Found 13 resources for the concept: There are similarities and differences among fossils and living organisms
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.

Xenosmilus
Students play the roles of paleontologists on a dig. They “unearth” a few fossils at a time and attempt to reconstruct the animal the fossils represent.

Understanding Macroevolution Through Evograms
Evograms convey information about how a group of organisms and their particular features evolved. This article explains how to read evograms and delves into the evolutionary history of whales, tetrapods, mammals, birds, and humans.

Great Fossil Find
Students are taken on an imaginary fossil hunt and hypothesize as to the identity of the creature they discover. Students revise their hypotheses as new evidence is "found."

A Strange Fish Indeed: The “Discovery” of a Living Fossil
Through a series of fictionalized diary entries, this case recounts the 1939 discovery by Marjorie Courtenay-Latimer (and identification by J.L.B. Smith) of a living coelacanth, a fish believed to have been extinct for 70 million years.

Evo in the news: One small fossil, one giant step for polar bear evolution
This news brief from April 2010 describes what scientists have learned by extracting DNA from a polar bear fossil more than 100,000 years old. Though the fossil itself was just a fragment of the skeleton—the lower left portion of the jaw, still containing a tooth—the DNA had a lot to say about polar bear evolution.

Evo in the news: More than morphology
This news brief, from August 2006, describes recent research on T. rex, with a special focus on how paleontologists move beyond the shape of the animal's bones to learn about aspects of its life that don't fossilize very well: its physiology, sensory abilities, and population dynamics.

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.

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.

Darwin's "extreme" imperfection?
Darwin used the words "extreme imperfection" to describe the gappy nature of the fossil record - but is this really such a problem? This article delves into the topic of transitional fossils and explores what we have learned about them since Darwin's time.
This article appears at SpringerLink.

Webcast: Fossils, genes, and embryos
In lecture three of a four part series, evolutionary biologist David Kingsley examines the original objections to Darwin's theory and shows how modern evidence supports the theory.
This lecture is available from Howard Hughes' BioInteractive website.
