Final answer:
Horizontal Gene Transfer (HGT) facilitates sharing of genetic material and has an important role in the evolution and history of bacteria and archaea.
Step-by-step explanation:
Horizontal Gene Transfer (HGT) facilitates sharing of some genetic material between distantly related lineages of bacteria and archaea, and plays an important role in their evolution and history. HGT allows for the transmission of genetic material from one species to another through mechanisms other than parent to offspring, and can occur through processes such as transformation, transduction, and conjugation.
