What is the bronze and iron age?

  What is the bronze age? The bronze age that period, during which humans used weapons and implements made of bronze. It first began in the far east and maybe dated 5000-1200 BC in the middle east and about 2000-500 BC in Europe. The first part of the bronze age is also called ‘CALCOLITHIC’ or copper age since the translation from the stone age to the bronze age. A human could smelt copper but did not yet manufacture bronze. At around 2000 BC, tin was added to copper, to make bronze. What is the iron Age? The iron age is the period around 1200- 550 BC that followed by the bronze Age. When humans made weapons, tools, and farming implements of iron or steel. In Europe, it began around the eighth century BC and in the middle east, around the eleventh century BC.

From which species of the genus Homo have modern humans evolved? Modern humans, also called Homo sapiens sapiens (wise man), are a subspecies believed to have evolved from archaic Homo sapiens, who in turn evolved from Homo erectus. Archaic Homo sapiens typically include Homo heidelbergensis (Heidelberg man), Homo rhodesiensis (Rhoden Man), and Homo neanderthalensis (Neanderthal Man), because their brain size is very similar to modern humans. Archaic Homo sapiens are distinguished from modern humans by having a thick skull, prominent brow ridges, and the lack of a prominent chin. How old are the earliest fossils of modern humans? The earliest fossils of modern humans are from the middle Paleolithic period, about 200,000 years ago, such as from the Omo 1 site in Ethiopia. These fossils show the beginnings of the skull changes that we associate with modern people, including a rounded skull case and possibly a projecting chin.   Who are the cro-magnons?
