Modern humans, along with [[Cro-Magnon]] man, are more specifically classified as ''homo sapiens sapiens''.<ref>[http://www.historyworld.net/wrldhis/PlainTextHistories.asp?historyid=ab12 History of Homo sapiens] (History World)</ref>

''Homo sapiens'' was formerly known as ''homo sapiens sapiens'', and ''homo neandertalensis'' as ''homo sapiens neandertalensis'', because it was believed that they evolved from the hypothetical common ancestor ''homo sapiens''. Indeed they evolved from a common ancestor but it is now established that it was ''homo erectus'', so ''homo sapiens sapiens'' became just ''homo sapiens'' and ''homo sapiens neandertalensis'' became just ''homo neandertalensis''.

Humans inhabit every continent including [[Antarctica]], with a total population of over 6.5 billion as of 2007.
