The data comes from scientists who gather data in their labs, such as DNA sequences. It is meant for a number of purposes. First, if science is to repeatable, these data can be checked against other data to see if the conclusions of a paper are valid. They are also used to reduce redundancy in data collection (sequences already exist for a particular species at a particular location, then perhaps further sequencing efforts might be better spent on another species or location). Finally, they can be used as raw data in asking new research questions.
