Evolution is extremely important to the long-term survival of any species. Conditions in any habitat are constantly shifting and it's up to the plants and animals in those environments to adapt or face extinction. Genetic diversity is how nature solves this problem, and as each species in a habitat slowly branches out, the ones that are most well-suited to survive will always be the ones that carry on their genetic material and this, over time, is what evolution is all about. However, humans have thrown a pretty serious wrench in nature's plans, isolating certain species for the purposes of farming, and new research suggests that this practice may ultimately doom them.
A new study in Proceedings of the Royal Society B focuses on the population diversity of Atlantic salmon. The fish has a long history of being farmed, but fish farming in places like Sweden may ultimately hinder the ability of the fish to evolve and adapt to a changing climate. The researchers examined the genetic diversity of caught salmon from the 1920s with salmon caught today, and the findings are troubling.
