Utah science standards also call for students to cite evidence for changes in populations over time using concepts of evolution as an explanation.
While historians of demography have long studied patterns of fertility to explain changes in populations over time, historians of medicine and sexuality have only more recently begun to pay attention to early modern ideas and concerns about fertility and barrenness.
Evolution is the change in populations over time that has lead to the diversity of life on earth (Mayr 2001).
Evolutionary change in populations: the frequencies of phenotypes (and ultimately of the alleles responsible for these phenotypes) change in populations over time. .
Focusing on evolution as a process effecting change in populations over time, in contrast to the comparatively myopic sorting of the resulting pattern, arguably represents the most significant theoretical shift in thinking about evolution since Darwin.
The principles of phenotypic variation within populations, differential fitness, and change in populations over time were included (at either the novice or the expert level) in 75%, 72%, and 65% of students responses, respectively; largely neglected the genetic component of the evolutionary process.

2007) consists of sampling a population at regular intervals and estimating metrics (i.e., heterozygosity, relatedness, allelic richness, effective population size) via standardized analysis that permits meaningful characterization of change in populations over time.
They do not take into account changes in methods of diagnosis or shifts in population over time.
