The first animals evolved from their single-celled ancestors around 800 million years ago, but new evidence suggests that this leap to multi-celled organisms in the tree of life may not have been quite as dramatic as scientists once assumed. Researchers demonstrate that the single-celled ancestor of animals likely already had some of the mechanisms that animal cells use today to develop into different tissue types.
