12,000 Generations Ago Neanderthals and Denisovans had a common ancestor about 300,000 BCE (current estimates range from 250,000 to 500,000 BCE and possibly as far back as 1.3 million BCE). Humans did not evolve from Denisovans nor Neanderthals, but both were the evolution descendant of a common ancestor with Homo Sapiens tentatively identified as Homo …
The Xia Dynasty is the first documented government of ancient China. The first to adopt dynastic succession. In modern times, it was regarded as a myth created later by Chinese historians, but 20th-century excavations uncovered sites which corresponded to descriptions in earlier historians’ accounts. This fact is an important lesson on understanding how little survived …
The Greek philosopher and mathematician Pythagoras was born in Ancient Greece on the island Samos which is about a mile off the coast of modern Turkey. History looks at Pythagoras as an educator and philosopher as well as a cult leader. He discovered the musical octave, used deductive reasoning, and embraced an early version of …
Augustine is known as the father of Western religious scholarship. He reconciled the science and philosophy of Aristotle with church beliefs. Contrary to modern racists who portray Augustine as a white man, Augustine was a North African black man. That fact is sure to make the racist religious right’s heads explode! My favorite translated Augustine …
The Greeks knew the Earth is spherical. For example, Pythagoras (570-495 BCE), Aristotle (384-322 BCE), and Euclid (circa 450 BCE) wrote about the Earth as a sphere. Eratosthenes (276-194 BCE) even calculated the circumference of the Earth to within 1%. He also wrote about the idea that India could be reached by sailing westward from …
Socrates was a Greek philosopher and is frequently credited as the founder of Western philosophy. He left no writings, but his student Plato documented his philosophy.

155 Generations Ago The Proto-Sinaitic alphabet is considered the earliest trace of alphabetic writing and the common ancestor of both Ancient South Arabian script and the Phoenician alphabet. The ancient South Arabian script evolved about 900 BCE which continued to evolve into today’s Modern South Arabian languages. The Phoenician alphabet evolved into the Greek alphabet …
133 Generations Ago The Phoenician alphabet is a direct continuation of the Proto-Canaanite script circa 1300 BCE. Starting about 900 BCE, the Phoenician alphabet thrived and was adapted by others. It evolved into use by many languages including Greek, Old Italic and Anatolian scripts. These early uses of the alphabet evolved into the alphanumeric alphabet.Â
40 Generations Ago Spaces between words started circa 1000 CE because those copying texts found it easier and faster to copy if they introduced spaces between words. The 1215 Magna Carta is a good example of this quality of writing which included word-spacing, uppercase, and lowercase, but no punctuation, nor paragraphs.Â
50 Generations Ago Uppercase and lowercase started circa 800 CE. Notice in the image above of an actual book from 460 CE that although it is missing word-spacing, punctuation, paragraphs, and lowercase it does make use of two colored text as well as margin notes to orient the reader. Many pre-printing press books very well …
The Twelve Tables were rules citizens had to follow, and limits on the powers of the government. This idea was used several times during Roman history to force the Patricians, aristocrats, to consider the views of the plebeian citizens, commoners.

The Sumer civilization first established between 6500 and 4100 BCE. We know quite a bit about …
Some of my favorite translated meditations include: Learn to be indifferent to what makes no difference. The happiness of your life depends upon the quality of your thoughts.

Some of my favorite translated sayings are: The man who knows he can, and the man who knows he cannot, are both correct. Real knowledge is to know the extent …
The millipede Pneumodesmus newmani is the oldest air-breathing animal known to date. This ancient denizen of the Scottish waters once roamed the Earth during the early Silurian era. The millipede likely supplemented its oxygen intake through air as well as using its gills while in water.  Â
The last universal common ancestor (LUCA) is estimated to have lived approximately 3.5 to 3.8 billion years ago. It is the organism from which all current life on Earth descended from. Your greatest grandparents. Although no LUCA fossils have yet been found, geneticists can study LUCA by analyzing the genetic information of its descendants. LUCA’s …
