What Is Analogous Structure?
Analogous Structure is the opposite of Homologous Structure. Homologous Structure is associated with Divergent Evolution. But Analogous Structure is associated with Convergent Evolution. If two structures of two different species are engaged for functioning in the same type of work, then those structures are known as Analogous Structures. Also, these structures never derived from the same ancestor of two different species. These structures need to be developed in each of the species by the natural selection process. Nature will force the species to develop such structures in their body. This type of same structure can develop in some species due to the same habitat.
Analogous Structures have many examples, like the wings of the bird & the butterfly. Both the wings help them to fly in the sky. But their Anatomical Structures are different. The same goes for the other animal also. Like the tail of a fish & tail of tadpoles serves the same function. It helps to swim in the water. But their Anatomical Structure is different. These structures are known as Analogous Structures.
Convergent Evolution
Evolution is a developing process. It is a continuous & immortal process by which new species take place in nature. Evolution is a process where from an existing creature a new completely different creature evolved. In every living thing, evolution can be observed. Though evolution takes millions of times to create a new species, but still in the present time also, evolution is the key force that maintains nature. Scientists believe that there are many types of evolution present. Among them, Divergent Evolution is the major one. But others also are responsible for creating new species. Among others, Convergent Evolution is next to the Divergent Evolution.
Types of Evolution
There are four types of the evolutionary process is present. They are:
- Divergent Evolution
- Convergent Evolution
- Parallel Evolution
- Co-Evolution
