You can finish reading "Newly Discovered 'Orphan Genes' Defy Evolution, here.An important category of "rogue" genetic data that utterly defies evolutionary predictions is the common occurrence of taxonomically restricted genes, otherwise known as "orphan genes." These are now being discovered in the sequencing of all genomes.Many multicellular animals share similar sets of genes that produce proteins that perform related biochemical functions. This is a common feature of purposefully engineered systems. In addition to these standard genes, all organisms thus far tested also have unique sets of genes specific to that type of creature.The authors of a recent review paper, published in Trends in Genetics, on the subject of orphan genes stated, "Comparative genome analyses indicate that every taxonomic group so far studied contains 10–20% of genes that lack recognizable homologs [similar counterparts] in other species."
