Traditional morphology-based taxonomy, is only one way to describe "life's diversity" and species hypotheses developed based on morphology alone should be tested using different approaches with a variety of data sets [ 8].
The cost-effectiveness of such a tool to improve embryo selection can only be evaluated in prospective randomized studies that compare embryo selection based on morphology alone to an approach combining morphology and FF G-CSF quantification.
The genus Campydora was historically classified within the Dorylaimia based on morphology [ 15, 36, 38]; only Siddiqi [ 19] was the only author to suggest a relationship with the Enoplia based on the structure of the pharynx and amphids.
Classification only based on morphology may be problematic, and a true classification should be determined using the internal genes of the whole genome, coupled with the complex environmental factors.
M-phase cells were identified solely based on morphology.
In 1996 Kevin Thiele and Pauline Ladiges published a cladistic analysis of Banksia based on morphology, in which this taxon stood out as the only member of B. integrifolia to be both morphologically and geographically distinct from other infraspecific taxa.
However, the comparison of the initial identification based on morphology and the results obtained by ETS analyses were in agreement only in a few cases (data not shown).
For instance the studies based on morphology [18], [30] have considered the two taxa as single terminals while only two Tetranchyroderma species were involved in the molecular study of Todaro et al. [11].
