  1. Archaeopteryx

Show answer

Organic evolution is the events involved in the evolutionary development of a species. It means that all life descended from other life, although features may have changed dramatically along the way. Organic evolution involves modifications to existing species, not the development of new ones. Darwin's finch is an example, which all evolved from a common species. Gradually these 13 species got modified and adapted to their particular niche and feeding habit within Galapagos island.

So, the correct option is 'Darwin's finches'.
