Who coined the term ‘emergence’?

The term emergence was coined by the biologist Ernst Haeckel in the early 20th century. Haeckel was an evolutionary biologist who is most famous for coining the term "ontogeny recapitulates phylogeny." This means that during embryonic development, the embryo gradually resembles the adult organism. Haeckel's theory of recapitulation was later used by the philosopher Karl Popper to argue against the theory of evolution.
