Metagenomics is defined as the application modern genomic techniques to the study of microbial organisms in natural environment, bypassing the need for isolation and lab cultivation of individual species. Metagenomics enables the genomic study of uncultured microorganisms. It is used to investigate microbial communities by deep sequencing a marker gene of choice. The date generated by metagenomic experiments both enormous and controversial result in fragmented DNA representing 10,000 different species. Areas of science have benefited more from the expansion of sequencing capability than the study of microbial communities. Adaptation of populations in the laboratory can serve as a model to test our ability to make such inferences about evolution and ecology sequencing. Using metagenomics, you can find plenty of specific genes among metagenomes and see how species evolve, looking at related genes and DNA.
