Frontmatter - Population Genetics and Microevolutionary Theory - Wiley Online Library

Microevolution is the change in allele frequencies that occurs over time within a population. 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.

Evolution Part 4A: Population Genetics 1

Population genetics is a field of biology that studies the genetic composition of biological populations, and the changes in genetic composition that result from the operation of various factors, including natural selection.

First published: 6 February About this book The advances made possible by the development of molecular techniques have in recent years revolutionized quantitative genetics and its relevance for population genetics.

A recent paper in this journal has challenged the idea that complex adaptive features of proteins can be explained by known molecular, genetic, and evolutionary mechanisms. It is shown here that the conclusions of this prior work are an artifact of unwarranted biological assumptions, inappropriate mathematical modeling, and faulty logic. Numerous simple pathways exist by which adaptive multi-residue functions can evolve on time scales of a million years or much less in populations of only moderate size.

I've read a few chapters and skimmed through much of the book, and my current take is that it's a bit too wordy in the exposition. I'd have preferred that there be more technical boxes and a more thorough scattering of compact formalisms. That being said, Templeton is a clear writer and the text is pretty penetrable I enjoyed the coverage of quantitative genetics especially. Also, he didn't seem to take a kitchen-sink approach, a few themes came in for thorough treatment. If you're interested in familiarizing yourself with this field I still think Principles of Population Genetics is a better bet, but then you know my biases which I stated above. It's a sad state of affairs that every such textbook needs an appendix on probability and statistics. Shouldn't we know that stuff before we pick up a textbook like this?
