1. Zimmer captures the reader's attention immediately, with a very effective title. "Lighting the Cambrian Fuse" evokes the feeling of something about to explode, like fireworks. When I read it I thought of lighting the fuse of a pack of fireworks, and the explosions that go with it. The title makes the reader (I did, anyway) want to know what it was that lit the "Cambrian Fuse."
2. Relating to our case study, this method is a good example of how important an introductory title can be. A good one makes the reader genuinely interested in hearing more, but a bad one can cause the reader to not really care, and not pay attention.
3. While Zimmer's method is more straight-forward non-fiction, Tobias uses more creativity in his hook. Honestly I'm not sure which approach I prefer as of now, because I want to have a better grasp on our topic to be able to present it in the most interesting and effective way.
4. A phylogeny is the study of the evolution of one specific organism or group of organisms. http://dictionary.reference.com/browse/phylogeny+
5. The Cambrian Explosion occurred between about 540 and 500 million years ago (Zimmer, 226, 227).
6. The Cambrian Explosion was so remarkable because it gives strong evidence to the theory of evolution on a large scale, and it was the first time symmetrical fossils were found, which are believed to be some of our oldest ancestors. http://www.actionbioscience.org/evolution/levinton.html
7. Some triggers that might have led to the Cambrian Explosion were genetic innovations, environmental factors, and ecological interactions. http://www.ncbi.nlm.nih.gov/pubmed/20074549

ReplyDeleteLovely work here. Great job citing sources, too. It may help to spend a little more time with the readings and a little less time doing Internet searches. That way, answers to questions like 6 can be more focused. That said, you are obviously engaging with the material and learning tons!
