Question

The purple sea star, Pisaster ochraceus, lives in rocky intertidal and subtidal habitats along the U.S. west coast. Originally it was thought to be a distinct species from a similar orange sea star that lived in the same habitat, until genetic analyses confirmed that the two are simply different color morphs of the same species. What species concept was used originally? Morphological species Biological species Geneological species Phylogenetic species

Answer 1

Answer: Option A is correct
Explanation:
Morphological species = Organisms that are identical in their morphology belong to the same species
It is given that the purple sea star and orange sea star were initially identified as two distinct species due to their external morphological appearance. i.e. Based on their morphology, they were classified as two different species.
