Have you ever heard of the “gene pool”? It’s not actually a pool filled with denim trousers but something much more interesting! Gene pools are simply the collection of all the genes that make a species. Gene pools don’t always stay the same; they are constantly shifting and changing as brand new genes come into the gene pool and others move out and are lost forever. In fact, this is the definition of evolution: changes in the gene pool that happen over time. The Untamed Science evolution portal is a gateway for learning about various topics on evolution. How does evolution work? Evolution is simply the change in the gene pool of a population over time. Mutation Mutation is very important in evolution because it’s the only way that completely new genes ever happen. Most mutations don’t have any effect on the organism, or they may even have a negative effect. Migration When organisms move in and out of an area, they also take their genes with them!
