POPSReverse evolution in real-time These findings provide further insights into the basic understanding of how evolution and diversity are generated and maintained. On the one hand, it provides evidence for evolution happening through changes in the distribution of alleles in a population (so-called standing genetic variation), from generation to generation, rather than the appearance of mutations, from one generation to the next. On the other hand, as Henrique notes, 'It has implications for the definition of biodiversity: some of the 'reversed' flies may be phenotypically identical to the ancestral flies, but they are genetically different. How then do we define biodiversity?' interesting experiments.

POPSOn the Origin of Species
A must read. "the Struggle for Existence amongst all organic beings throughout the world, which inevitably follows from their high geometrical powers of increase, will be treated of. This is the doctrine of Malthus, applied to the whole animal and vegetable kingdoms. As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected. From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form. This fundamental subject of Natural Selection" "namely, that each species has been independently created - is erroneous. I am fully convinced that species are not immutable" The first of our six abridged extracts; can't wait for the res

POPSThe blurry line between life, nonlife Twitches of life are showing up where life shouldn't exist. In southern Africa, for example, scientists burrowed 2 miles beneath the earth's surface,discovering bacteria that feed on radioactive rocks. "That's crazier than any science fiction," said Pratt, part of the team that made the 2006 discovery. "This is life that shouldn't be there. Except it is." interesting concept.

POPSIsraeli PM Ehud Olmert Claims to be Able to Order Bush Around Olmert reports that Bush had no idea what the substance of the resolution was, and this anecdote is consistent with what we know about how this White House has functioned. Bush admitted to Bob Woodward that an important decision on sending some troops to Iraq had been made by National Security Adviser Stephen Hadley and that Bush had not sat in on the relevant meetings. So Rice was at the UN on her own, thinking she was a plenipotentiary of Bush, and Olmert was annoyed at this attitude and decided to put her in her place.

POPSBush Ordered Rice Not To Vote on Her Own Resolution “In the night between Thursday and Friday, when the secretary of state wanted to lead the vote on a ceasefire at the Security Council, we did not want her to vote in favour,” Olmert said. “I said ‘get me President Bush on the phone’. They said he was in the middle of giving a speech in Philadelphia. I said I didn’t care. ‘I need to talk to him now’. He got off the podium and spoke to me. “I told him the United States could not vote in favour. It cannot vote in favour of such a resolution. He immediately called the secretary of state and told her not to vote in favour.”
