A Timeline of Discoveries
While speculative, it is reasonable to position the occassional use of proto-medicine as emerging in the great apes sometime round 18 million years ago. Modern orangutans, apes, and chimpanzees treat wounds, digestive issues, and even use insect repellant. The Great Apes LCA lived around 18 million years ago, so using the Occam Approach, this implies […]

Discovered in 2016 in the Panama Canal area, Panamacebus transitus has been identified as the earliest known monkey to have reached the Americas, dating back approximately 21 million years. This find significantly alters our understanding of primate migration and geographical distribution during the Miocene epoch. This arrival in the Americas is a remarkable testament to

The ancient site of Çatalhöyük was not continuously known through historical records and was rediscovered in the modern era. It was first excavated by James Mellaart in 1958, who conducted major excavations between 1961 and 1965. These excavations revealed a wealth of information about Neolithic life and brought significant attention to the site. Its discovery

The earliest known use of plaster dates back to around 9000 BCE, with evidence from the ancient site of Çatalhöyük in modern-day Turkey. Here, Neolithic inhabitants utilized plaster made from lime to coat the floors, walls, and even ceilings of their mud-brick houses. This early application of plaster represents a significant technological innovation, indicating a
In the tropical rainforests of Mesoamerica, the ancient Olmecs unlock the secrets of the cacao pod. By fermenting, roasting, and grinding the seeds, they create the bitter beverage chocolate. This divine elixir lays the foundation for chocolate’s enduring legacy, cherished by the Mayans and Aztecs as a ceremonial drink, a currency, and a medicine.
In the highlands of Mexico, the story of maize, or corn, begins with its ancestor, teosinte. Through centuries of selective breeding, Indigenous peoples transform this humble grass into corn.
In the Neolithic villages of Poland, milk, a nourishing gift from domesticated animals, is left to curdle, giving rise to the earliest form of cheese.
The Ale of Progress: On the riverbanks of ancient Mesopotamia, Sumerians fermented grains into beer, a beverage derived from bread. It became a cornerstone of their civilization. It’s a drink for the gods, a nutritious staple, and perhaps the world’s first social lubricant.
The groundbreaking discovery that humans were making bread 14,000 years ago, before the advent of agriculture, was published in 2018. Since grain is easy to grow, does this suggest agriculture might have started a few thousand years earlier? Under study, but the discovery of bread-making from around 14,000 years ago indeed suggests that humans were experimenting

Since grain is easy to grow, does this suggest agriculture might have started a few thousand years earlier? Under study, but the discovery of bread-making from around 14,000 years ago indeed suggests that humans were experimenting with grains before the widespread adoption of agriculture, which is traditionally dated to about 12,000 years ago with the

In the lush, fertile lands of the Yangtze River Valley in ancient China, early inhabitants achieved a milestone that would revolutionize human society: the domestication of rice. Around 8,000 BCE, these innovative communities began to cultivate wild rice, laying the groundwork for sedentary agriculture and complex civilizations. This agricultural breakthrough not only provided a stable

How we perceive an external world starts to become clear. A 30 Philosophers touchstone: Chapter 17, “Alhazen and the Senses.” Since Alhazen and his pioneering work around 1020 CE, we have made significant advancements in understanding our senses and perceptions. Prior to Alhazen, most people on Earth believed in magical light-emitting-flashlight eyes.

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

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,

Hourglasses, also known as sandglasses or sand timers, were first used in the 14th century, although it is unclear exactly when they were invented. The earliest written reference to an hourglass dates back to the early 14th century in Europe, but they may have been used earlier in other parts of the world. Hourglasses were
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
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,
