Human evolution

Resources:

Origins of humankind
This interactive timeline tells the story of 6 million years of hominid evolution through fossils, artifacts, and our branching family tree.
This resource appears at PBS's Evolution website.

Hall of Human Ancestors
This set of web resources includes an interactive family tree of hominids and our relatives, as well as a tool that allows users to view associated fossils and rotate them through 360 degree views.
This resource appears at the Smithsonian National Museum of Natural History website.

Origin of modern humans: Multiregional or out of Africa?  Advanced
Learn more about your own history from paleoanthropologist Donald Johanson. He describes how and when early humans evolved, Homo sapiens’ ancestors and relatives, and the diverse lines of evidence relating to this history.

Webcast: From butterflies to humans
In lecture four of a four part series, evolutionary biologist Sean Carroll uses the developmental genetics of insects to explain how old genes can learn new tricks and how this can help us understand human evolution.
This lecture is available from Howard Hughes' BioInteractive website.

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: Evolution in the fast lane?  Advanced
Have humans, with all of our technological advances, exempted ourselves from further evolution? Perhaps not. This news brief, from February 2008, examines genetic research which suggests that human evolution may haved actually accelerated in our recent history.

Evo in the news: Genealogy enthusiasts mine DNA for clues to evolutionary history  Advanced
This news brief, from November 2007, turns an evolutionary lens on businesses that use DNA for genealogy research and, in the process, illuminates what their genetic tests really track.

Evo in the news: Ghosts of epidemics past
HIV and malaria both constitute global health threats, respectively affecting more than 30 million and 200 million people worldwide. This news brief from October 2008 describes new research that reveals an unexpected evolutionary link between the two.

Evo in the news: Got lactase?  Advanced
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.

Evo in the news: Seeing the tree for the twigs  Advanced
Recent research has revealed that, in at least some ways, chimpanzees have evolved more than humans have. This news brief from May 2007 delves into this finding further and, in the process, debunks common misperceptions of human evolution.

Evo in the news: When it comes to evolution, headlines often get it wrong
Newly discovered fossils are prompting some scientists to consider a minor revision of the relationships shown on the human family tree. This news brief from September 2007 clarifies the occasionally misleading news coverage of the story.

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.
