A ring is simply a circular band, usually of fine metal, often with diamonds, rubies or other precious stones attached to it. The word “ring” itself denotes jewelry worn on the hand; when worn as such an accessory elsewhere, the word is also specified within the word, e.g., rings, finger rings, ring fingers and various other body rings. Various materials may be used to manufacture rings: gold, silver, stainless steel, titanium, copper and sometimes wood. Although the material is important to the appearance and value of the ring, so is the design and style. There are many types and styles of rings available for purchase:
Ranging from very simple and understated designs to very elaborate and ostentatious designs, a ring can be designed and produced in almost any way desired by the purchaser. One of the most popular of ring species is interbreed rings. Interbreeding occurs when two or more species of animals are bred together to produce a new generation of offspring that are likely to be as attractive and desirable as their parents.
With interbreed rings, one can speak of both the breeders and the offspring. Breeding takes place when two closely related species, such as dogs and cats or humans and chimpanzees, mate with a female and produce fertile children who grow up to be healthy, happy and sturdy adults. These new generation members often have substantial traits common to both parents, including strong bonding, similar lifestyles and similar characteristics. In the case of interbreeds, the new generation is often made more attractive through careful selection of favorable genes to accentuate the desirable traits of each parent and avoid unfavorable traits common to both parents.
Some research has shown that interbreeding does have an impact on speciation. Speciation is the process of identifying distinct genetic differences between organisms. Differentiation is caused by random genetic mutations that randomly occur within the DNA sequence without any chance of regulating themselves. For instance, within a human species, humans and chimpanzees have quite different genetic sequences despite similarities in their appearance. Because humans and chimpanzees differ so much genetically, there is great potential for speciation to occur and new species to form.
One reason why speciation has been studied with ring species is because ring species tend to share a lot of physical characteristics with one another. As mentioned above, speciation can occur when new genetic forms are created through the independent actions of parents. Research has also revealed a lot of genetic differences among populations, particularly in cattle, horses, deer and even rats. This results in gaps in the genetic makeup of the host species, especially in areas where a speck of gene flow from a widely divergent species occurs. These gaps can prevent the evolution of new ring species and prevent them from developing into fully functioning reproductive populations.
Similarly, an encumbrances effect is present in the evolution of most birds. The presence of a large encumbrane in the head band can restrict migration, breed and lifespan. The Ensatina greenish warbler, for example, is protected from moult by its intense colors. But a large encumbrane around its eye may prevent the species from evolving into different varieties of the Ensatina through gene flow.
