With every newly sequenced species we discover hundreds of novel protein coding genes. Many of these "orphan" genes have been experimentally proven to have dramatic functions in development, sexual dimorphism, pathogen resistance, and social traits like symbiosis. Whereas in the past, researchers viewed genes as the product of continuous variation acting on ancient material, we now know that novel genes may arise de novo from non-genic sequence. Thus evolutionary experimentation is not limited to tweaking existing genes or their regulatory patterns. Any orphan genes that arose in the distant past, should appear today as lineage-specific genes (or gene families). The ...
