Christian B. Anfinsen, Stanford Moore, and William H. Stein share a Nobel Prize in Chemistry, with Anfinsen cited for his work on ribonuclease, especially concerning the connection between the amino acid sequence and the biologically active conformation, and Moore and Stein cited for their contribution to the understanding of the connection between chemical structure and catalytic activity of the active centre of the ribonuclease molecule.
Bob Bakker publishes "Anatomical and Ecological Evidence of Endothermy in Dinosaurs" in Nature, arguing that dinosaurs were warm-blooded animals.
Harry Whittington shows a preliminary reconstruction of the Burgess Shale species Opabinia at a Palaeontological Association meeting, and the crowd roars with laughter.
In the late summer of 1973, Republican Vice President Spiro Agnew was under investigation by the United States Attorney's office in Baltimore, Maryland, on charges of extortion, tax fraud, bribery and conspiracy. In October, he was formally charged with having accepted bribes totaling more than $100,000, while holding office as Baltimore County Executive, Governor of Maryland, and as Vice President of the United States. On October 10, 1973, Agnew was allowed to plead no contest to a single charge that he had failed to report $29,500 of income received in 1967, with the condition that he resign the office of Vice President. Agnew is the only Vice President in U.S. history to resign because of criminal charges.

Half in jest, Francis Crick and Leslie Orgel suggest that ancient aliens may have seeded the early Earth with DNA, and all life on this planet arose from that.
Peter and Rosemary Grant begin a long-term study of finches on the Galápagos Islands. In succeeding years, as they watch finches adapt to alternating wet and dry conditions, the Grants will uncover evidence that evolution proceeds more rapidly than what Darwin estimated.
Taking a line from Through the Looking Glass, Leigh Van Valen establishes the "Red Queen" hypothesis of coevolution between predator and prey: "it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!"
Heinz Tobien collects a primate tooth fragment from limestone rocks in southern Germany. Studies published decades later, in 2001 and 2011, will suggest that the fossil is 17 million years old, and that a hominoid migration into Eurasia occurred 3 million years earlier than previously thought.

Donald Johanson and his team discover a female fossil hominid (to be later named Australopithecus afarensis) and call her Lucy. Lucy's discovery establishes that hominids walked upright before developing large brains, overturning some long-held beliefs about hominid evolution. Her status as a direct ancestor of modern humans, however, will remain controversial.
Heavy equipment operator Porky Hansen accidentally uncovers a mammoth tusk while leveling ground for a building. The site will reveal many more mammoths, becoming a tourist attraction for Hot Springs, South Dakota.

Mary-Claire King and Allan Wilson publish their finding that human and chimpanzee DNA sequences differ by roughly 1 percent, meaning humans have more in common with chimps than chimps do with gorillas. King and Wilson suggest that humans and chimps differ largely in the DNA that switches on and off genes.
