Guess what? Natural selection still works. The widespread use of Roundup, the weedkiller, has led to the appearance of Roundup-resistant strains of weeds, according to Business Week.
Politics: (sort of -- I don't have a category for this) The New York Times has reviewed an important new book on the subject of why marriage is less frequent among blacks than whites, in the U. S. The book's title is Is Marriage For White People? How the African American Marriage Decline Affects Everyone. The review is also an analysis of the issue.
(or maybe Science) Wired reports on the new patent legislation. The reported indicates that the new law is an improvement, but is still less than thrilled, saying that it gives advantages to corporations, rather than individual inventors..

I read somewhere that daylilly and heat resistant grass pollens mixing in with weeds is a major cause of "weed killer resistance".
I would imagine with weeds, it only takes a few seasons because one season is several generations.
Thanks, atlibertytosay.
That would depend on the weed. Poke salad, for example, has only one generation per year. I think most weed plants are like that.

I hadn't read that, Patton, but it may well be so. Thanks!
