Evolution above the Species Level
All handouts were actually done on a CD-Rom, the contents of which are also available online at http://eog.nescent.org/NABTsymposium.htm. Eventually, PowerPoint presentations and audio files of the text of the speakers will be made available by the AIBS. Their availability will be posted on that site..
Evo-Devo to the Classroom: Macroevolution Happening!
Dr. Platt presented several experimental examples that illustrate the influence of DRGs (Developmental Regulatory Genes), either by over-expression or under-expression. Pictured results were shown, and students were asked to draw inferences, reach conclusions, or form hypotheses, each followed by professional responses and confirmations.
If you would like to see Dr. Platt's PowerPoint (for personal professional growth, and/or possibly for showing to your high school biology students), he has kindly consented to make it available on an individual basis. If you are interested, please email your request, and how you intend to use it, to the ENSI webmaster.
Click Here for the list of References that Dr. Platt provided at his session.
Don't forget the useful article in the January 2006 American Biology Teacher "Macroevolution: Alive and Well In Sticklebacks" by Dr. Jaames Platt.
Read the excellent article in the NY Times Science section, with recent developments (2007) in Evo Devo. Click HERE to read the review and get the links. Includes a link to an excellent video clip by Sean Carroll, very useful for explaining EvoDevo to students.
See the Evo-Devo page here on the ENSI site, where you will find even more resources, including links to useful books on EvoDevo.
And check out our long list of ENSI lessons for teaching Speciation and Macroevolution.

The online version does not have the nice sketches that the magazine does, but it does have photos of a variety of organisms in the Photo Gallery side bar (that could be used to make a PowerPoint slide show). And in the "Learn More" area, check the link to an interesting essay by Sean Carroll (author of Endless Forms Most Beautiful), or go directly to it at: http://www.hhmi.org/research/investigators/carroll.html
Here are some excerpts from the online text of A FIN is

"The father of evolution was a nervous parent. Few things worried Charles Darwin more than the challenge of explaining how nature's most complex structures, such as the eye, came to be. 'The eye to this day gives me a cold shudder,' he wrote to a friend in 1860."
"Today biologists are beginning to understand the origins of life's complexity-the exquisite optical mechanism of the eye, the masterly engineering of the arm, the architecture of a flower or a feather, the choreography that allows trillions of cells to cooperate in a single organism."
"The fundamental answer is clear: In one way or another, all these wonders evolved. "The basic idea of evolution is so elegant, so beautiful, so simple."
"A limb, a feather, or a flower is a marvel, but not
If you develop any kind of interactive lesson or activity that effectively presents the concept, examples and evidence for macroevolution, especially lessons involving Evo-Devo, please share with ENSIWEB, and we will add it to our collection, freely available to teachers everywhere.
