  — Cathleen O'Grady, Ars Technica, 3 Nov. 2017
• The new study suggests the DNA disparity, not uncommon in small island populations, is a clear case of genetic drift: Chance determined which genes got passed to subsequent generations.
  — Bridget Alex, Discover Magazine, 1 Jan. 2019
• If the reproductive material could be readily frozen and defrosted, those studies would be easier to conduct and replicate, since researchers wouldn’t have to work around spawning schedules or struggle against genetic drift.
  — Jacob Brogan, Smithsonian, 13 July 2017
• The magnitude of genetic drift as a frequency is inversely proportional to population size.
  — Razib Khan, Discover Magazine, 13 Sep. 2012

  — Zach Zorich, Discover Magazine, 25 Feb. 2016

  — Aidin Vaziri, San Francisco Chronicle, 9 July 2022
• Now, a team of researchers is using the analogy of evolution to explain language change, arguing that key factors in biological evolution—like natural selection and genetic drift—have parallels in how languages change over time.
  — Michael Erard, Science | AAAS, 1 Nov. 2017

  — WIRED, 28 Nov. 2022

  — Jennifer Ouellette, Ars Technica, 9 Feb. 2023
• Small, isolated groups of Oriental domestics gradually acquired distinctive coat colors and other mutations through a process known as genetic drift, in which traits that are neither beneficial nor maladaptive become fixed in a population.
  — Andrew C. Kitchener, Scientific American, 1 Sep. 2015
• In a growing population, chance effects, known more formally in evolutionary theory as genetic drift, can become more powerful than natural selection.
  — Quanta Magazine, 2 Aug. 2013

  — Washington Post, 3 Nov. 2019
• In the more extreme cases this produces recessive diseases (and because inbreeding reduces effective population and increases the power of random genetic drift deleterious recessives can even fix within a population rather quickly).
  — Razib Khan, Discover Magazine, 18 July 2013
• Recall that random genetic drift changes allele frequencies due to conventional sampling processes, with greater variation generation to generation across small populations.
