Question

Tasmanian wolf is a marsupial while wolf is a placental mammal. This show
A. Convergent evolution
B. Divergent evolution
C. parallelism
D. Inheritance of acquired characters.

Answer 1

Hint:It is the contrasting of divergent evolution, in which connected species evolve into different traits. On a molecule level, this can occur because of random mutation unassociated to adaptive modifications; long branch attraction.

Complete answer:
To answer this question, first, we have to know about evolution. The evolution theory suggested that a variety of animals, plants and many other living organisms on Earth have their origin in other earlier existing kinds and that the distinctive differences are because of changes in successive generations. The phenomenon of evolution is one of the basic keystones of current biological phenomena.
Now, let us find the solution from the option.
>Convergent evolution refers to the formation of similar traits by unrelated groups of organisms.
>Divergent evolution is the phenomenon of the generation of distinguishable forms from a mutual progenitor structure, for example forelimbs in the human beings, horse and bat.
>Parallelism is defined as the independent formation of the same traits by associated groups of organisms.
>Inheritance of obtained characters is Lamarckism. It states that the traits acquired due to changes in the environment, new needs, functioning and non-functioning of organs are transferred on to the future generation.

Thus, the correct option is A. i.e. Mitosis.

Note:There are several circumstances that can result in convergent evolution. Usually, convergence happens when organisms need to adjust to the same environmental habitat, like in the evolution of wide water-storing leaves and spines on cacti and Euphorbia species, that are adjusted to toleration of high drought but are local to different continents.
