We have found that the beginnings of human disturbance of these systems began well before these studies, and include changes that occurred during each cultural period -- aboriginal, European colonial, and more recent global exploitation of sea life.

... development of a mammalian kidney, from its early beginnings in the embryo to its adult role as a vital filtration system, has been described by UCSD School of Medicine researchers using DNA gene-chip technology and novel software.
