In embryology, animals with bilateral symmetry, like arthropods (and also humans) produce three germ layers. Animals with radial symmetry like echinoderms produce two.
Note that the term 'anthropod' should not be confused with 'arthropod' - anthropod is not a phylum nor taxon but is a broader term meaning human or humanoid.
