Pre-hominid human evolution all the way back to LUCA.
Around 25 to 29 million years ago, Old World monkeys, including species like baboons and macaques, branched off from the common ancestor shared with apes. Unlike their ape cousins, Old World monkeys retained their tails and adapted to a wider range of habitats, from forests to savannas. Baboons, known for their ground-dwelling behavior, exhibit strong […]

The last surviving primate before the great apes! Gibbons are a “lesser ape” that branched off from our common ancestor with great apes. By this time, our ancestors had already lost their tails (like all apes) and were very agile in trees, using brachiation (arm-swinging) to move through the canopy. Gibbons are known for their

Laughter is closely related to emotional intelligence: The roots of laughter can be traced back to our common ancestors with other great apes, living around 10 to 15 million years ago. These early primates likely exhibited rudimentary forms of laughter as a social signal during play, much like modern-day chimpanzees, bonobos, and gorillas. This “animal
As hominins began to diverge from their great ape relatives around 2 to 4 million years ago, the simple vocalizations of their ancestors evolved into more sophisticated forms of communication. Among these was “human-like laughter,” characterized by its rhythmic structure, emotional depth, and social significance. Unlike the breathy panting of earlier primates, human laughter developed

Around 240 million years ago, during the late Triassic period, a crucial evolutionary development unfolded within the lineage that would give rise to mammals. It is believed that the XX/XY sex-determination system emerged in a common ancestor of mammals, possibly within the genus Therapsida, a group of synapsids that exhibited both reptilian and mammalian traits.

The movement of fluids, or circulation, evolved around 3.5 billion years ago in single-celled organisms to distribute nutrients and remove waste. Blood, a specialized fluid carrying nutrients and waste, evolved much later, around 1.2 billion years ago in multicellular organisms. It evolved to feed internal cells and carry away waste. As oxygen levels rose and
If Fuxi existed as one person, that person likely lived sometime between 8000 and 7000 BCE. Fuxi is a legendary figure in Chinese mythology, considered one of the Three Sovereigns. He is credited with creating humanity, inventing writing, and teaching people to fish and hunt. Fuxi’s contributions laid the foundation for early Chinese civilization and culture,
If Nüwa existed as one person, that person likely lived sometime between 8000 and 7000 BCE. Nüwa is a mother goddess in Chinese mythology, often associated with Fuxi. She is credited with creating mankind and repairing the pillar of heaven, symbolizing the restoration of order in the universe. Nüwa’s story highlights themes of creation, nurturing,
The Yellow Emperor, or Huangdi, is a legendary figure in Chinese history, traditionally credited with foundational contributions to Chinese civilization. He is associated with the development of the concept of Yin and Yang, the dualistic nature of reality, and balance, which profoundly influenced Chinese philosophy, medicine, and cosmology. Attributed to his era are the Huangdi

The Library of Ashurbanipal, established during the reign of Ashurbanipal (668–627 BCE), the last great king of the Neo-Assyrian Empire, is one of the most significant collections of ancient texts. Located in Nineveh, the capital of Assyria, this library housed thousands of clay tablets inscribed with cuneiform script, covering a wide range of subjects including

Charles Darwin, born on February 12, 1809, and passing on April 19, 1882, was an English naturalist whose groundbreaking work laid the foundation for the theory of evolution. His voyage on the HMS Beagle and the subsequent observations he made led him to formulate his theory of natural selection, published in his seminal work “On

Around 60 million years ago, the early ancestors of primates began to develop a crucial adaptation: the opposable thumb. This evolutionary milestone marked the beginning of increased dexterity and the ability to grasp objects more effectively. Living in the dense canopies of prehistoric forests, these early primates used their newly opposable thumbs to navigate their

Slightly greater range of movement and precision: Around 2 to 3 million years ago, the evolution of the human thumb reached a pivotal point. Early hominins, such as Australopithecus and later Homo habilis, exhibited a thumb that was more similar to that of modern humans. This thumb was capable of a greater range of movement

Likely between 25 and 30 million years ago, the evolution of the apes brought about further refinement of the opposable thumb. This period saw the divergence of the lineages that would lead to modern “lesser” apes like gibbons as well as later “great” apes, including orangutans, gorillas, and chimpanzees. The ape thumb evolved to become
General Relativity incorporated gravity into the mix. It describes gravity not as a force, but as the curvature of spacetime caused by massive objects. According to General Relativity, the curvature of spacetime around an object like the Earth causes objects to fall towards its center, which we experience as gravity. In November 1915, Einstein expanded

Special Relativity explains the relationship between space, time, mass, and energy. It shows that time and space are not separate entities but are connected as a single entity called spacetime. Additionally, it introduced the famous equation E=mc², which demonstrates that mass is engergy, energy is mass. They are equivalent and can be converted into each

In 1965, Arno Penzias and Robert Wilson, two radio astronomers at Bell Telephone Laboratories, stumbled upon a mysterious and persistent background noise that pervaded their radio telescope. After much investigation and the elimination of potential terrestrial and instrumental sources, they concluded that this noise was cosmic in origin. Their findings, published on May 20, 1965,

Simple wood tools starting with picking up a stick to poke at some out of reach fruit likely paralleled the use of stone tools. Wood tools for the most part did not survive the test of time. The earliest so far include advanced javelins form 400,000 years ago and a digging tool from 780,000 years ago.
Discovered in the 1990s, this 400,000-year-old Homo heidelbergensis structure in France is believed to be a primitive hut or shelter made from wooden posts and branches. The structure is thought to have been built by Homo heidelbergensis. The shelter is estimated to be around 4-5 meters (13-16 feet) wide and 6-7 meters (20-23 feet) long.
