This is the blog for GW students taking Human Evolutionary Genetics. This site is for posting interesting tidbits on: the patterns and processes of human genetic variation;human origins and migration; molecular adaptations to environment, lifestyle and disease; ancient and forensic DNA analyses; and genealogical reconstructions.

Conservation Laws of Hybrid Species
Hybrid species are relatively rare in nature and are often perceived with some negative connotations due to the implications they are unnatural. Hybridisation, however, occurs quite frequently in nature and, especially with the current global decline of diversity, it is essential to keep these hybrids protected in order to maintain a large variety of species in nature. The article presents the increasing necessity to make defined laws protecting the species in order to keep the diversity for gene flow between species relevant, and emphasises the differing perceptions on genetic hybridisation based on the familiarity with individual species; mammals having generally negative connotations, where amphibians or reptiles are generally more neutral. The most important aspect of the protection of the species is to maintain biodiversity and allow for adaptations to occur without human interference in the species prevalence.
