Thus, if the patterns observed in Table 1 were due to convergent evolution of groups of functionally important sites in different lineages, such convergent evolution does not play an important a role in present-day evolution of measles virus.
Moreover, data on current modifications to distribution ranges due to global changes are also required to link differential Quaternary histories to present-day evolution.
Thermal evolution models suggest that the existence of a present-day magnetic field in a terrestrial planet requires a crystallizing core.
We finally discuss the role of the basement in the present-day tectonic evolution of the Carboneras Fault, and explore the northern and southern terminations of the fault and how the strain is transferred to nearby structures.
The result reveals that many of the salt structures in the region are still active and that future coastline will run with a WNW ESE trend, arguing that the compressional stresses related to the Alpine collision are the prime factor for the present-day landscape evolution.
Since it is the field of evolutionary biology that studies the processes that lead to organic diversity and that concerns itself with the study of the history of present-day organic diversity, evolution is a central theme in the study of biology.
Among present-day species, convergent evolution has led to the development of similar traits among different falconiforms.
"Indeed, the question in this case can more properly be styled as follows: When do present-day circumstances — the evolutions in the Government's surveillance capabilities, citizens' phone habits, and the relationship between the N.S.A. and telecom companies — become so thoroughly unlike those considered by the Supreme Court thirty-four yeago ago that a precedent like Smith simply doesn't apply?

The extraordinarily complex tectonic evolution of the East and Southeast Asian island arcs and marginal basins constitutes an excellent present-day analogue of the processes that may have produced the Altaid collage during the Paleozoic.
In present-day biology teaching, however, evolution is still mostly taught as only one topic among many.
