The evolution of aquatic habits in pinniped carnivorans presents an ideal case study of the effect of ecological transitions on evolutionary processes because both terrestrial and aquatic groups are well represented in modern faunas.
We focused on the correlated evolution of interstitial habits and vertebra number, because, despite being among the smallest gobies, Luciogobius species have vertebra numbers (i. e., 35 50) that far exceed those typically found in other Gobiidae (i. e., 26) [ 12].
Also in accordance with ecological adaptation as a drive to diversification is the marked morphological diversity of megabats, such as the high variance in body size, as compared to the other bat families [ 68] and the independent evolution of nectarivorous habits and associated morphological adaptations in several of the pteropodid clades.
Solvent effects are principally accounted for by an interfacial modification of surface energies and the evolution of crystal habit under cycles of growth or dissolution can be predicted also.
The evolution of leaf habit and leaf shape in Hydrocharitaceae provides several cases of evolutionary adaptation to diverse habitats.
Since these groups occur mostly at high elevations in the Himalayas (Incarvillea) and the high Andes of South America (Argylia, Tourrettia) [ 40], it seems likely that evolution of herbaceous habit has evolved independently in these two regions in response to the common environment.
A molecular phylogeny based on extensive taxon sampling is required to establish systematic relationships within Corvus so that questions pertaining to historical biogeography, brain size and the evolution of innovative foraging habits and tool use might be addressed.
Examples include evolution of terrestrial larval habits by damselflies in the Hawaiian, New Caledonian, and Pohnpeian faunas [11], [12], raptorial carnivory in Hawaiian caterpillars [13], and colonization of land by Caribbean truncatellid snails [14] and Jamaican sesarmid crabs [15].
On the basis of the resultant phylogenetic frameworks, the evolution of their feeding habits was traced using data from analyses of stomach contents, habitat depths, and observations of oral jaw tooth morphology.
Beyond the significant correlation between increasing intestinal length and decreasing animal prey in diet, interpretation of the evolution of specific dietary habits in the Terapontidae must be treated with caution as we currently have limited insights into the physiological processes associated with extracting and utilizing nutrients from consumed foods.
