By doing it, the slugs are effectively bypassing traditional evolution ... t resulted in any new dog species (cocker spaniels and poodles can still interbreed, for example) but merely a bunch ...

These same evolutionary changes can also result in the populations evolving into separate species. For example, adaptation to different environments might cause differences between populations in ...

Some critics of the theory of evolution argue that it doesn't ... A well-studied example of a ring species is the salamander Ensatina escholtzii of the Pacific Coast region of the United States.

A population of one species can only evolve into more than one species if groups within the population become isolated from each other. Different mutations will occur in the isolated groups ...

But this adaptation is now outdated.© Wendy Cutler via Flickr (CC BY-NC 2.0) Selection for adaptation is not the only cause of evolution. For example, species change can be caused by neutral mutations ...

That is, species are generally stable ... questions for further research. What, for example, are the processes that produce rapid evolution? Population genetic studies show us that small changes ...

Species behaviour has the potential to lead morphological evolution, by placing the organism under novel selection pressures. Many adaptations of living species could have originated in this way, ...
