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.

For thousands of years, writing had very little grammar. Grammar helps, and you should respect grammar, but serve the reader first.
Good journalism slows the spread of error by checking what happened, who said it, and what supports it.

The legendary story of Noah’s flood occurred in the year 2348 BCE if you believe Ussher’s biblical timeline he made up in 1654. However, this flood myth is clearly based on the Sumerian flood story documented in the Epoch of Gilgamesh circa 2100 BCE. The Epoch of Gilgamesh is regarded as one of the earliest
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
Stoicism is a philosophy of self-command centered on virtue while focusing your effort on what is yours to control.
Make goodness a normal part of your identity. Confucius taught that a better life begins when respect, duty, kindness, and self-discipline become normal habits.

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. Kingdom: Animalia > Phylum: Arthropoda > Class: Diplopoda (millipedes)

About 3.75 billion years lived LUCA. Not first life, but the common ancestor of all life today. LUCA used DNA, had ribosomes, used ATP, and had translation machinery. It lived in high-temperature environments.

Around 1.65 billion years ago, major eukaryotic lineages diverged, setting the ancestral paths that would eventually lead to plants, fungi, and animals.

The earliest known vertebrates originated about 530 million years ago during the Cambrian explosion. Domain: Eukaryota > Kingdom: Animalia > Phylum: Chordata
Around 470 million years ago, plants evolved a waxy cuticle to prevent water loss; only later did water-transporting vascular systems evolve.

Organisms that consist of more than one cell took several billion years to evolve from unicellular organisms. All species of animals, land plants and most fungi are multicellular, as well as many algae. A few organisms are partially both such as slime molds and social amoebae.

The earliest known life on Earth are fossilized microorganisms found in hydrothermal vent precipitates. Currently dated to about 3.42 billion BCE. These microorganisms were prokaryote cells. Single celled organisms with no nucleus and had early simple DNA. More complex DNA in a nucleus evolved about 1.5 billion years later in Eukaryotic cells, circa 2 billion

The earliest known man made glass dates back to circa 3500 BCE and to Egypt and Eastern Mesopotamia. Discovery of glassblowing around 1st century BC was a major breakthrough in glass making.
Starting in 1931 with the invention of the electron microscope, the nanoworld became visible to us. The nanoworld contains items as small in diameter as 1 micrometer (1 micron) to a diameter 1,000 times smaller, a diameter of 1 nanometer. The nanoworld includes the smallest single celled organisms, the smallest bacteria as well as viruses,
