It's easy to distinguish species of sexual organisms, but how do we distinguish species of asexual organisms?
Quite often it isn't.Archosaur said:It's easy to distinguish species of sexual organisms,

Asexual speciation is a process by which new species of organisms are formed without the involvement of sexual reproduction. This means that the offspring are genetically identical to the parent organism.
Asexual speciation differs from sexual speciation in that it does not involve the mixing of genetic material from two different individuals. In sexual speciation, genetic diversity is increased through the combination of genetic material from two parents.
There are a few different mechanisms that can lead to asexual speciation, including fragmentation, apomixis, and polyploidy. Fragmentation occurs when a single organism breaks into multiple pieces, each of which can develop into a new individual. Apomixis is a form of asexual reproduction in which the offspring are produced from unfertilized eggs. Polyploidy occurs when an organism has more than two sets of chromosomes, which can lead to reproductive isolation and the formation of a new species.
Asexual speciation can be identified and distinguished through a combination of genetic and morphological analyses. Genetic studies can reveal differences in the DNA sequences of asexual organisms, while morphological studies can identify physical differences in their appearance. Additionally, asexual organisms may also occupy different ecological niches, which can further distinguish them from other species.
The potential benefits of asexual speciation include the rapid production of new species, as well as the ability to adapt quickly to changing environments. However, asexual organisms may also be more susceptible to extinction due to their lack of genetic diversity, and they may have a limited ability to evolve in response to new challenges. Additionally, asexual speciation can lead to the loss of genetic variability, which is important for the long-term survival of a species.
