If we compare Earth’s history to a 24-hour day (with one second equaling 50,000 years),
Earth originates at midnight.
The earliest fossils were deposited at 5:45 A.M.
The first vertebrates appeared at 9:02 P.M.
The earliest mammals, at 10:45 P.M.
The earliest primates, at 11:43 P.M.
The earliest hominins, at 11:57 P.M.
And Homo sapiens arrives 36 seconds before midnight.
“The Society for Cultural Anthropology (a section of the American Anthropological Association) is excited to announce a groundbreaking publishing initiative. With the support of the AAA, the influential journal of the SCA, Cultural Anthropology, will become available open access, freely available to everyone in the world.”
