Evolution Takes A Hot Bath As Archaea Migrate
Athens GA (SPX) Jun 14, 2006 Since their discovery in the late 1970s, microorganisms known as archaea have fascinated scientists with their ability to thrive where no other life can - in conditions that are extremely hot, acidic or salty. http://www.terradaily.com/reports/Evolutio...ea_Migrate.html Parallel Evolution Found To Exist At Protein Level by Staff Writers Ann Arbor MI (SPX) Jun 14, 2006 Wings, spines, saber-like teeth-nature and the fossil record abound with examples of structures so useful they've evolved independently in a variety of animals. But scientists have debated whether examples of so-called adaptive, parallel evolution also can be found at the level of genes and proteins. http://www.terradaily.com/reports/Parallel...tein_Level.html -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
