Sentence examples for morphological evolutionary trends from inspiring English sources

Both ammonoid lineages display empirical morphological evolutionary trends of some shell characters.

However, such morphological evolutionary trends among ammonoids have been rarely discussed and quantified in detail [ 38, 39, 47, 55- 58].

Among the documented parallel morphological evolutionary trends, some can be explained as covarying traits, meaning that some morphological trends can result from constructional constraints [ 39, 162- 165].

The repeated and similar large-scale morphological evolutionary trends of distinct lineages suggest that adaptation by means of natural selection (functional constraints) is the major cause of parallel evolution, a very common phenomenon in extinct and extant lineages.

Third, we inferred phylogenetic relationships and major morphological evolutionary trends within the section Calochroi by integrating molecular phylogenetic analyses of single and combined DNA sequence datasets with morphological, chemical and ecological features.

We inferred intra- and interspecific phylogenetic relationships as well as major morphological evolutionary trends within section Calochroi based on 576 ITS sequences, 230 ITS + 5.8S + D1/D2 sequences, and a combined dataset of ITS + 5.8S + D1/D2 and RPB1 sequences of a representative subsampling of 58 species.

Furthermore, this morphological evolutionary trend occurred during the most intense phase of the "Devonian nekton revolution" [ 79].

Nevertheless, morphological (phenotypic) evolutionary trends do occur in independent lineages and can display striking parallel changes (for a Recent mollusc example, see [ 17]).

The recognition of homology is the first step to reconstruct the morphological relationships and evolutionary trends in any plant group.

Using a wide variety of examples, he demonstrates how changes in the timing or rate of developmental events can influence evolutionary trends in morphological features and life history traits.

While these structures are quite diverse in form, they fall into a limited number of morphological types and seem to show some evolutionary trends.
