For Biology 101, *Life* by David Sadava is amazing. I wasn't even particularly interested in the subject and just needed the course credit, but it was a fascinating page turner and made everything so clear. https://www.amazon.com/Life-Science-Biology-David-Sadava/dp/1464141266 I don't know if this counts as a textbook, but *Python for the Absolute Beginner* is so good for beginning programming. Python is a great language to learn programming with. This book is just so perfectly paced. It's the exercises that make it work so well. It increments the difficulty just a smidgeon with each exercise to gradually get you used to more and more concepts. https://www.amazon.com/Python-Programming-Absolute-Beginner-3rd/dp/B00B7RE628/ref=sr_1_1?s=books&ie=UTF8&qid=1470565643&sr=1-1&keywords=python+for+absolute+beginners#navbar

> lower-status husband Interesting I have seen research that suggests a major difference in perceptions between men and women. Men tend to assess the average woman as, well, average in overall attractiveness. Women tend to assess about 80% of men as below average. So in a monogamous society women tend to think they have settled too low. Such a gap in perceptions would make sense in a polygamous society where a few men at the top have most of the women - so the women marry up, and end up perceiving this as normal. From my reading, most hunter gatherer societies were polygamous.

Well if the pattern was too complicated, then a reader of the blog post wouldn't be able to notice it.
