Do archaea undergo the same horizontal gene transfer processes as bacteria?

  The exchange of genetic material is a major driving force for genome
  evolution across the tree of life and has a role in archaeal
  speciation, adaptation and maintenance of diversity.

  Horizontal gene transfer (HGT) is the sharing of genetic material between organisms that are not in a parent-offspring relationship. HGT
  is a widely recognized mechanism for adaptation in bacteria and
  archaea.

  Potential hotspots of horizontal gene transfer between archaea and
  bacteria include hot springs, marine sediments, and oil wells.
