Question

You are interested in trying to work out whether adaptive radiation in mollusks occurred after the Cretaceous extinction, What sort of data would you need to collect?

You would need to work out the total number of species present in different locations at the present time.

You would need to examine the number of species present before the extinction event with the number present after the extinction event.

You would need to determine the number of species present before the extinction event and the number present today

You would need to work out the number of species present immediately after the extinction only.

Answer 1

You would also need to gather information on the different ecological niches occupied by mollusks before and after the extinction event, as well as any morphological changes that may have occurred in the surviving species. Additionally, studying the genetic relationships and evolutionary history of various mollusk species would help determine whether adaptive radiation occurred.
