Yes- archaea is another name for archaebacteria.

The End.(If I am wrong, then don't blame me- blame ditionary.com and jsyk, I am NOT trying to dis dictionary.com, because they have a definition for the Beatles, which makes me VERY EMOTIONALLY HAPPY!!! 8D So don't think that I'm trying to dis dictionary.com!

Key genetic sequences suggest that archaea are more closely related to members of domain?

Key genetic sequences suggest that archaea are more closely related to members of the domain Eukarya than to bacteria. Phylogenetic studies have revealed similarities in ribosomal RNA and other genetic markers, indicating a closer evolutionary relationship between archaea and eukaryotes. This finding has significant implications for our understanding of the tree of life and the evolution of cellular complexity.
