Scientists keep finding more similarities between man and chimps . They share most of our factor , they seem to be able to manage tools , and they apprehend some English pretty well , too .
Now researcher have found that we share a similar brain pattern when commune .
Leslie is a 38-year-old female chimpanzee at the Yerkes National Primate Research Center.
Broca ’s area , located in the part of the human brain known as the inferior frontal gyrus , has been show to be critical for human manner of speaking and signal language . When a person speaks , or even contrive to say something , this region dismount up with activity .
" This is the first clock time someone has measured activity in that area in chimp nous , " said Jared Taglialatela , a life scientist at the Yerkes National Primate Research Center in Atlanta . " It look like a similarity betweenhumans and chimps . "
Taglialatela and his colleagues used a PET scan to image natural action in the brains of three chimps after doing two chore . In one , the Pan troglodytes necessitate for intellectual nourishment by gesticulate and vocalizing — making grunt and other haphazardness . In another they make it tilt out of their cages in exchange for food , as they had been teach to do before .
The scientists base that Broca ’s orbit was activated in the chimps ' brains after make gestures and vocalizing , but not after the stone undertaking , signalise that this learning ability region is peculiarly tied tocommunication .
The finding , reported online Feb. 28 in the journalCurrent Biology , narrows the spread between humans andchimpanzeesa little bit more .
" If we really desire to talk about the big differences between humans and Pan troglodytes — they ’re covered in hair and we ’re not , " Taglialatela toldLiveScience . " Their brains are about one - third the sizing of man ' . But the major differences come down to ones of degree , not of sort . "
He said we partake in many profound similitude with our closest brute relations . They have been indicate to possess noteworthy linguistic process capacity , to have the ability to make and use tools and even to ascertain behaviour from other members of their community — all traits once thought to be the hallmarks of humanity .
Chimps have been trained to use computing machine touch screen to pass along with humankind and can understand many words of spoken English .
They can also resolve introductory puzzles , sequence phone number in order , and , inone surprising study , beat college students on tests of short - terminus storage .
We even share most of ourDNA . Reportedly , the human and chimpanzee genome differ by only 1.5 to 5 percentage .
So what does break up us from apes ?
" I would really stress that the difference are just a affair of degree , " Taglialatela state . " There ’s some middling adept work with regards to Pan troglodytes make and using pecker in the state of nature , but of course it does n’t really liken to operating an MRI scanner . "
The same live on for voice communication , he suppose .
" Their English comprehension has been shown to be very advanced , but they could never have a conversation like we ’re having right now , " he say . " And recursiveness — the power to talk about language — is something I think is beyond the ability of Pan troglodytes . "
Taglialatela also said chimpanzee do not have the ego - control human race do . Where hoi polloi often ban their Book and activity to agree a societal situation , chimps generally play on impulse . If they are hungry , they will ask for intellectual nourishment ; if they are angry at another chimp , they might take a swat at him .
" They ’re not furred little humans , is what it comes down to , " he say . " But nonetheless , they ’re not so different . "
