Metagenomics is a field of research which uses genomic data from a large number of organisms in an ecosystem to attempt to characterise the ecosystem holistically. This technique has only recently been possible with the advent of high throughput sequencing. Metagenomics is particularly good for investigating life which can’t be readily grown/cultured in a lab – which is a surprisingly large amount of the microbial world. One particular part of the microbial world, our own bodies, is being investigated in the Human Microbiome Project.
