These stunning results were gathered from proteomic experiments - experiments designed to look at the entire set of proteins being expressed - from 50 different tissue samples. From looking at the expressed proteins, researchers were able to better estimate how many protein coding genes exist in the human genome. Scientists then compared the human coding region genome to other animals. As reported in an article titled Human Genome Found to have Fewer Genes Again by Margaret Lutze, no proteins were identified that differentiated humans from primates. Additionally, co-author of the study David Juan stated "the number of new genes that separate humans from mice [those genes that have evolved since the split from primates] may even be fewer than ten."
