We learned many things about fossil evidence and evolution today. For those of you who would like to further your knowledge about this topic, below are some links you might want to check out.
1. T-Rex Blood
This was the NovaScienceNow video clip Ms. Gwen showed in class on Friday. For those of you who want to see the full clip, here it is.
2. Archaeopteryx feather color
One of my students asked if scientists have actually genetically engineered a woolly mammoth-elephant hybrid. As of January 2011, the answer is "no." If you find a more recent article (from a credible source), bring it up and you can present it to the class for extra credit. See details below and on the "Extra Credit" section under the "Documents" tab.
4. Tiktaalik roseae
This is a website maintained by the University of Chicago. You can click on some of the tabs at the top to learn more about this transitional fossil. In class, Ms. Gwen said that 3 fossils of Tiktaalik have been discovered. That is outdated information. The University of Chicago lists the number of uncovered specimens to be 10!
5. Charles Darwin
This is a NOVA/National Geographic documentary that gives you some context and background about Darwin and his times. In class, Ms. Gwen told you that there was another scientist who independently came up with the idea of natural selection. She mis-recalled his name as "Walton." It was actually "Wallace...Alfred Russel Wallace." You can read more about it here: Natural Selection: Darwin and Wallace (University of California, Berkeley).
If you find recent news or science articles that relate to what we are learning in class, you may ask to present it to the class for extra credit. This extra credit option is like Ms. Babiuk's "stump the teacher" extra credit and will be open throughout the semester. In a presentation that is about 5 minutes long, present to the class the following: (1) the title of your article, (2) the source of the article and when it was written, (3) the major findings of the article, (4) the implications of these findings, i.e., why this is important, and (5) your evaluation of the article's merits and shortcomings. You may present only once and if you fulfill all the requirements, you will earn 5 extra credit points to be contributed to your Test grade. You may not do both "stump the teacher" and "present a science article" as extra credit.

2. Archaeopteryx feather color
This is a pretty recent finding, published in January 24, 2012 (only a couple weeks ago). Artists often illustrate pictures of archaeopteryx with colorful feathers. However, scientists at National Geographic have evidence that this transitional animal had feathers that were black. (Here is a related article about dinosaur colors.)
3. Woolly Mammoth DNAOne of my students asked if scientists have actually genetically engineered a woolly mammoth-elephant hybrid. As of January 2011, the answer is "no." If you find a more recent article (from a credible source), bring it up and you can present it to the class for extra credit.
