Found 26 resources for the concept: Natural selection and genetic drift act on the variation that exists in a population
 | Evolution and Antibiotic Resistance
Students learn why evolution is at the heart of a world health threat by investigating the increasing problem of antibiotic resistance in such menacing diseases as tuberculosis.

 | Evo in the news: Fighting the evolution of malaria in Cambodia
This news brief from December 2009 focuses on one of the world’s most deadly infectious diseases: malaria. Malaria is normally treatable, but now some strains are evolving resistance to our most effective drug. Find out how researchers and doctors are trying to control the evolution of the disease.

 | Evo in the news: Warming to evolution
Global warming increasingly affects many aspects of our environment, from the sea level to tropical storm strength. But that's far from the full story. This news brief from July 2006 describes how global warming has already begun to affect the evolution of several species on Earth.

 | Evo in the news: Quick evolution leads to quiet crickets
The tropical island of Kauai has always been a quiet place, but now it may be getting even more quiet. This news brief, from December 2006, reveals how Kauai's cricket population has evolved into a "chirpless" variety in just a few years.

 | Evo in the news: Cheating cheetahs prosper
Biologists have discovered that female cheetahs consistently seek out multiple mates. This news brief, from July 2007, explains how the evolutionary implications of this behavior may help conservation efforts targeting these endangered animals.

 | Evo in the news: Evolution down under
This news brief, from September of 2008, describes an unusual contagious cancer currently decimating Tasmanian devil populations. Learn about the fascinating interplay between the evolution of the devils and the evolution of the disease.

 | Evo in the news: Genetic variation helps rescue endangered panthers
In the 1990s, scientists predicted that the Florida panther would be extinct within 20 years and, in 1995, formulated a bold plan to save them. This news brief of December 2010 reports on the success of that plan which gave the panther a second lease on life by the infusion of genetic variation.

 | A Step in Speciation
Students compare different subspecies of a California salamander on a grid map of California to focus on patterns of their distribution, their likely evolutionary relationships, and probable sequence of formation from the ancestral salamander.

 | Angling for evolutionary answers: The work of David O. Conover
Human activity has certainly affected our physical environment - but it is also changing the course of evolution. This research profile follows scientist David O. Conover as he investigates the impact of our fishing practices on fish evolution and discovers what happened to the big ones that got away.

 | The genes that lie beneath: The work of Leslea Hlusko
Evolutionary biologist Leslea Hlusko’s research takes her from the deserts of Ethiopia, where she hunts for hominid and primate fossils, to a baboon colony in San Antonio where she takes thousands of measurements of the primates' imposing canines. This research profile describes how the two projects are linked by a hunt for genetic variation, a key component of natural selection.

 | Biological warfare and the coevolutionary arms race
The rough-skinned newt looks harmless enough but is, in fact, packed full of one of the most potent neurotoxins known to man. Find out how an evolutionary arms race has pushed these mild-mannered critters to the extremes of toxicity and how evolutionary biologists have unraveled their fascinating story.

 | A look at linguistic evolution
We typically think of evolution occurring within populations of organisms. But in fact, evolutionary concepts can be applied even beyond the biological world. Any system that has variation, differential reproduction, and some form of inheritance will evolve if given enough time. Find out how an understanding of evolution can illuminate the field of linguistics.

 | Evolution connection: Transcription and translation
This short slide set relates the role of RNA in the processes of transcription and translation to RNA’s evolutionary history and the remnants of the RNA world. Save the slide set to your computer to view the explanation and notes that go along with each slide.

 | Evolution connection: DNA replication
This short slide set explains the fidelity of DNA replication in evolutionary terms. Save the slide set to your computer to view the explanation and notes that go along with each slide.

 | Mouse fur color
This case study in the form of a set of PowerPoint slides examines the evolution of light fur in beach mice from the molecular level up to the population genetics level.

 | The Making of the Fittest: The Birth and Death of Genes
This 13-minute film describes how scientists have pieced together the evolutionary history of the Antarctic icefish by studying its genome – an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.
