While Dolly is often the answer given to this question, there were actually earlier (less exciting) clonings.
In 1952 a tadpole was said to have been cloned, but there is disagreement about whether it was a true clone or not.
Chinese embryologist Tong Dizhou successfully inserted the DNA from a male Asian carp into the egg of a female Asian carp to create the first fish clone in 1963.
In 1973 Tong inserted Asian carp DNA into a European crucian carp to create the first interspecies clone.

* Tadpole: (1952) Many scientists questioned whether cloning had actually occurred and unpublished experiments by other labs were not able to reproduce the reported results.
* Carp: (1963) In China, embryologist Tong Dizhou cloned a fish. He published the findings in an obscure Chinese science journal which was never translated into English.
* Sheep: (1996) From early embryonic cells by Steen Willadsen. Megan and Morag cloned from differentiated embryonic cells in June 1995 and Dolly the sheep in 1997.
* Rhesus Monkey: Tetra (female, January 2000) from embryo splitting
* Cattle: Alpha and Beta (males, 2001) and (2005) Brazil.
* Cat: CopyCat "CC" (female, late 2001), Little Nicky, 2004, was the first cat cloned for commercial reasons.
* Mule: Idaho Gem, a john mule born 2003-05-04, was the first horse-family clone.
* Horse: Prometea, a Haflinger female born 2003-05-28, was the first horse clone.
