Abstract

According to a bold and imaginative theory, cells of all plants, animals and fungi are a combination of two or more totally different microbial genomes. This theory has now been extended to understand evolutionary processes in eukaryotes: that is, speciation in eukaryotes has occurred (and continues) not only by accumulation of random mutations, but also by repeated physical merging of microbial cells in some specific order, and acquisition of different microbial genomes. The genomic sequence of organisms have provided evidence of alliances, mergers and acquisition of genomes between different individual species to form new species. This theory challenges biologists to recreate a eukaryotic cell in the laboratory from forced mergers of earliest extant microbes.
