Adaptive radiation convergence and the marsupials

adaptive radiation convergence and the marsupials What's interesting about this adaptive radiation is that marsupials evolved in many of the same ways that our placental mammals have in the america's and elsewhere this similar evolution is known as convergent evolution, and i find it truly amazing that despite being in completely different locations we see many of the same morphologies.

More number of marsupials live in australia, along with few species of placentals the marsupials have survived, evolved, have undergone adaptive radiation to occupy different or diversity of habitats in australia this adaptive radiation of marsupials is called marsupial radiation.

Marsupial and placental mammals diverged from a common ancestor more than 100 million years ago, and have evolved independently ever since the two groups have different modes of reproduction, yet within each group individual species that occupy similar niches have evolved similarities in overall shape, locomotion, and feeding habits. Invaded south america and replaced many marsupial species over 200 species of marsupials live in australia, along with many fewer species of placentals the marsupials have undergone an adaptive radiation to occupy the diversity of habitats in australia, just as the placentals have radiated across north america.

This is an example of adaptive radiation causing convergence let’s say two animal populations lived in one habitat somewhere right in the centre of australia one carried its young in pouches (marsupial), the other had placental connections serving the same purpose. Placental mammals in australia also exhibit adaptive radiation in evolving into varieties of such placental mammals each of which appears to be ‘similar’ to a corresponding marsupial for example, placental wolf and tasmanian wolf. Adaptive radiation is divergence or change in phenotype according to habitat when organism leaves original niche and enter another (multiple) niche of different environments it undergoes changes to suit the new environment this is adaptive radiation convergent evolution is when different species. In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches.

Convergent evolution is similar to parallel evolution, which occurs when two independent species evolve in the same direction and thus independently acquire similar characteristics for instance, gliding frogs have evolved in parallel from multiple types of tree frog.
