Homologous Structure
Homologous Structures are those structures, that have the same anatomical structure. But they perform different functions. Homologous Structures are generally a missing link among a set of species. It proves that those species were closely linked up with each other at any point in time. Due to the evolution process, they developed two distinct species. But their origin is the same. Due to some factors, the Homologous Structures developed with the help of natural selection. from the outside of the structure, they can resemble two different structures. As they perform two different functions. But if those structures can be noticed internally, there will be a clear similarity among them. This type of structure developed from a certain evolutionary process, known as Divergent Evolution.
What are Homologous Structures?
Evolution is a continuous process of nature. Any species need to upgrade itself. Thus it can able to survive in a continuously changing environment. This change always occurred in a positive direction. This means after the changing of a creature, they became more developed than the previous version. Evolution works in such a way. It takes millions & millions of years to complete a process. Some scientists believe that Evolution is a never-ending process. It g-oes running for an infinite time. During this process, a creature will be always developed. There are many structures developed during the evolution process of certain species. Homologous Structure is one of them.
