Eukaryota derived from this shared common ancestor much later in time than bacteria and archaea did. The longer the line of the nodes from the ancestor line the longer the time has been. Eukaryota has the longest line.Explanation:
Phylogenetic tree represents a hypothesis about evolutionary relationships
Explanation:
Phylogenetic tree is a diagram that represents evolutionary relationships among organisms.Its a hypothesis not a true facts. In a phylogenetic tree two species are related when they evolved from a common ancestor. Modern system of classification is based on evolutionary relationships. Each branch represents a divergence events. Each branch point lies a most recent common ancestor group descended from that branch point
