Evolution Is Not Random (At Least, Not Totally)
Evolution is often said to be "blind," because there's no outside force guiding natural selection. But changes in genetic material that occur at the molecular level are not entirely random, a new study suggests. These mutations are guided by both the physical properties of the genetic code and the need to preserve the critical function of proteins, the researchers said.
DNA is made up of a sequence of letters, or amino acids, which encode proteins, the structures that carry out important jobs inside cells. Conventional wisdom states that evolution occurs by random mutations that make an individual organism better able to survive and reproduce, according to natural selection.
In the study, published Sept. 30 in the journal Royal Society Open Science, fisheries biologists Michael Garvin and his colleague Anthony Gharrett, of the University of Alaska Fairbanks, in Juneau, set out to see whether or not these mutations were truly random.

Re: Evolution Is Not Random (At Least, Not Totally)
It's kind of like showing how space tends to "organize" itself into "systems" of smaller bodies orbiting larger bodies because of gravity. There's nothing actually guiding evolution but there are physical laws affecting it.
