Homo sapiens
Homo Sapien. More recently, many scientists have classified modern humans as Homo Sapiens Sapiens.
They didn't have a language. The earliest language scientists have defined was developed in a Homo sapiens species.
There is no concensus among scientists one which species first used spoken language. Many believe that Homo Sapiens and Homo Neanderthalensis were the ONLY two species to use language.
They did and do: Greek, Latin, Sanskrit, Hebrew, English, French, Italian, Mandarin, Hindi, Urdu, Swedish,.... Homo sapiens is our species. We are Homo sapiens.
The two subspecies are Homo sapiens idaltu (which is thought extinct) and Homo sapiens sapiens. Some sources show Neanderthals (Homo neanderthalensis) as a subspecies (Homo sapiens neanderthalensis).Similarly, the discovered specimens of the Homo rhodesiensis species have been classified by some as a subspecies (Homo sapiens rhodesiensis), but these last two subspecies classifications are not widely accepted by scientists.
yes they did and with that macarroni and cheese was developed
No they did not. The earliest discovery of language which allowed symbolic beliefs were developed in homo-sapiens not Australopithecus.
Where they came from
The genus that includes modern humans is Homo.
Homo sapiens are modern Humans. When we first evolved, we were unique among other primate in that we had the ability to use language and innovate.
