The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant (AD/BC or CE/BCE) numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans shifted from a hunter-gatherer lifestyle to agriculture and fixed settlements.

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.
Archaeologists found 115,000-year-old human footprints where they shouldn't be—and they just might rewrite the history of human migration. ... [the era 130,000 to 80,000 years ago ...
“It appears suddenly in the fossil record of the Great Plains more than 4 million years after the extinction of all other North American primates, which occurred around 34 million years ago.”
“For cats, primary humans are adored, and spare humans are to be tolerated,” says the very spare human in this video. But just because you are not a cat’s favorite person doesn’t mean you ...
Cats and humans evolutionarily diverged from a common ancestor (boreoeutherian ancestor) approximately 80 million years ago, accumulating only 10–12 chromosomal translocations. [71] The order of eight genes on the cats' Y chromosome closely resembles that in humans. [72] Genes on X chromosomes of cats and humans are arranged in a similar way ...
Originally the Egyptian populations were credited with the early domestication of cats approximately 3,600 years ago but archaeological evidence also disputed the hypothesis in 2004. [2] In 2007, archaeologists working in Cyprus found an even older burial ground, a Neolithic site that is approximately 9,500 years old, of a child buried with a ...
