Master Timeline
All life today are either Prokaryote or Eukaryote. Around 2 billion years ago, Eukaryotes evolved from Prokaryotes. The evolutionary leap to eukaryotes introduced cells with a nucleus and membrane-bound organelles, a complex architecture derived from prokaryotic predecessors through endosymbiosis. This process, crucial for eukaryotic evolution, involved the incorporation of prokaryotic cells into the cytoplasm of […]

Prokaryotes are nucleus-free cells that include both bacteria and archaea — the two lineages that split shortly after LUCA.
76,000 Generations Ago Homo erectus is a direct ancestor of modern humans and represents a key point in human evolution where evidence of a truly omnivorous diet becomes clear, including the use of tools for hunting and processing both plant and animal foods. This species shows significant brain enlargement and other adaptations indicative of complex

By about 280 million years ago, Dimetrodon was one of the best-known predators of the Early Permian. It stalked rivers and floodplains alongside caseid synapsids, large amphibians like Eryops, and a landscape of Calamites, Sigillaria, ferns, and early seed plants.

Morganucodon is an example of a plant eater likely similar to our direct-line ancestors around this time. It is not a direct human ancestor but is among the early mammaliaforms, close to the lineage leading to true mammals.

30 Phil, Chapter 17, Alhazen, Touchstone 42: Senses. How we perceive an external world starts to become clear about 1020 CE. Since Alhazen and his pioneering work around 1020 CE, we have made significant advancements in understanding our senses. Our direct impressions of the world. Prior to Alhazen, most people on Earth believed in strange

It’s clear: neanderthals created art. The discovery of cave paintings in Spain, dated to over 64,000 years ago, marked a profound shift in our understanding of Neanderthals. This corrected the longstanding perception that Neanderthals lacked symbolic thought and artistic expression. To learn more, check out Beyond Human Bias: Reassessing Neanderthal Intelligence.

Invented by Newton in the 1660s (pub. 1687) and independently by Leibniz in the 1680s (pub. 1684). Both built on Galileo’s popularizing the idea of the infinitesimal. Calculus, the mathematical study of continuous change, introduced the concepts of differentiation and integration, providing tools to model and analyze motion, growth, and the infinitesimal. Newton, working primarily

From Baroque music and paintings to sculptures and archicture. The dawn of the 17th century witnessed the birth of the Baroque era, marking a transformative period in the history of art that spanned from circa 1600 to 1750 CE. Originating in Italy and spreading across Europe, the Baroque movement represented a significant evolution in artistic

In the vibrant intellectual climate of Ancient Greece, the 6th century BCE marks the embryonic stage of formal logic, attributed to the philosopher Thales of Miletus (around 624-546 BCE). Thales, recognized as the first of the Seven Sages of Greece, embarked on a quest that laid the foundational stones of logical thought. He shifted the

In 1975, Italian archaeologist Paolo Matthiae and his team unearthed the remarkable Library of Ebla at Tell Mardikh, Syria, revealing a trove of around 20,000 clay tablets and fragments. This discovery dramatically expanded our understanding of ancient Near Eastern civilizations, introducing Eblaite as a previously unknown Semitic language and providing unprecedented insights into the culture,

The library of Ebla, located in the ancient city of the same name was located in modern-day Syria. This library dates back to the 24th century BCE and contained thousands of clay tablets written in Sumerian and Eblaite,

First Brains: By about 520 million years ago, hunters roamed the seas. In the Cambrian explosion, a period of rapid evolutionary development that began around 541 million years ago, the earliest known animals with structures recognizable as brains made their debut in the Earth’s oceans. They possessed rudimentary beginnings central nervous systems, including a brain.

Geological and astronomical models predict that Earth is due for another glacial period within the next 100,000 years, possibly plunging much of the planet into ice. This event will significantly impact ecosystems, sea levels, and potentially human civilizations, depending on technological advancements and societal adaptations.
