Vast genetic changes can occur in hatchery-raised fish in as little as one generation, according to the latest study from Oregon State University. This poses a significant threat to wild populations that come in contact with their genetically unique relatives.
A new study revealed face mites – microscopic animals that live on our faces and in our hair – evolved along side humans. Moreover, people from different parts of the world host different mite lineages that follow families through generations.
Mice rely on scent to recognize relatives they have never even met before. This is important when choosing the right nesting partners and to ensure that the right genes are passed on to offspring.
