The Federation of American Societies for Experimental Biology

Evolution Education Matters

Evolution is one of the most thoroughly studied and supported concepts in science

Evolution is the foundation of biology

Evolution is the only scientific explanation for the diversity of life

Evolution is critical for understanding and advancing medicine

What is Science?“Science is a particular way of knowing about the world

In science, explanations are restricted to those that can beinferred from confirmable data--the results obtained throughobservations and experiments that can be substantiated byother scientists

Anything that can be observed or measured is amenable toscientific investigation

Explanations that cannot be based on empirical evidence are not

a part of science

-Teaching About Evolution and the Nature of Science

The National Academy of Sciences (1998)

What is Evolution? Process by which the diversity of life on

earth developed over time from common ancestors

Over time, the genetic makeup of a population changes, resulting in changes in the distribution of characteristics in that population

These changes result in differences within

species (microevolution) as well as the emergence of new species (microevolution)

Charles Darwin

Evolution is Science! Evolution is one of the most thoroughly studied

concepts in the biological sciences

Evolution is based on volumes of scientific evidence obtained through experimentation and observation of the natural world

Evolutionary principles have been rigorously tested using the scientific method

Evolution is accepted by the scientific community as the only scientific account for the diversity of species

Evolution is a Critical Topic in Science Education

Evolution is the Foundation of Biology

Evolution is a unifying concept in the life sciences

It connects and provides a framework forunderstanding the various disciplines in biology, frombotany to genetics to physiology and beyond

Evolution is the Foundation of Biology

Evolution accounts for the diversity of life…Evolutionary mechanisms, including genetic mutation, migration of species, genetic drift, and natural selection, give rise to variation within species as well as to the rich array of distinct species.

The Beak of the Finch: Natural Selection In Action

In the Galapagos Islands, finches evolved a variety of beak types adapted forcracking open different kinds of seeds.

Changes in weather patterns have been shown to change the kinds of seedsavailable—for example during drought, tough seeds that are difficult to crackare more abundant than soft seeds.

Finches with large beaks adapted for eating these hard seeds are more likelyto survive and reproduce than other finches.

These finches become more abundant compared to those withsmall beaks.

Systematic change in organisms over time…The fossil record shows the emergence and disappearance of species over time as well as “intermediary” or “transitional” forms between species.

Intermediary Forms are Evidence for Evolution

And the similarities among living thingsThe process of evolution has produced an astounding diversity of species! Yet organisms from yeast to worms to humans have striking similarities as a result of having descended from common ancestors.

Similarities Among Species Indicate Common Descent

The Building Blocks of Life All life is made of essentially the same basic materials. All species are remarkably alike at the cellular, molecular, and genetic levels, and all use DNA as the basic mechanism of heredity.

Biological development The developmental stages through which a diverse array of organisms pass and the genes that control these stages are similar.

Structural AnatomyCommon ancestry has resulted in remarkable similarities or homologies in the skeletal structures of animals as different as frogs, birds, and humans.

Evolution is Still Happening!

Insects evolve resistance to pesticides

New strains of influenza emerge

Disease-causing microbes develop resistance to antibiotics

Living things, including plants, birds, insects, and mammals adapt to climate change

Understanding Evolution, Advancing Medicine

Human Immunodeficiency Virus (HIV) Evolutionary biology has played an important role in explaining the origin and transmission of HIV, the variation in virus types, and the development of appropriate treatments.

Avian Influenza Developing computer models of the evolution of avian flu and other viruses may allow scientists to predict how quickly they may spread, aiding the development of preparedness plans.

Genetic Markers of Disease Researchers are using the principles of evolution to examine genetic mutations that may account for increased risk of acquiring certain diseases. These has led to the discovery of genetic markers for Alzheimer’s and coronary artery disease.

Evolution is Not Controversial Among

Scientists

There are No Scientific “Alternatives” to Evolution

Creationism and other non-scientific beliefs:

Do not rely on natural explanations of phenomena

Are not based on observation or experimentation

Do not generate testable predictions

Are not accepted by the scientific community as explanations for the diversity of life

Support Evolution Education

Support the inclusion of evolution in science curriculaand education standards

Oppose teaching non-scientific alternatives to evolution,including intelligent design and other forms ofcreationism

Oppose “teach the controversy,” “critical analysis,” and other proposals that weaken evolution education

Support Evolution Education
