    "abstract": "A new suggestion for pattern formation in biological systems is proposed. The\ninteraction of two signaling pathways provides complex patterning. The\ninteraction of two pathways involves few of the biochemical complexities of the\npathways. The \u0027Wnt\u0027 pathway is proposed to be one of these, in interaction with\nothers, one at a time, perhaps sequentially, such as Hunchback (Hh), Notch,\nBMP, etc., those involved in development of metazoa. It is further shown how\nsuch interactions can easily lead to such epithelial movements as gastrulation.\nNumerical simulations of the model are given.",
