In Australia, marsupials and placental mammals have evolved to share many similar characteristics. This type of evolution may be referred to as :
- Adaptive Radiation
- Divergent Evolution
- Cyclical Evolution
- Convergent Evolution
The Correct Option is D
Solution and Explanation
When more than one adaptive radiation appeared to have performed in an isolated geographical area that is representing different habitats, is known as convergent evolution.

Concepts Used:
Mechanisms of Evolution
The mechanism of evolution has been explained with theories such as the Big Bang Theory, the Theory of Darwin, and the Hardy-Weinberg Equilibrium where evolution is the process of natural selection that causes changes in the traits of species over multiple generations.
The Big Bang Theory:
The most widely accepted theory for the origin of life on Earth and its various forms is the Big Bang Theory. According to the hypothesis, as a result of a massive explosion, the universe was created 20 billion years ago.
Hardy-Weinberg Equilibrium:
According to the idea of Hardy-Weinberg, allelic frequency and gene pool remain stable throughout generations. Furthermore, the allelic frequencies add up to 1.
Theory of Darwin:
The Theory of Darwin's natural selection hypothesis provided a more reasonable explanation for the emergence of new species. As a result of adaptation to changing environmental conditions, natural selection led to the evolution of multiple species from a single species.
