Answer:
To study the evolutionary relationships of the earliest forms of life on Earth we need to examine a structure that is present in all cells and changes very slowly over time.
All life on Earth was initially divided into three main Domains: the Bacteria, the Archaea, and the Eukarya, based on the similarities of their:
Ribosomal RNA
Explanation:
Ribosomal ribonucleic acid: RNA (rRNA, mRNA, and transfer RNA (tRNA), is a noncoding molecule of RNA in cells, which is the main building block for ribosomes protein-synthesizing organelle, exported to the cytoplasm to help translate the information in messenger RNA (mRNA) into protein. They are essential to all living organisms.
Because all these cells are similar in nature within the bacteria, the archaea and the eukaryait, there is a thought that all cells came from a common universal ancestor cell that eventually evolved into three different kind of cells, representing each of these domains.
