Question

What species concept from the following would classify 2 different lizards as the same species and why?

- Phylogenetic S.C

-Morhpholiocal S.C

-Biological S.C

Answer 1

Phylogenetic species concept-

• Group of individuals from a common ancestor.

Morphological species concept-

• Based on morphological features
• According to it species,is a population or a group of populations morphologically different from other populations.
• species are distinguished from each other on the basis of observed similarities and differences.

Biological species concept-

• groups of interbreeding natural populations reproductively isolated from other such groups.
• According to it species are absolutely realities,typifies by individuals and a not mere man -made abstractions.
• a biological species forms a reproductive community and ecological unit and its genetic unit.
• it takes into account the morphological and anatomical physiological, cytological, biochemical, genetical, ecological ethological features of organisms.

From this most accepted one is biological species concept.

Since the concept include all the morphological,anato anatomical,physiological, cytological, biochemical ,genetical ecological &ethological features..So with this we can classify the 2 lizards into same species.
