Match the correct set. Column I I. Fossil II. Devonian period III. Cambrian period IV. Ordovician period Column II A. 345-405 million years ago B. Fossillium C. 425-500 million years ago D. 500-600 million years ago
The correct matching of the periods and descriptions is as follows: Fossil corresponds to Fossillium, Devonian period is from 345-405 million years ago, Cambrian period is from 500-600 million years ago, and Ordovician period is from 425-500 million years ago. Hence, the correct set is I – B, II – A, III – D, IV – C.

Which is not applicable to the Biological species concept ?
