Fiber Technology Pushes Back Cognitive Milestones: Fiber technology is the ability to process and manipulate plant fibers into things like string, ropes, clothing, and nets. It represents a milestone in cognitive abilities and cultural progress, requiring not just dexterity but also a deep understanding of material properties. The brains needed for this technology had to […]
Homo habilis, one of the earliest known human ancestors, emerged around 2.3 million years ago with a brain size significantly larger than modern chimpanzees. By around 1.8 million years ago, they became the first species known to use toothpicks for dental hygiene, alongside their advanced tool use for specific tasks like skinning animals and cutting

30 Phil, Chapter 1 Touchstone 1 of 80: Big Bang. Immediately following the state of the singularity, the universe entered a phase of rapid expansion and cooling, known as the Big Bang Expansion. This critical period signifies not an explosion in space but the very expansion of space itself, from an incomprehensibly dense point known

A 30 Philosophers touchstone: Chapter 1, “Origin Story.” The universe began as an infinitely dense, unimaginably hot, and minuscule point known as a singularity. In a breathtaking instant, this singularity expanded and cooled, giving rise to the fabric of space, time, and matter, with all the laws of physics taking shape in that moment. The
First DNA Life: From chemical reactions before 4 billion years ago to replicating molecules about 4 billion years ago to DNA based life then to LUCA, the only DNA based branch to survive. Meaning, DNA based life likely started before LUCA, and LUCA is the only branch to survive the test of time. From LUCA
