Around this time, a round stone tower, now preserved to about 8.5 metres (28 ft) high and 8.5 metres (28 ft) in diameter is built in Jericho. [ 108 ] 8000 BC – 6000 BC: The post-glacial sea level rise decelerates, slowing the submersion of landmasses that had taken place over the previous 10,000 years.
The Neogene (/ ˈ n iː. ə dʒ iː n / NEE-ə-jeen, [6] [7]) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.04 million years ago to the beginning of the present Quaternary Period 2.58 million years ago.
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
Two species are described in the literature: A. ramidus, which lived about 4.4 million years ago [32] during the early Pliocene, and A. kadabba, dated to approximately 5.6 million years ago [33] (late Miocene). A. ramidus had a small brain, measuring between 300 and 350 cm 3.

It was initially thought these tools were made by Neanderthals, but a re-excavation between 2016 to 2022 also revealed human fossils for the first time, suggesting the artefacts were likely to ...
Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) [25] [26] [4] and was largely completed within 10–20 million years. [27] In June 2023, scientists reported evidence that the planet Earth may have formed in just three million years, much faster than the 10−100 million years thought earlier.
