Answer:
An individual can be placed or classified into a particular species depending on the concept a scientist has considered,
The three most prominent are Biological, morphological and phylogenetic species concept.
1. Biological species concept- Individuals that can interbreed naturally are placed into the same species. Therefore, Biological species concept, not applicable for extinct species
2. Morphological
- Relies on similarities in structure
This species concept places individuals having similar body structures into the same species. It can be easily applied to asexual and extinct species.
3. Phylogenetic
- Based on evolutionary history
Species are classified according to a common ancestor.
4. Morphological and Phylogenetic
Accommodates asexual reproduction
Species acceptance criteria can be subjective
5. Morphological, Phylogenetic, and Biological
Used by scientists in classification
All the three concepts are used for classification.
