Earliest known writing in Africa/Middle East zone. Human DNA today is the same as 50,000 BCE. There is no doubt there were many dozens and perhaps thousands of civilizations prior to the Sumer civilization, but Sumer is the earliest known, or at least the earliest well known. The Sumer civilization first established between 6500 and

7,000 Generations Ago All humans today share a single grandma, circa 175,000 BCE. We know this because all humans alive today share our ancestor’s haplogroup L genes — from our X chromosome. She was one of many thousands of women living in eastern Africa. Many maternal lines survived for many generations but ultimately over time
11,000 Generations Ago All humans today share a single grandpa, circa 275,000 BCE. We know this because all humans alive today share our ancestor’s haplogroup A genes — from our Y chromosome. He was one of many thousands of men living in eastern Africa. Many paternal lines survived for many generations but ultimately over time

2,400 Generations Ago The modern human DNA evolved sometime between 71,000 and 51,000 BCE. Imagine that. A human baby born today, and a human baby born in 60,000 BCE have nearly indistinguishable DNA. There are differences but essentially humans are the same now as they were then. The popular website 23andme.com focuses on 23 changes in
300,000 Generations Ago (from 2020 CE) Hominini Tribe: The last common ancestor with humans and the pan genus (chimpanzees and bonobos) lived around 7.5 mya. This branch of pan splits again about 1.5 mya into two species: chimpanzees and bonobos. Humans did not evolve from Chimpanzees, but both are the current evolution of a common
