In this brief survey, we describe about the number of genes of metazoans in order to estimate loughly how many genes are required for generating intelligent artificial neural network using genetic algorithms. The numbers of genes are about 10,000 to 20,000 from C.elegans to whales each, and the number of human genes that relate to nervous tissue formation is estimated to be about 3,500 to 8,500.
