From very primitive beginnings, with a very crude tool kit of stones, we now have a very advanced tool kit, and our tool use has really reached unprecedented levels: we've got buggies to Mars; we've mapped the human genome; and recently even created synthetic life, thanks to Craig Venter.
Od vrlo primitivnih početaka, s vrlo grubim alatima od kamena, sada posjedujemo vrlo napredne alate, a korištenje tih alata je zbilja doseglo rekordnu razinu. Imamo bagije na Marsu, mapirali smo ljudski genom, a nedavno smo čak stvorili sintetički život, zahvaljujući Craigu Venteru.
