Neanderthals were our closest human relatives , and they had many similarities with anatomically advanced human race .
But couldNeanderthalstalk ? Several pieces of grounds hint they could . But to answer this interrogative , first it ’s important to distinguish between speech and nomenclature .
Neanderthals may have had language, but not to the same advanced level that most modern humans exhibit today, some scientists argue.
Speech refers to the power toverballysay sound and words . Language is far more complex ; it meansusing those sounds to deal ideas .

Some research suggeststhat manner of speaking was produce long beforeHomo sapiensand Neanderthals separate in the evolutionary tree , sometimebetween 400,000 and 800,000 age ago .
" Before forward-looking human beings split from Neanderthals , the last common ancestor already possessed articulate speech,“Andrey Vyshedskiy , a neuroscientist at Boston University , narrate Live Science .
One of the most convincing pieces of evidence to support this theory is thatH. sapiensand Neanderthalsshare two evolutionary mutationsin a gene called FOXP2 . This cistron is associated with the ascendence of sinew in the mouth and face that help produce oral communication . mutant in FOXP2 can causelanguage deficitsin humans .
This suggests Neanderthals could make the movements tie in with manner of speaking , Vyshedskiy say . But what about language ?
By meditate forward-looking humans with linguistic process impairments , Vyshedskiy and fellow worker have proposed that homo evolved throughthree dissimilar nomenclature comprehension phenotypes . The most - advanced phenotype , which is what most hoi polloi have , is syntactic language . Syntactic language conveys complex narratives , uses possessive pronoun , and includes verb tense and spatial prepositions , he said .

A less - complex words comprehension phenotype , called qualifier language , include an sympathy of colors , sizes , and number . The least - complex speech comprehension phenotype involves only the inclusion of command , he said .
mastery lyric comprehension phenotype probably evolved earliest in our evolutionary history , soon after the human course break up from the chimpanzee linesix million years ago , he tell . Modifier spoken communication bit by bit develop 3 million age later , as humans started to fabricate I. F. Stone shaft , followed by syntactic language acquisitiona mere 70,000 year ago , he said .
" So Neanderthals were probable verbalise like us , but they had a modifier gene linguistic process phenotype , " he proposed . “ in effect , Neanderthals may have talk like a 3 - year - old child – well - articulated address , but no syntactic language comprehension ” , he said .
Some fossil research also supports the idea that Neanderthals had language . For object lesson , in a 2021 study in the journalNature Ecology & Evolution , research worker take eminent resolution CT CAT scan of the bones link up to hearing power . They determined that Neanderthals and modern world have a greater sensitiveness to some phone in the frequency range of spoken language than do other primates .
" There seems to be a convergence in hearing abilities between Neanderthals andHomo sapiensand presumably language ability as well,“Rolf Quam , a paleoanthropologist at Binghamton University in New York and carbon monoxide gas - author of the subject area , told Live Science . Because maintain sensory organs isenergetically costly , most creatures do n’t acquire sensorial abilities they do n’t practice . So if Neanderthals had a modern human audition rule , the theory goes , they likely could comprehend modern human talking to and , therefore , had some form of language , he say .
However , Quam recognise that there is some uncertainness about Neanderthals ' language power .
" Neanderthal language is one of the older questions in human evolutionary studies , " he enounce .
For instance , some fogy studies — such as those looking at thehyoid bonein the neck , which is ask in speech production — have been inconclusive , he pronounce .
Still , most experts would probably say Neanderthals had some lingual power , Quam say .
" At the very least , they [ Neanderthals ] had a communication system that was far more complex than [ that of ] any living imitator or primate species , " he said .
