From the tiniest protocells to modern humans, our species has undergone a remarkable journey of adaptation, innovation, and survival.
In this article, we take a look at the key developmental stages in the evolution ofย life on Earthย that led to the emergence ofย Homo sapiensโus!
1. Protocells and Early Microorganisms
The first life forms on Earth were simple, single-celledย microorganismsย known as protocells. These precursor cells lacked a nucleus or other membrane-bound organelles, and they had simple genetic proteins called RNA.
Over time, RNA complexified into the more stableย DNA. Protocells slowly developed specialized organelles, becoming more complex microbes that would eventually form eukaryotes โ the complex, unicellular organisms that would birth a diverse array of life forms, from simple sponges to complex animals.
