Abstract
The article presents a study which shows that halophilic archaea can reproduce asexually that enable homologous recombination between distinct species. The researchers reveal that archaea can exchange DNA through lateral gene transfer (LGT) that break down species barrier in geographic isolation and genetic incompatibility. The study indicates that halophilic archaea can form interspecies cell fusions between the two chromosomes before the cells separate to form haploids.
