6000 BC: Evidence of habitation at the current site of Aleppo dates to about c. 8,000 years ago, although excavations at Tell Qaramel, 25 kilometres (16 mi) north of the city show the area was inhabited about 13,000 years ago, [124] Carbon-14 dating at Tell Ramad, on the outskirts of Damascus, suggests that the site may have been occupied since ...
Layers dating from between 250,000 and 140,000 years ago in the same cave contained tools of the Levallois type which could put the date of the first migration even earlier if the tools can be associated with the modern human jawbone finds.

Patrilineal and matrilineal most recent common ancestors (MRCAs) of living humans roughly between 200 and 100 kya [56] [57] with some estimates on the patrilineal MRCA somewhat higher, ranging up to 250 to 500 kya. [58] 160,000 years ago, Homo sapiens idaltu in the Awash River Valley (near present-day Herto village, Ethiopia) practiced ...
The study states that the deep split-time estimation of 350 to 260 thousand years ago is consistent with the archaeological estimate for the onset of the Middle Stone Age across sub-Saharan Africa and coincides with archaic H. sapiens in southern Africa represented by, for example, the Florisbad skull dating to 259 (± 35) thousand years ago.

Buckland, like others at the time, did not grasp how long ago dinosaurs lived, believing Earth to be only a few thousand years old. Scientists now know Earth is about 4.5 billion years old ...
Depending on the continent, the era generally falls between the years AD 200–600 and AD 1200–1500. The major classical civilizations that the era follows are Han China (ending in 220), the Western Roman Empire (in 476), the Gupta Empire (in the 550s), and the Sasanian Empire (in 651). Middle Ages – Lasted from the 5th to the 15th century.
From roughly 230-200 million years ago, during the Late Triassic and into the early Jurassic periods, dinosaurs emerged from just one of many reptilian species to become the dominant species on Earth.
Amidst much speculation, the team opened it to find a message from another archaeologist digging at the site—200 years ago. The archaeologist was the first to explore the ancient location, and ...
