The phrase horizontal evolution is used in evolutionary biology to refer to:

  • Concerted evolution, whereby individual members of a DNA family within one species are more closely related to each other than to members of the same type of DNA family in other species;
  • Horizontal gene transfer, where genes are transferred from one organism to another by means other than genes received from an ancestor

    • It is sometimes used by creationists as a synonym for

  • Microevolution, development of genetic changes below the speciation threshold
