5-2 million years ago: Hominids shift away from the consumption of nuts and berries to begin the consumption of meat. [1] [2] A hearth with cooking utensils. 2.5-1.8 million years ago: The discovery of the use of fire may have created a sense of sharing as a group. Earliest estimate for invention of cooking, by phylogenetic analysis. [3]
7000 BC – agriculture had reached southern Europe with evidence of emmer and einkorn wheat, barley, sheep, goats, and pigs suggest that a food producing economy is adopted in Greece and the Aegean. 7000 BC – Cultivation of wheat, sesame, barley, and eggplant in Mehrgarh (modern day Pakistan).
This is a list of such named time periods as defined in various fields of study. These can be divided broadly into prehistorical periods and historical periods (when written records began to be kept).

The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). [3]

About ten thousand years ago, humans in the Fertile Crescent of the Middle East develop agriculture. Plant domestication begins with cultivation of Neolithic founder crops. This process of food production, coupled later with the domestication of animals caused a massive increase in human population that has continued to the present.
The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, [7] [8] [9] during the Eoarchean Era, after a geological crust started to solidify following the earlier molten Hadean eon. There are microbial mat fossils such as stromatolites found in 3.48 billion-year-old sandstone discovered in Western Australia.
