Sentence examples for evolutionary changes over time from inspiring English sources
HIV-1 mutates and recombines at extremely high rates, and the rapid generation of genetic diversity makes it possible to study the dynamics of evolutionary changes over time and to trace patterns of viral dispersal in HIV-1 epidemics [4], [5].
What they do not do, however, is cover what is known about the major evolutionary changes over time or above the species or population level (macroevolution), and how these changes are understood (Padian, 2008).
A major line of future research should be to expand the availability of fossil and other historical data that would facilitate the empirical measurement of the distribution of evolutionary changes over time for known traits and phylogenetic trees.
The functions of proteins are often more conserved in their tertiary structure than in their primary amino acid sequence, as residues that are not crucial for the function of the protein will be subject to evolutionary changes over time.
Since the sequence encoded by the glnA1 locus is the major GS of M. tuberculosis, it is expected to undergo little evolutionary change over time.
Because living things have undergone evolutionary changes over geologic time, particular kinds of organisms are characteristic of particular parts of the geologic record.
As strong selection will be required to see evolutionary changes over short time scales, theory suggests that large-effect loci (Yeaman and Whitlock 2011) or perhaps clusters of adaptive loci may be more likely to underlie a rapid response to selection.
Rather, they dispute the occurrence of major evolutionary changes over long periods of time, which by definition cannot be directly observed, only inferred from microevolutionary processes and the traces of macroevolutionary ones.
In this sense, the challenge of reconstructing the history of domestication is similar to that of studying natural evolutionary change over deep time.
This is wrong on logical grounds gorillas and chimpanzees have evolved over as long a time period as humans have—but is intuitively attractive because it seems obvious that the magnitude of human evolutionary change over this time has been substantially greater.
