Discovery of DNA. Today, we know that DNA is the genetic material: the molecule that bears genes, is passed from parents to children, and provides instructions for the growth and functioning of living organisms. But scientists didnât always know this.

Zircon is a zirconium silicate mineral. It is the principle source of the element zirconium (Zr) 1  usually small and inclusion-rich.  Zircon is highly resistant to weathering (maybe the most resistant of any mineral) This, and its high specific gravity, favor its concentration in placer deposits and alluvial gem gravels.
