Adaptive Radiation - A Brief concept with Examples

 

• Adaptive radiation is the evolutionary process by which many species originate from a common ancestor  in an area and radiate  to form other different species.

• The phenomenon of adaptive radiation was first observed by Darwin when he visited Galapagos Island.

• Adaptive radiation  has developed great morphological and ecological diversity.

• The main reason behind adaptive radiation is the adaptation of organisms to new ecological niches.

• The  examples  of adaptive radiation are  Darwin's finches  on the Galapagos island, Marsupial animals  in Australia and Placental mammals.

• The concept of Adaptive Radiation was given by Charles Darwin in the year 1835 when he visited on the Islands Galapagos. This concept brought big change in the history of science.

• It is a procedure by which an common ancestor produces several species and This entire process of Adaptive Radiation takes place in a group of phenotypically dissimilar animals but related species. It is mostly marked during the extinction of species or physical disturbance.

• In simple words, It is a kind of evolutionary process   that leads to the creation of several new kinds of species that are born from a single species of a parent.

• Adaptive radiation is  a procedure where living organisms  are diversified too quickly from their ancestral stock and increase in the number of species.

• The adaptive radiation is the result of natural selection, mutation, genetic drift, or migration. It indicates evolutionary variations that are quite adaptive to a specific environment.

• Adaptive radiations  create diversification throughout the biological species.

• This concept of the evolution of species emerges when environmental forces drive evolutionary divergence and create different species which are capable of making interact with the environment.

• Adaptive radiation evolution is regarded as a relatively quick development of several species from a single common ancestor.

• This concept has seen to take place when any living organism arrives at a new location and different types of behaviors start to impact its chances of survival.

• One of the most common examples of an adaptive radiation evolution is the growth of mammals..

• Adaptive radiation is a correlation of phenotype-environment: This is an important link between the environment and the physiological and morphological traits of species that exploit it.

• The third adaptive radiations is an important feature of this kind of evolution is trait utility: It shows the performance of traits in conforming environments.
