Wisconsin`s White Deer: Separating Science and Myth by MaLenna

... The term "piebald," as used for most animals, refers to a "pinto-like" color. In Wisconsin game regulations, however, piebald is defined as "...a deer that has some brown hair, even if only a small patch, on any part of the body that is not part of the head, hooves, or tarsal glands..." (DNR Bureau ...

Long-time observers of white deer all make the same comment: The white deer are in no way recognized as different or ostracized by their brown herdmates. White and brown deer not only live together just fine, the white deer often do ...

Microevolution

Microevolution is the change in allele frequencies that occur over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow, and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed 'macroevolution' which is where greater differences in the population occur.Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution. Ecological genetics concerns itself with observing microevolution in the wild. Typically, observable instances of evolution are examples of microevolution; for example, bacterial strains that have antibiotic resistance.Microevolution over time leads to speciation or the appearance of novel structure, sometimes classified as macroevolution. Macro and microevolution describe fundamentally identical processes on different scales.
