This was because the inside of the boyвЂ™s fossilised skull showed an impression from a part of the brain known as BrocaвЂ™s Area. It was initially believed that the вЂTurkana BoyвЂ™, and members of his species, Homo ergaster, were capable of language. Probably had advanced communication skills and the capability to produce some simple words and communicate to a greater degree than is seen in our closest living relatives, the chimpanzees.Д®vidence for this species language ability comes from their fossilised skeletons and from detailed analysis of their tool technology. LucyвЂ™s brain was similar in size and structure to a chimpanzeeвЂ™s so she may have been able to use simple protolanguage.Дate: 1.5 -1.9 million years ago Lived: Africa, possibly migrated out into regions of the Middle East and Asia Language ability: limited speech and language ability. This has been called вЂprotolanguageвЂ™ because it lacks the syntax and grammar of modern language. Language is more than just speech and experiments with chimpanzees show that they are able to learn and understand simple sign language. LucyвЂ™s relatively narrow spinal cord compared to modern humans indicates that she lacked the nerves responsible for this fine control of the muscles that co-ordinate breathing during speech. The speech of modern humans requires a complex co-ordination of breathing muscles in order to vary pitch and produce long sentences. LucyвЂ™s sound range would probably have been restricted in the same way. This limits the range of sounds that they are able to produce.

Chimpanzees, for instance, have a vocal tract with a high larynx and a short pharynx. This indicates that she, and others of her species Australopithecus afarensis, had an ape-like vocal tract. The base of LucyвЂ™s skull was ape-like in shape. It is likely however, that communication was very important and they may have been as vocal as modern chimpanzees. This evidence is seen to indicate an increasing ability for language and speech over time.Дate: 2.8 to 3.9 million years ago Where lived: eastern Africa Language ability: commonly thought to have no language or speech abilities. Certain physical features associated with spoken language, such as the position of the vocal tract, the structure of the brain and the size of the spinal cord, gradually evolved into the modern human form. Much of this evidence appears only in the last 40,000 years and includes the manufacture of highly complex tools, the production of symbolic art and the existence of widespread trade systems.Д«y contrast, those who claim language evolved slowly base their argument on skeletal remains and the evidence of structures related to speech production. Those who support a sudden development of language focus on archaeological evidence of behaviour that could be connected to language use. Others claim language evolved slowly over the last 2 million years and was not restricted to our own species. There are two main views вЂ“ some scientists believe language appeared suddenly, and is limited to our own species. This has led to continued debates as to when language evolved. Because language can not вЂfossiliseвЂ™, scientists have to rely on purely circumstantial evidence when trying to determine the language and speech capabilities of our ancient ancestors.
