Found 24 resources for the concept: Evolutionary trees (i.e., phylogenies or cladograms) portray hypotheses about evolutionary relationships
 | Eye Evolution
This worksheet guides students through an interactive online module entitled Why the Eye? on the Understanding Evolution website. Students gain a better understanding of the different types of animal eyes and how natural selection can account for the evolution of a complex organ.

 | Evo in the news: Quick bites and quirky adaptations
Trap-jaw ants made headlines with the record-breaking speed of their jaws and a quirky behavior: flinging themselves into the air using the power of their mandibles. This news brief from October 2006 reveals the evolutionary story behind the headlines.

 | Evo in the news: Evolutionary evidence takes the stand
This news brief, from January of 2007, describes the role of phylogenetic evidence in a Libyan court case. Six medical workers have been convicted of injecting children with HIV-tainted blood - but the evolutionary history of the virus paints a different picture.

 | Evo in the news: Happy 200th, Darwin!
This news brief, from February 2009, celebrates Darwin's bicentennial by examining what we've learned about the evolution of the Galapagos finches since Darwin's time.

 | Evo in the news: Tough conservation choices? Ask evolution
The earth is facing a biodiversity crisis. Nearly 50% of animal and plant species could disappear within our lifetime. To stem this rapid loss of biodiversity, we'll need to act quickly -- but where should we begin? This news brief, from December 2008, explains how evolutionary history can help us set conservation priorities.

 | Evo in the news: Making sense of ancient hominin DNA
In March 2010 German researchers announced that they had managed to extract DNA from the 40,000 year old fossil bone from a child discovered in a Siberian cave and that it didn't match up to the known genetic sequences of either humans or Neanderthals! This news brief examines the evidence in more detail and considers what that evidence might — or might not — mean about such claims.

 | Evo in the news: Spreading disease on evolutionary timescales
Most infectious diseases that we are familiar with are passed from human to human; however, on evolutionary timescales, pathogens don't necessarily respect species boundaries. This news brief from November 2010 examines a recently discovered case of disease swapping among species involving a deadly strain of malaria.

 | Why the eye?
Eyes are something of an icon of evolution. How did such an integrated, multi-part adaptation evolve? While many different animals have complex eyes, untangling their evolutionary history reveals both remarkable diversity and surprising similarity.

 | Phylogenetics and tree thinking slide set
This set of five PowerPoint slides featuring personal response questions (i.e., multiple choice questions that can be used with "clicker" technology) can be incorporated into lectures on the mechanisms of evolution in order to actively engage students in thinking about evolution.

 | Tree thinking basics
Tree thinking, or phylogenetics, is an important way of understanding evolutionary relationships. Reading trees correctly can pose some challenges. This video introduces the basics of three reading and addresses common problems in tree reading.
