Researchers have discovered evidence suggesting that human blood cells may have evolved from single-celled organisms that existed around 700 million years ago. By reconstructing the evolutionary history of blood and immune cells, scientists uncovered surprising links between modern human biology and some of Earth’s earliest life forms.
The study reveals how primitive cellular functions gradually evolved into the complex immune systems seen in humans today. Researchers say the findings could reshape understanding of how blood cells developed over evolutionary time and provide new insights into immunity, inflammation, and disease.
The discovery highlights how deeply modern human biology remains connected to ancient forms of life that existed long before animals appeared on Earth.
