Charles Darwin is best known for his work as a naturalist, developing a theory of evolution to explain biological change.
Carl Woese Lived — Carl Woese was obsessed with truth.
He wanted to discover if all life on Earth had evolved from a single common ancestor. In addition to answering his own question, he redrew the tree of life. Scientists believed there were only two fundamental types of organism: Woese discovered there was a third form — the Archaea.
Most biologists did not take his claim seriously. Some ridiculed him, most distanced themselves from him. After over a decade of controversy and frustration, his discovery became mainstream science. Before his groundbreaking work, scientists believed all species Woese classed as archaea were actually bacteria.
Unlike larger creatures such as fish or dinosaurs, scientists had never been able to confidently describe the evolutionary history of microbes.
Achievements and Key Points Biologists believed there were two fundamental domains of life: Ribosomal RNA is found in all organisms. It is a simpler molecule than DNA. Woese believed rRNA was probably one of the most ancient nucleic acids. Woese studied the genes of a large number of organisms. InWoese published work showing that methane-producing microbes are not bacteria, but belong to an entirely new, third domain of life.
Woese called this third domain the Archaea pronounced ar-KEY-ameaning ancient. Woese drew a new tree of life, emphasizing fundamental evolutionary divisions between the three domains: Bacteria, Archaea, and Eucarya. The Tree of Life The tree of life, featuring three fundamental paths taken by evolution.
One path led to bacteria. The others to archaea and eukarya. Archaea have no nucleus and under the microscope look superficially like bacteria. But in terms of the evolutionary history written in their genes, Woese discovered that archaea are as different from bacteria as they are from eukarya including you and me.
His father, Carl F. Woese, was a consulting engineer. His mother, Gertrude Nadler, was a homemaker. Carl had a younger sister, Donna. From childhood, Carl decided he wanted to be a scientist.
His mind sought truth. Science seemed to offer the best route to truth — certainly more so than people, who he found were often untrustworthy.
Carl grew up during the depression and World War 2. He attended a public high school, then went to a military school for a year. His final two years of high school were at Deerfield Academy, a prestigious private school in Massachusetts.
He was an introverted student with an unorthodox sense of humor. After graduating from high school, Woese went to Amherst College, Massachusetts.
Although at the time he had no scientific interest in biology, an Amherst professor advised Woese that the new, emerging field of biophysics might offer more exciting research possibilities than straight physics.
Woese took the advice.Read an Excerpt.
