The 3rd Domain is the untold tale of ways the invention of a brand new type of lifestyles -- first ridiculed, then overlooked for the previous thirty years via mainstream scientists -- is revolutionizing technological know-how, undefined, or even our look for extraterrestrial life.
Classification is a major factor for technological know-how: when you do not know what you are looking at, how are you going to interpret what you notice? beginning with Carolus Linnaeus within the seventeenth century, scientists have lengthy struggled to reserve and categorize the various varieties of lifestyles in the world. yet through the early twentieth century the tree of lifestyles looked as if it would have stabilized, with major domain names of lifestyles at its roots: single-celled and multi-celled organisms. All creatures healthy into the sort of groups.
Or so we notion. yet in 1977, a lone scientist named Carl Woese decided that archaea -- biochemically and genetically certain organisms that reside and thrive in probably the most inhospitable environments on the earth -- have been a different kind of existence, in contrast to whatever visible in the world ahead of. This stunning discovery used to be solely incompatible with the long-standing class of lifestyles as we all know it. yet because it became out, archaea weren't lifestyles as we all know it, and the tree of existence needed to be uprooted as soon as again.
Now, archaea are being hailed as the most very important medical revelations of the 20 th century. The 3rd Domain tells the tale in their unusual strength and investigates their fantastic background to supply a riveting account of an impressive discovery.
