Since the late Holocene, anthropogenic changes to alluvial stratigraphy and channel morphology have often been greater than those left by climate change.
Thus, apparent similarities in marine tetrapod skull and tooth morphology have often been interpreted to reflect convergent adaptation towards specific diets and feeding modes.
Given this putative plasticity, it seems likely that similar (e.g., level of reduction of a given bony element) or identical character states (e.g. independent loss of a bone or parts of it) in adult morphology have often been interpreted as synapomorphies or autapomorphies when they are actually homoplasies.
In 30 dpi males, the distal testis located in the anterior has often reached its adult morphology.
In examining cranial variability in Erinaceus concolor [15], the types and magnitudes of the differences in the nasomaxillary suture and cranial morphology pointed to the existence of morphotypes and not different species, as has often been observed in other groups.
U. radiata has often been mistaken for U. inflata because of their similar morphology and overlapping distribution.
It has often been called a "self-evident" mechanism because it necessarily follows from three simple facts: Variation exists within populations of organisms with respect to morphology, physiology, and behaviour (phenotypic variation).
Unfortunately, for many sexually dimorphic features, only the morphology has been documented in detail and it is often unclear how they are being used.
Hence, morphology has become less significant in taxonomic and floristic studies, but detailed morphological (including ultrastructural) investigations can often help to interpret molecular results such as unusual phylogenetic positions of some organisms.
Lobular in situ or invasive breast cancer is often multifocal or bilateral at presentation, and even if unilateral this morphology has a tendency to predispose to cancer in the contralateral breast [ 3, 13].
