Q.23  Give an example for convergent evolution and identify the features towards which they are converging.

When unrelated animals converging to the same form or structure, that isvery adaptive in their common environment. lt is called convergent evolution, e.g., Austrailian marsupials and placental mammals. 

Such as (placental wolf and Tasmanian wolf). These two sub-classes of mammals have adapted in simi;ar ways to a particular food supply, locomotor skill or climate.

Their resemblances in iverall shape , locomotor mode and  feeding and foraging are superimposed upon different modes of reproduction, the feature that accurately reflects their distinct evolutionary relationships.
