Answer:
The position of Hemichordata, in the scheme of classification of animals, has been controversial. In 1814, Sedgwick and Huxley suggested the affinities of Enteropneusta (Hemichordata) with the vertebrates and it was in 1885 Bateson considered this group as a subphylum of the phylum Chordata. Metschinkoff (1865) stated that Enteropneusta had certain affinities with Echinodermata. Spengel (1893) showed the relationship of Enteropneusta with Annelida.
