Well-preserved material of mosses and liverworts appears in the Paleogene and Neogene periods (65.5 million to 2.6 million years ago), and most of the main evolutionary lines are represented.
In the hornworts and mosses, the structure of the sporophyte, especially the sporangium, is important in distinguishing the main evolutionary lines, while gametophytic features provide the details for distinguishing genera and species.
The phylogenetic position of Microraptor, however, suggests that it diverged from the main evolutionary line leading to birds and flight, so the animal's four-winged condition is an unusual, independently evolved state.
Sexual selection is one of the main evolutionary forces that drive signal evolution.
The main evolutionary features of the evaporite tectonic on the Berati belt were conditioned from the regional tectonic phenomena.
In addition, local search is embedded in the CBGA after the main evolutionary search process to enhance the exploitation ability by further improving the elite solution.
For such complex systems, conceptual models can be used as evaluation tools in a preliminary step to identify the main evolutionary processes responsible for soil and water salinization.
The main evolutionary mechanisms leading to increases in genome complexity (i.e. gene duplication and transposon proliferation) can all potentially produce increases in DNA clustering.
Thus the greater availability of toxicity data has contributed to the evolution of QSAR models; however, because of the time consuming nature of generating extra experimental data, this factor did not represented the main evolutionary driving force.
Nothing no part of my trilobites seemed to show any prolonged, slow, steady gradual change the main pattern of evolutionary change that tradition dictated would be the main evolutionary signal I would detect with all this sampling.
While this representation is interesting to understand the effectiveness of JSD as a genetic divergence measure, it also confirms the findings of [11] regarding the main evolutionary scenario for CN.
