Biology

  • February 22 – In Roslin, Scotland, scientists announce that an adult sheep named Dolly has been successfully cloned and was born in July 1996.[1]
  • March 4 – United States President Bill Clinton bars federal funding for any research on human cloning.
  • March 14 – The widely cited 1973 John/Joan study of gender reassignment of a twin boy who lost his penis to a botched circumcision is exposed as fraudulent. The supposedly successful outcome for "Joan" reported by John Money had been cited as proof that gender was determined by nurture, yet the patient (later revealed as David Reimer was in fact deeply unhappy and had returned to his original gender by the age of 15, thus indicating the exact opposite thesis.[2]
  • April 25 – Scientists announce that human artificial chromosomes have been created.
  • July 10 – In London, scientists report their DNA analysis findings from a Neandertal skeleton which support the out of Africa theory of human evolution placing an "African Eve" at 100,000 to 200,000 years ago.
  • November 6 – The discovery of klotho, a gene involved in human aging, is reported.[3][4]
  • November 19 – In Des Moines, Iowa, Bobbi McCaughey gives birth to septuplets in the second known case where all seven babies are born alive, and the first in which all survive infancy.
