Protosterol Biota
Recently, scientists have discovered a “lost world” of ancient organisms in rocks billions of years old from northern Australia.
- Scientists say that this discovery could change the world’s current understanding of the earliest ancestors of humans.
- These microbes, known as the Protosterol Biota, are part of a family of organisms called eukaryotes and lived in Earth’s water world about 1.6 billion years ago. Eukaryotes have a complex cell structure that includes mitochondria, the “powerhouse” of the cell, and a nucleus. Modern forms of eukaryotes include fungi, plants, animals, as well as unicellular organisms such as amoeba.
- Humans and all other nucleotide animals can trace their ancestry to the last eukaryotic common ancestor (LECA), which lived more than 1.2 billion years ago. Eukaryotes can be single-celled or multicellular.
