New developments which tie into topics you've brought up before:
1) Recent (or current) mutations in humans:
Lactose tolerance is a recent mutation and confers advantage to humans over the default lactose intolerance.
2) "Junk" DNA:
Biological dark matter.
3) Epigenetics...I'm too lazy to look these up, but two recent articles, either in Science or Nature, one discussing maternal finch influence in chick gender sex selection and another discussing maternal influence in gene expression in murine cloning experiments. Both interesting articles. If I remember correctly, you have access to Nature. I'll assume you have access to Science as well.
I'd often wondered about the very high incidence of lactose intolerance among orientals and the lack of diary products in Chinese food. Clearly, that's no coincidence but what, I wondered, is the cause and what is the result? Now, it seems we know. The intolerance dictated the diet and not vice-versa.
