Question

Why is morphological species concept especially useful in paleontology? What is the difference between biolgical species concept and morphological?

Answer 1

• PALEONTOLOGY; IT IS THE STUDY OF HISTORY OF LIFE ON EARTH FOCUSED ON FOSSILS
• MORPHOLOGICAL SPECIES CONCEPT ; A SPECIES IS CHARECTORISED BASED ON IT'S SIZE,SHAPE,STRUCTURAL YFEATURES

SINCE CHARECTORISATION OF MORPHOLOGICAL FEATURES ARE EASY TO APPLY IN STUDY OF HISTORY OF LIFE ESPECIALLY BASED ON FOSSILS MORHOLOGICAL SPECIES CONCEPT IS USEFUL IN PALEONTOLOGY

OTHER REASONS ;

• APPLICABLE TO BOTH SEXUALLY AND ASEXUALLY REPRODUCING INDIVIDUALS
• APPLICABLE TO FOSSIL STUDIES

DIFFERENCE BETWEEN MORPHOLOGICAL AND BIOLOGICAL SPECIES CONCEPT

MORPHOLOGICAL SPECIES CONCEPT	BIOLOGICAL SPECIES CONCEPT
DEFINITION; DEFINED AS A GROUP OF POPULATION,THEY HAVE THE POTENTIAL TO INTERBREED IN NATURE AND TO PRODUCE VIABLE FERTILE OFFSPRING	DEFINITION;  CHARECTORISES A SPECIES IN TERMS OF SIZE,SHAPE, STRUCTURAL FEATURES
GENE FLOW BETWEEN POPULATION KEEPS POPULATION AS ONE SPECIES	MEASURES PHENOTYPIC FEATURES OF ORGANISMS
INCLUDES PRE ZYGOTIC AND POST ZYGOTIC BARRIERS	PHENOTYPE MAY REFLECT ENVIRONMENT NOT GENE FLOW
REPRODUCTIVE ISOLATION IS DIFFICULT TO DETRMINE	MORPHOLOGY CAN BE EASILY OBSERVED APPLICABLE TO BOTH SEXUALLY AND ASEXUALLY REPRODUCING SPECIES APPLICABLE TO FOSSIL STUDY
LIMITATIONS NOT APPLICABLE TO ANALYSE FOSSIL SPECIES NOT APPLICABLE TO SPECIES REPRODUCE ASEXUALLY NOT APPLICABLE TO SPECIES THAT HYBRIDISE FREELY	LIMITATION ; NOT APPLICABLE TO HYBRIDISATION INTERMEDIATE PHENOTYPES
