When Were Animals Created. Currently, the earliest confirmed animal discovered in the fossil record is approximately 558 million years old, but it is likely that an even earlier ancestor existed that. For decades scientists thought that complex animals—multicellular organisms with differentiated tissue types—originated in the cambrian explosion. To be sure, a riot of novel forms burst into existence during this time, including the ancestors of many of today’s major animal groups. About 575 million years ago, multicellular life forms began to proliferate. All have persisted since roughly 3.7 billion to 3.5 billion years ago during the archean eon (4 billion to 2.5 billion years ago), products of the great evolutionary process. The first recognisable animals may have evolved by this time, much earlier than was once believed. This event, called the avalon explosion, occurred as the planet left the glacial phase of the cryogenic.
