Found 23 resources for the concept: There is a fit between organisms and their environments, though not always a perfect fit
Adaptation: The case of penguins
The process of natural selection produces stunning adaptations. Learn about the history of this concept, while you explore the incredible adaptations that penguins have evolved, allowing them to survive and reproduce in a climate that reaches -60°C!

Interview: Geerat Vermeij on the Fossil record
This interview with MacArthur Fellow and paleobiologist, Geerat Vermeij, covers much ground, including adaptations in the mollusks he studies, evolutionary arms races, punctuated equilibrium, extinctions, macroevolution, and the value of diversity.

Lines of evidence: The science of evolution
The theory of evolution is broadly accepted by scientists — and for good reason! Learn about the diverse and numerous lines of evidence that support the theory of evolution.

Comic strip: Survival of the sneakiest
This comic follows the efforts of a male cricket as he tries to attract a mate, and in the process, debunks common myths about what it means to be evolutionarily "fit."

Evo in the news: A fish of a different color
This news brief, from February 2006, describes how a mutated zebrafish gene may help us understand human evolution and the genes underlying human skin color. Humans and zebrafish both inherited the same pigmentation gene from their common ancestor.

Evo in the news: Conserving the kakapo
This news brief, from April 2006, chronicles how researchers are using evolutionary theory to guide their strategies for conserving a critically endangered parrot - with some impressive results!

Evo in the news: Musseling in on evolution
This news brief, from September 2006, reviews a recent case of evolution in action. In just 15 years, mussels have evolved in response to an invasive crab species. Find out how biologists uncovered this example of evolution on double time.

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: Got lactase?
The ability to digest milk is a recent evolutionary innovation that has spread through some human populations. This news brief from April 2007 describes how evolution has allowed different human populations to take advantage of the nutritional possibilities of dairying and links evolution with the prevalence of lactose tolerance among people of different ethnicities.

Evo in the news: Sex, speciation, and fishy physics
More than 500 species of cichlid fish inhabit Africa's Lake Victoria. This news brief from March 2009 explains new research suggesting that the physics of light may have played an important role in cichlid diversification and in the recent drop in their diversity.

Evo in the news: Evolving altitude aptitude
This news brief from October 2010 examines new research that makes it clear that Tibetan highlanders have not just acclimated to their mountain home; evolutionary adaptations have equipped them with unique physiological mechanisms for dealing with low oxygen levels.

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.

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.

Sexo, especiación y física subacuática
Evolución en las noticias relata una reciente historia que señala como comprender física básica puede revelar como la evolución esta ocurriendo hoy — en especial, como la física de la luz tiene influencia sobre la selección sexual, especiación y el colapso de la biodiversidad, producto de la polución causada por los humanos...

Mejores biocombustibles gracias a la evolución
Actualmente, la mayoría de nosotros llenamos nuestro tanque de gasolina con combustibles fósiles, es decir, restos de plantas y animales que murieron muchos millones de años atrás y eventualmente se convirtieron en petróleo — pero, por supuesto, esto no puede perdurar para siempre. El petróleo es un recurso limitado y en algún momento se va a terminar. Para ayudar a solucionar este problema, muchos científicos, políticos, gente de negocios y ciudadanos preocupados han puesto sus esperanzas en los biocombustibles...
