Sentences with phrase «taxonomic level»
"taxonomic level" refers to the position or category a living thing is classified into in a scientific system called taxonomy. It helps scientists categorize and organize different organisms based on their characteristics and similarities. The taxonomic levels start from broad categories like kingdom or domain, then become more specific, including phylum, class, order, family, genus, and species. Full definition

This reveals a greater ecological diversity in an early mammaliaform clade at a more fundamental taxonomic level not only between major clades as previously thought.
Genera are the next taxonomic level up from species and are easier to detect in fossils.
Moreover, these studies illustrate how more complex Hox - regulated traits diverge at higher taxonomic levels.
Transitional fossils can occur between groups of any taxonomic level, such as between species, between orders, etc..
Even if one accepts «kinds» at the taxonomic level of families, too many forms to fit on the Ark and again, requires hyper - evolution to account for presently observable biodiversity (i.e. the genera, species derived from the highly limited genetic diversity of the founding «kinds» pairs).
Similarly, there is no known intrinsic biological limit to the ability of adaptive microevolutionary change to continually and indefinitely modify, over sufficient lengths of time, the gross morphology of any particular form, i.e. observable macroevolutionary change up through the higher taxonomic levels.
Lastly, note that once isolated, microevolutionary changes continually acc - umulate providing ever greater morphological divergence which over time allows for segregation of the many various forms within the higher taxonomic levels.
At the taxonomic levels L2 (phylum) and L6 (genus), statistically significant differences were demonstrated in bacterial profiles, particularly in T2DM group.
