One bottleneck is that describing the shape of a neuron requires quantitatively specifying many morphological features, examples of which are the length and branching patterns of neurites, and their spatial distribution.
These phenotypes may currently be coevolving because Mexipyrgus exhibits striking examples of morphological differentiation in shell morphology and pigmentation among habitats [[ 10- 12]; Fig. 2].
Since then, even more spectacular examples of morphological covariation have been found in the tube and tongue lengths of long-tongued flies and the flowers that they visit (Anderson and Johnson 2008, 2009; Pauw et al. 2009).
Baudrimont uses a semi-phonetic system with the following diverging conventions: Examples of morphological features in Erromintxela: Most verbs have a Romani root plus the Basque verb forming suffix -tu.
Other examples of morphological support for initially surprising molecular results are summarized in Online Supporting Information (Table S2).
There are a growing number of examples of morphological divergence between subspecies in which researchers have been unable to detect divergence in a variety of selectively neutral loci [13].
While there are numerous paleontological examples of morphological innovations enabling a major ecological transition [e.g.], [ 13], [14,15], their value is limited to inferences based only on preserved, hard structures.
However, these examples of morphological and ecological convergence do not support the Metaves/Coronaves division.
In plants, the giant lobelias from the Hawaiian Islands and tropical Africa have been cited as remarkable examples of morphological convergence in the family Campanulaceae (the bellflower family).
In fact, the striking morphological similarity of some Upper Triassic Triops sp. fossils from Germany and extant T. cancriformis [ 29] makes this notostracan one of the best examples of morphological stasis and 'living fossils' [ 30].
have to date not been the subject of a detailed phylogenetic study, it is unclear if these taxonomic changes reflect the evolutionary relationships within this portion of the genus or are examples of morphological convergence [ 10].
