An example of speciation is the Galápagos finch. Different species of these birds live on different islands in the Galápagos archipelago, located in the Pacific Ocean off South America. The finches are isolated from one another by the ocean. Over millions of years, each species of finch developed a unique beak that is especiall… See more
Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its o… See more
There are five types of speciation: allopatric, peripatric, parapatric, and sympatric and artificial. See more
In parapatric speciation (3), a species is spread out over a large geographic area. Although it is possible for a… See more
Allopatric speciation (1) occurs when a species separates into two separate groups which are isolated from one another. A physical barrier, such as a mountain range or a waterway, makes it impossible for them to bree… See more
Sympatric speciation (4) is controversial. Some scientists dont believe it exists. Sympatric speciation occurs when there are no physical barriers preventing any members of a species fro… See more

- Darwin’s Finches
A major example of allopatric speciation occurred in the Galapagos finches that Charles Darwin studied. There are about 15 different species of finches on the Galapagos islands, and they each look different and have specialized beaks for eating different types of foods, such as insects, see… - Grand Canyon Squirrels
When the Grand Canyon was formed, it created a natural barrier between the squirrels living in the area. About 10,000 years ago, the squirrel population was separated from each other by this geographic change and could no longer live in the same area. Over thousands of years, the divi…

True examples of sympatric speciation have rarely been observed in nature. Sympatric speciation is thought to occur more often in bacteria, because bacteria can exchange genes with other individuals that aren’t parent and offspring in a process known as horizontal gene transfer. Symp… - In Cichlids
Another example of sympatric speciation is found in two species of Midas cichlid fish (Amphilophusspecies), which live in Lake Apoyo, a volcanic crater lake in Nicaragua. Researchers analyzed the DNA, appearance, and ecology of these two closely related species. The two speci…
