A quarry site in Nevada carries the evolutionary history of a population of stickleback fish that resided there when it was a freshwater lake.
The hominid fossil record of the past six million years gives us surprising insights into the path of human evolution.
The genetic mechanisms by which evolution occurs, and an overview of the evidence for evolutionary theory.
How and why butterflies and fruit flies got their spots, and the fossil record for human evolution.
Comparing features of a 4.4-million-year-old fossil skeleton to those of human and chimpanzee skeletons sheds light on our evolutionary history.
This interactive explores different anatomical features of the human body and what they reveal about the evolutionary history we share with other organisms, including earlier, long-extinct species.
One of the most exciting discoveries in the long history of fossil exploration is Tiktaalik, a creature with a mix of features common to fish and four-legged animals, or tetrapods.
Tiktaalik roseae, also known as the “fishapod,” is an animal that lived about 375 million years ago, with features of fish and four-legged animals.
The following classroom-ready resources complement Great Transitions: The Origin of Tetrapods, which tells the story of the discovery of Tiktaalik, a creature with features common to fish and four-legged animals, or tetrapods.
The skull of Zinjanthropus is one of the first early hominid fossils found in Africa and provides essential clues in the story of human evolution.
A reconstruction of Anchiornis huxleyi, a feathered dinosaur that is part of the ancestral lineage of birds.
Which traits distinguish humans from other primates? When and where did these traits evolve? Analysis of the major fossil finds from Africa, dating back to 4.4 million years ago, provides answers to these questions and reveal the history of our evolutionary origins.
