Abstract
What if cancer cells are more than just rogue mutations—what if they represent a startling evolutionary throwback to our single-celled ancestors? In this paper, we uncover striking parallels between embryonic stem cells (ESCs) and cancer cells, focusing on their shared reliance on glycolysis (the Warburg effect), absence or minimal expression of lamin A, and capacity for indefinite self-renewal. We further reveal how these features mirror primordial life forms that predate Earth’s oxygenation. By exploring the evolutionary sequence—mitosis first, followed by sophisticated DNA repair and apoptosis—we illuminate how metabolic insufficiency in mitochondria can stall the apoptosis program, unleashing unregulated proliferation reminiscent of ancient single-celled behaviors. Building on Thomas Seyfried’s metabolic theory of cancer, we posit that restoring robust mitochondrial function might reverse cancer cells’ atavistic shift or even trigger their long-delayed cell death. From the subtle epigenetic changes that accompany mitotic chromosome segregation to the universal vulnerability of DNA under conditions of compromised energy, our synthesis bridges molecular biology, evolutionary theory, and clinical oncology. Readers will discover compelling evidence that cancer may be, at its core, a metabolic disease—one that seizes upon ancestral cellular states to circumvent modern-day apoptotic defenses. This perspective not only reframes our understanding of cancer’s origins but also promises novel therapeutic avenues targeting mitochondrial metabolism, inspiring us to look backward in order to move medicine forward.
