It is an indispensable condition for the construction and maintenance of ecosystems,as well as for a constant adaptability to evolutionary changes.
Governments prefer to deal with evolutionary changes and not with revolutionary ones.
In fact, the evolutionary changes in the DNA of certain viruses and growing resistance of pathogens against antibiotics and conventional medications make it even more important to learn how to improve immune system.
The mechanism of occurrence of the devices is responsibleall the same basis- evolutionary changes with fixing and passing by inheritance necessary in specific conditions of the characteristics.
When men and women fall victims to excessive anxiety, they are simply reverting to the natural estate of their far-distant ancestors; and when anxiety becomes actually painful,it inhibits activity and unfailingly institutes evolutionary changes and biologic adaptations.
Each of these evolutionary changes, individually and together, point to a new path for us to ensure the well-being of the planet and its people.
In the 1970s Stephen Jay Gould and Niles Eldredge proposed the theory of punctuated equilibrium which holds that stasisis the most prominent feature of the fossil record, and that most evolutionary changes occur rapidly over relatively short periods of time.
As the turning point approaches, the realization that evolutionary changes of this magnitude cannot be prevented by short-term political activities provides our strongest hope for the future.
Kimura's theory was simple and elegant, but the classification of mutations into the distinct classes- beneficial, neutral, or harmful- seemed too simple to me. My own work showed that borderline mutations, thosewith very small positive or negative effects, could be very important in driving evolutionary changes.
Their research developed a phylogenetic tree that determined the evolutionary changes that were required for a particular protein to change into another protein based on the underlying amino acid sequences.
The Commission ' s deliberations are taking place at a time of increasing and sustained foreign direct investment(FDI) flows to and from both developed and developing countries(section I). Furthermore,important deep-rooted evolutionary changes are occurring in FDI patterns and activities of transnational corporations(TNCs), leading to the emergence of a new FDI landscape.
Beneficial ones would spread until the entire species carried them. Evolutionary changes, including morphological ones, were thought to be the result of the accumulation and distribution of beneficial mutations, and the genetic makeup of populations was believed to be close to homogeneous, with only a few rare, random mutations creating differences between one individual and another.
For example, in the traditional“tree of life” representation of evolution, the branches always move apart, never merging,implying that species' ancestry follows a linear path, and that all evolutionary changes along this path occur within the lineage being traced. But examination of genomes- particularly microbes- has shown that genes moving between distantly related organisms are an important catalyst of evolutionary change. .
Mosaic evolution(or modular evolution) is the concept that evolutionary change takes place in some body parts or systems without simultaneous changes in other parts.
It has been reported that some bindingsites have potential to undergo fast evolutionary change.
As I have seen in this series, the extinction of the dinosaurs wasn't theonly time that a catastrophe kick-started a major evolutionary change.
The transition from indexical to symbolic communication is therefore a key evolutionary change because it may signal the origin of language[9][10][11] and symbolic thought.[ 12][ 11][ 13][ 14].
Lastly, with reference to the Secretary-General ' s report on the reform of the Department for General Assembly and Conference Management,he noted that the Department had undergone an evolutionary change. However, the successful implementation of the integrated global management system was dependent on the provision of adequate resources.
The conditions required for rapid evolutionary change to occur in human populations exist. But, given that measurable alterations in a trait over time can occur for many reasons- including those related to shared culture or environment- or randomly(“genetic drift”), studies demonstrating this phenomenon are rare.
During the late Oligocene and early Miocene periods,camels apparently underwent swift evolutionary change, resulting in several genera with different anatomical structures, ranging from those with short limbs, those with gazelle-like bodies, and giraffe-like camels with long legs and long necks.
But recent evidence suggests that large changes, caused by the absorption of a chunk of alien genetic material, may be just as significant. Indeed, the absorption of entire organisms- such as the two bacteria that formed the first eukaryotic cell(the more complex cell type found in multicellular animals)-can generate large and crucial evolutionary change.
The Episodic Nature of Evolutionary Change".

That process of organic evolutionary change has been most welcome.
Teilhard de Chardin Orthogenesis and the Mechanism of Evolutionary Change".

Until this discovery,we thought we had a pretty good idea about the patterns of evolutionary change.
That process of organic evolutionary change should continue. So too, for the moment, should consideration of those issues in the Open-ended Working Group.
Thirdly, there is agreement that the process of organic, evolutionary change in the Council ' s working methods, which has enhanced its transparency, should continue.
