Morphospecies: A species that only differs from others in terms of morphology.

Strength ;

Differences in physical characteristics serve as the basis for defining species.

species are simpler to distinguish because they are regarded as species if several organisms share a similar appearance.

because it is a simpler approach to categorize organisms.

Weakness ;

Quite subjective, thus it might be difficult to decide which characteristics to use to identify a species.

There is no thought given to reproduction or reproductive seclusion.

Errors might arise while identifying species if morphological characteristics are not clearly visible, remain in an immature form, or are damaged.

Biological : Biology-related or having to do with life and living things. refers to a material created from a living thing or one of its byproducts in medicine. Biologicals can be used to treat, diagnose, or relieve disease symptoms.

Strength ;

species distinguished by uniqueness.

Populations make up species rather than isolated individuals.

isolated populations in terms of reproduction.

In this case, species serve as both an ecological and genetic unit. In its surroundings, the species as a whole interacts with other species. It is a genetic unit that functions as a gene pool, and each person is in possession of a fraction of that gene pool.

Species are reproductive groups where members identify potential partners for reproduction.

Weakness ;

Only applies to creatures that reproduce sexually.
species that are not distinguished by any outward features.
This concept cannot be used to evaluate hybrid complexes.

Phylogenetic :

The study of evolutionary relationships among biological things, most frequently between species, people, or genes, is known as phylogenetics (which may be referred to as taxa).

Strength ;

The smallest group of individuals within whom a parental pattern of ancestry and descent is discernible is referred to as a species in this context.
Each species needs to be distinct from every other species.
Diagnostic traits that can be used to categorize reproductive communities must be passed down from one generation to the next.
The species, or group of people, must not contain any other exclusive groups.

Weakness ;

Removing reproductive isolation as a factor in species classification.
Recognizes any character, not only morphological ones, as being appropriate for diagnosis.
Many species that are recognized by other concepts are not taken into account.

Evaluation:

According to the comparison above, adopting the morphological or morphospecies notion is the simplest method to identify a group as a species.

If conditions are favorable, all features must be clearly visible and undamaged, all organisms must be of the same age group or close to it, and the characteristics to be used as characters for differentiating must be pre-specified or pre-determined by researchers

2. The phylogenetic species idea is useful for tracing ancestry since it recognizes species as the smallest collection of people who share a common ancestor.

But given the removal of reproductive isolation or patterns, as well as the non-use of morphological traits, this is completely undesirable.

3. The biological species notion is the one that is most widely recognized. Because it recognizes the reproductive system and declares that a population, rather than a collection of unrelated or disconnected organisms, constitutes a species.

This general observation fits quite well with the statement of this concept, namely that species serve as genetic and ecological units. We can observe normally that one species interacts with another species even after being isolated (reproductively), and that the species also serve as a reservoir of genes. In light of all of the information, we can say that the idea is viable and likely to produce positive outcomes.
