeps ) how to open a skid filmdom door with her head . Once successful , the lizard move into the door and run through a mealworm prize . Other bearded dragon then watched a video of the lizard enter the door , and scientists monitor whether the other beast imitate the behavior .
Bearded dragons are the first known reptiles that can imitate each other, a study finds.
All eight bearded dragons that watched the 11 - second television of the sales demonstrator lounge lizard followed suit . They opened the threshold in exactly the same manner as the bearded dragon in the video did , the investigator said . In direct contrast , the four lizard that did not see the video recording run out to launch the door . [ The 5 Smartest Non - Primates on the Planet ]
" The ability to study through imitation is think to be the tiptop of societal acquisition and long considered a distinctive characteristic of humans , " lead investigator Anna Wilkinson , a senior lecturer of animal cognition at the University of Lincoln , in the United Kingdom , say in a statement . " However , nothing is known about these abilities in reptilian . "
It ’s unconvincing that the successful lizards were shew spontaneous conduct , as they all launch the door in the same way as shown in the TV , Wilkinson said . Their behavior suggests that they were imitating the demonstrator lizard to get to the mealworm .
" This inquiry suggests that the bearded Draco is capable of societal learning that can not be explained by elementary mechanisms — such as an individual being pull to a sure location because they observed another in that location or through experimental acquisition , " Wilkinson allege . " The determination is not compatible with the claim that only humans — and to a lesser extent , great ape — are able to simulate . "
Scientists previously opine only humans and advanced primates , such as chimpanzees , could copy one another . on-key impersonation is a complex deportment ; it requires that an animalcopy the deportment of anotherand empathise the significance behind it . This is different from emulation , in which an animal copies a conduct without empathize its implications . For instance , a parrot might repeat a phrase , but not pull in what it ’s saying .
late research , however , shows that impersonation may be more common that previously thought . Apes , such as wild chimpanzees , Gorilla gorilla and orang , imitate each other , as can monkeys , including wild marmoset and rhesus macaques . chick , such as pigeons and zebra finch , and other mammals have also join the order . mime mammalian let in dogs , bottlenose dolphin and the band mongoose .
This is n’t Wilkinson ’s first foray into the globe of reptilian knowledge . in the first place this year , she and her colleagues showed that turtles couldlearn how to use a touch - screen computer .
Reptiles and mammal share a common ancestor , and understand the behavioural similarities and differences between the two groups of beast may help oneself researcher ride apart the organic evolution of cognition , Wilkinson order . It ’s probable that the ability to imitate is ground on ancient mechanisms , she added .
" These results reveal the first evidence of imitation in a reptile species and advise that reptiles can use social information to learn through imitation , " she said .
The study was put out online Sept. 9 in thejournal Animal Cognition .
