How could evolution have created the human body so perfectly? This was the question that inspired my journey of exploration—a journey I assumed would lead me to reaffirm the theory of evolution. But as I measured and compared the human body to engineered products, what I discovered was completely unexpected. Analyzing systems like the cardiovascular network and structures like teeth, I began to notice striking parallels between the human body and the designs we create in engineering. The precision of symmetrical and asymmetrical elements, the focus on safety, and the completeness of the design all mirrored the principles used to build cars, machines, and other complex systems. I anticipated finding randomness and imperfection—hallmarks of natural selection. Instead, the evidence pointed in the opposite direction. Most surprising of all, I was able to calculate the odds of such intricate design arising by chance, and the results left me stunned. The probability of the human body being a product of random gene variation was vanishingly small. This revelation led me to a groundbreaking conclusion: gene variation—the mechanism credited with driving evolution—is not random at all. It appears to be a product of intentional design. In “On the Origin of Humankind”, I invite readers to join me on this intellectual journey and consider the evidence for a revolutionary perspective on our origins. If the human body bears the unmistakable hallmarks of engineering, could it be that humankind was designed? This book explores that provocative question with clarity and insight.
