Theoretical and experimental studies reveal challenges ahead in achieving a true systems-level understanding of this process and its outcomes. Across a very broad taxonomic range animals frequently respond differentially to close kin even if those kin were previously unfamiliar. Logically this differentiation between individuals according to kinship requires well-defined mechanisms to allow recognition. And whereas animals may learn the cues of familiar individual kin during rearing recognition of unfamiliar kin must really be recognition of genetic similarity - either to self or to other known kin. A challenge in this area lies in discovering the cues that animals use for genetic recognition of kin and the genetic encoding of such cues. In many vertebrates odors are key to the recognition process and have been widely implicated as cues that allow genetic kin recognition in many species of fish reptiles and mammals Figure 1 . However vertebrate scents are generally complex and there have been few attempts to identify the specific scent components used in kin recognition or their genetic basis.
