Abstract

Sequence similarity between human and bacterial genes can be the result of several evolutionary processes, including horizontal gene transfer. Since sequence similarity searches alone fail to distinguish between the possibilities, phylogenetic analyses are needed.

Keywords:

  • horizontal gene transfer;
  • evolution;
  • phylogeny;
  • BLAST;
  • gene loss;
  • sequence similarity
