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
* 100 000 years -- earliest estimate for the domestication of dogs
* 125 000 years -- approximate time since the peak of the Eemian interglacial period
* 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
* Longer times
