1 E12 s

Encyclopedia : 1 : 1E : 1E1 : 1 E12 s

To help compare orders of magnitude of different times this page lists times between 32 000 years and 320 000 years (10¹² seconds—a terasecond—and 10¹³ seconds). See also times of other orders of magnitude

Shorter times
40 000 years -- time since the Cro-Magnon colonisation of Europe (Upper Paleolithic)
50 000 years -- age of Haplogroup B (mtDNA)
60 000 years -- approximate age of Haplogroup N (mtDNA), Haplogroup C (mtDNA) and Haplogroup A (mtDNA); out of Africa migration.
75 000 years -- time since the ancestors of the Indigenous Australians reached Australia
76 000 years -- half-life of nickel-59
80 000 years -- approximate age of Haplogroup M (mtDNA)
90 000 years -- approximate age of Y-chromosomal Adam
150 000 years -- approximate age of mitochondrial Eve
154 000 years -- half-life of neptunium-236
159 200 years -- half-life of uranium-233
160 000 years -- time since the Homo sapiens idaltu/Homo sapiens sapiens split
200 000 years -- approximate age of Homo sapiens
211 100 years -- half-life of technetium-99
250 000 years -- approximate age of Homo neanderthalensis
300 000 years -- time since Homo sapiens separated from Homo erectus (Middle Paleolithic)
301,000 years -- half-life of chlorine-36
