Idea 1.

A Medieval FAQ.

Yes—and no. The Fermi Paradox remains a useful framework for discussing the possibility of extraterrestrial life, encouraging us to consider the probabilities and challenges of making contact. It’s a great starting point for exploring the vastness of the universe and our role within it. However, its implied conclusion—that we “should have” seen signs of intelligent life by now—is fatally flawed. This assumption oversimplifies the complexities of interstellar communication and the nature of alien civilizations.

First, the universe is unimaginably vast, and humans have only been broadcasting detectable signals for about a century. These signals have barely traveled 100 light-years in a universe that spans billions of light-years. Expecting contact already assumes that advanced alien civilizations exist within this tiny range, are actively listening, and would prioritize responding to us. It’s more likely that we are in the very early stages of the search, my TST Futurism Timeline puts first contact at about the year 2325, plus or minus a century.

Second, the Paradox often overlooks that alien civilizations might not think or act anything like us. They are not simply advanced humans; their evolution, priorities, and technologies could be incomprehensibly different. To them, humanity might be unremarkable, akin to how we view ants, interesting but not a priority. This anthropocentric bias reveals more about our assumptions than it does about the likelihood of extraterrestrial life.

Idea 2.

A Medieval FAQ.

Why bipedalism?

First, this came about from the following Facebook comment:

My only doubt is the transformation from monkeys. Why would we want to stand erect when we had the ability to climb to reach food in trees?

Answer: Understanding evolution is key, and it’s not a matter of “want.” It’s a series of fortunate accidents—small genetic changes that offer advantages to offspring. Around three to five million years ago, our ancestors, most likely by the genus Australopithecus, began walking upright. Walking upright provided several benefits, such as freeing the hands for carrying tools and food. Bipedalism is also more energy-efficient for long-distance travel, which was crucial as our ancestors moved from trees to open environments. Moreover, standing upright allowed them to see over tall grasses to spot predators and navigate effectively. These combined factors made bipedalism a successful adaptation for our ancestors, aiding in their survival and evolution.

Understanding the evolutionary shift to bipedalism provides you with wisdom about your past, illuminating the context of your journey and the nature of human adaptation.

How did it start? Several theories explain why great apes began walking upright. One theory suggests that bipedalism evolved because it is more energy-efficient than “knuckle-walking.” Another idea is that walking on two legs freed up hands for tasks like gathering food. Some scientists believe it was part of a mutually beneficial arrangement where males gathered food for females and their young in return for exclusive mating. Finally, climate change likely played a role; as forests shrank, hominid ancestors had to walk across grasslands to reach food sources. Those that could walk or run faster were more likely to survive predator attacks.

Idea 3.

A Medieval Story.

3.66 Million Years Ago
Hominin

In the verdant landscapes of Laetoli, Tanzania, beneath a layer of volcanic ash from a nearby eruption, a remarkable story is preserved. Dating back 3.66 million years, a series of footprints capture a fleeting moment in time when early hominins walked across the wet ash. These footprints, attributed to Australopithecus afarensis, represent one of the earliest known evidences of bipedal locomotion, a pivotal adaptation in human evolution. The prints reveal not just the mechanics of early human walking but also a snapshot of life in a world teeming with both challenges and opportunities. As these hominins moved through their environment, their upright strides marked a significant departure from their four-legged forebears, setting the stage for a journey that would eventually lead to us. The discovery of these footprints in 1976 by Mary Leakey and her team opened a window into our ancestral past, highlighting a critical step in our long, adaptive stride through history.
