Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck We report the construction of a large-insert metagenomic library in fosmids in an Escherichia coli host. Here, we have reviewed the evolution of Microbiology into Metagenomics to describe exhaustively a microbial community in terms of taxonomic diversity and metabolic potential. Metagenomics is a molecular technique that enables the characterisation of thousands of genes from different individual organisms within a sample (Prosser 2015;Semenov 2021). It is named by analogy with the rapidly expanding, quasi-random shot grouping of a shotgun.. This technology Metagenomics, defined as the culture-independent genomic analysis of microbial communities, has emerged as a powerful new field of research in microbiology over the last two decades. Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth.Simply, it is also defined as the study of the history of life forms on Earth. The broad field may also be referred to as environmental genomics, ecogenomics, community genomics or microbiomics.. We are an Open Access publisher and international conference Organizer. Association of the gut microbiota with various diseases has been reported, though the specific components of the microbiota that affect the host response leading to disease Veterinary Microbiology is concerned with bacterial and viral diseases of domesticated vertebrate animals (livestock, companion animals, fur-bearing animals, game, poultry, but excluding fish) that supply food, other useful products or companionship. The old saying, "do what you can with what you've got" certainly is inspiring. CMAERA is a tool to aid people using metagenomics to study microbial community ecology.
