Chapter 3 Sex and Nuclei: Eukaryotes

1. List of images for lectures
2. Substantial comments or mini-essays, often with links of their own. They are laid out in the order I deal with them in the Chapter.
3. Pages that consist almost entirely of Web links on a particular topic.
4. Small comments and asides ("footnotes", if you like), including useless information, again arranged in order. I have listed them under page number as well as topic.

Footnotes

• Page 31. The largest bacterium. Bacteria are almost always smaller than eukaryotes. But evolution and natural selection don't pay attention to the generalizations that humans use to describe the real world. You can't always trust size! The largest bacterium ever discovered was described in 1999, Thiomargarita namibiensis. Here are some news articles:
  • New York Times
  • Science News.
• Some basal eukaryotes
