The Venus Tablet of Ammi-Saduqa. Nineveh, Mesopotamia: A Sumerian scribe records the movements of the stars, including Venus, on a clay tablet. It depicts the conjunction between Venus and the Sun during the reign of Ammi-Saduqa. This document is important because it demonstrates that the

At 65 years old, Malalael fathered Jared; Malalael lived another 830 years and fathered other sons and daughters.

The first carrot crops. They are from Afghanistan and purple (the orange variety is a cross bred in Holland in the 16th century).
3700 BC
Mesopotamia. First evidence of state organization, which generally involved a complex social structure and the maintenance of an army. In Mesoamerica, this transition occurred around 300 BC, in the Andes, China, and Southeast Asia around the 1st century BC, and in West Africa around the
5000 BC approx.
Livestock farming begins in the Tanzania, Kenya, and Sudan area; at the same time, the lactose tolerance genetic mutation spreads.
5000 BC approx.
The first blacksmiths used the ancient method of trial and error to forge the first copper objects and weapons. The Egyptian pyramids are an example of what copper makes possible. To forge the 300,000 chisels needed to work the stones that would form the pyramids,
5000 BC approx.
genetic mutation in populations of Tanzania, Kenya, and Sudan gives rise to the most common variant of lactose tolerance (i.e., our ability to digest milk even as adults).
5000 – 3000 BC
In Lower Mesopotamia, the transition from village communities to urban societies.

New Guinea. First independent emergence of agriculture. It is therefore one of the world’s earliest uses of agriculture. However, there are some severe limitations that prevent the local populations from developing like other Eurasian populations such as the Mesopotamians, Europeans, and Chinese. These are: the

Eastern slopes of the Central Ural Mountains. The “Great Idol” is erected: a 5-meter-high totem pole decorated with elaborate carvings. It is recovered from a peat bog on Lake Sigirskoye. We know very little about the social and political systems of these prehistoric communities, but
8000 – 2500 BC
The domestication of certain animal species makes a difference in different societies. The Major Five are: sheep, goat, cow, pig, and horse. The Minor Nine are: one- and two-humped camel, llama, donkey, reindeer, buffalo, yak, Bali cattle, and mithan. Others will follow many centuries later:

In an article in “Science,” Charles Hockett demonstrates that the soft “f” and “v” sounds, previously thought to be more common among cultures that ate softer foods, evolved in the early Neloitic, thanks to a particular conformation of the mouth, jaw, and upper teeth. Hockett
10,000 – 9,000 BC
Southwestern Turkey, western Iran, and the Levant (present-day Lebanon and Syria). First permanent settlements of farmers and herders. The first domesticated species were wheat and goats.
10,000 BC
Barents Sea, between present-day Norway and Russia. On the seabed, large-scale explosions of cold methane pockets occur. These pockets remained trapped there as ice for millennia and are now being released due to global warming. This contributes to a further strong greenhouse effect.
10,000 BC – 8,500 BC
In Talal, northern Chile, the Huentelauquen people have been extracting 700 cubic meters and 2,000 tons of rock from a local mine continuously for over 1,000 years.
12,000 BC
Alaska. The first clear and undisputed evidence of the presence of human villages on the American continent. Colonization, however, likely began much earlier. In the few centuries that followed, hundreds of additional settlements are known to have taken place in the present-day United States and
14,000 BC – 300 BC
Japan. The monolithic Jomon culture dominates over ten thousand years of foraging history: from 14,000 BC to 300 BC, spanning long periods preceding the advent of rice cultivation in Japan. It is documented by thousands of archaeological sites, discovered primarily in the late 20th and
14,000 BC
Tultepec, Mexico. In 2019 AD, archaeologists discovered enormous traps containing the remains of at least 14 mammoths. The traps date back approximately 16,000 years. During 10 months of excavation at the site, which was intended to become a landfill, 824 bones have been found so

The arrival of humans in Europe caused the extinction of half the species of large mammals: mammoths, rhinoceroses, hyenas, lions, panthers, bears, moose, etc.

Phlegraean Fields, Campania. Eruption of the Campanian Ignimbrite. The Campanian Ignimbrite is the product of the largest explosive eruption in the Mediterranean region in the last 200,000 years. This eruption, which occurred in a center located in the Phlegraean Fields, buried much of Campania under

Neanderthals kissed with Homo sapiens and, between one escapade and another, they (self-)medicated, and some were predominantly vegetarian. Through the sequencing of traces of ancient DNA found in five dental plaque samples, we can see that the diet of their cousin Neanderthals was very varied:
47,000 – 35,000 BC
Aurignacian: Paleolithic culture widespread in Southern Europe and present-day Israel. It left behind the first artifacts representing rudimentary lunar calendars.
50,000 BC
Humanity’s Great Leap Forward. In East Africa, the Near East, and Southeastern Europe, and subsequently in Southwestern Europe, evidence is accumulating of multi-piece weapons such as bows and arrows, complex tools such as nets and ropes that allowed the addition of fish to the diet,

The Australian Aborigines (or what are now called such) first reached Australia from the Indonesian islands. Even from the closest islands to Australia (Timor and Tanimbar), the new continent is invisible on the horizon, even considering the decline in sea levels due to glaciations. The
