Harry Whittington Dies 94
Published: 5:58PM BST 08 Aug 2010 Professor Harry Whittington Professor Harry Whittington, who died on June 20 aged 94, was the former Woodwardian Professor of Geology at Cambridge and the world’s leading authority on fossil trilobites; in later life he led painstaking research which revealed a “Cambrian explosion” and raised disturbing questions about the proCesses of evolution. Trilobites were hard-carapaced creatures, which thrived, in the Cambrian period, beginning 542 million years ago, until they died out nearly 300 million years later. Very distantly related to horseshoe crabs, they lived in the sea and crawled on land, evolving into more than 20,000 different species, ranging in size from a millimetre to nearly two feet. Many known species are ones which Whittington himself discovered on field trips around the world. Usually it is difficult to extract the fossils from the surrounding rock, but in the 1940s Whittington and his colleague Bill Evitt investigated beds in Virginia where the carapaces of the animals had been replaced by insoluble silica. By throwing samples into acid, they were able to recover thousands of perfect specimens, ranging from fully-grown adults to microscopic larvae. These fossils enabled Whittington, in a series of monographs published in the 1950s and 1960s, to revolutionize what we know about trilobites — how they grew from larva to maturity through successive molts, how they moved and articulated their bodies, and how they evolved and migrated. Later in his career, in 1966, Whittington was invited by the Canadian Geological Society to chair a group commissioned to examine the Burgess Shale deposits discovered by CD Walcott during the building of the Canadian Pacific Railway in 1909. -
THE SYNTHETIC THEORY of EVOLUTION DNA Makes RNA, RNA Makes Protein and Proteins Make Us
320 Chapter f THE AGE OF MAMMALS The Present is the Key to the Past: HUGH RANCE THE SYNTHETIC THEORY OF EVOLUTION DNA makes RNA, RNA makes protein and proteins make us. —Crick.1 f14 Genes, alleles < deoxyribonucleic acid > ...using the metaphor of computation to describe the role of genes is bad biology, for it implies an internal self-sufficiency of DNA. Even if we had the complete DNA sequence of an organism and unlimited computational power, we could not compute an organism, because an organism does not compute itself from its genes. (In fact, any computer that did as poor a job of computation as a genetic “program” does of an organism would immediately be thrown into the trash.) —Richard Lewontin The Triple Helix: Gene, Organism, and Environment, 2000.2 Mathematical population theorists Ronald Aylmer Fisher (The Genetical Theory of Natural Selection, 1930),3 John Burdon Sanderson Haldane (design disparaging: “[He has] an inordinate fondness for beetles.”),4 and Sewall Wright (conceiver of “adaptive landscapes”)5 were the principle forgers, during the period 1920-1950, of the modern theory of population genetics that unites previously warring concepts (Footnote f14.1) of Darwinian natural selection, which is decidedly nonrandom, that guides evolution incrementally (by gradual change) but rapidly by its recursiveness (the output of previous selection is input for subsequent selection), along paths to fitness, and the purely random nature (no inherent directionality, no predictability) of heredity by large sudden changes (saltations, hopeful monsters) that Mendelian rules suggested to some geneticists (principally, typologists William Bateson, Hugo de Vries, and Wilhelm Johannsen). -

Aguillard, the United States Supreme Court declared unconstitutional a Louisiana statute (the Bal- anced-Treatment Act) that required the state's public schools to teach Creationism if evolution was taught and to teach evolution if Creationism was taught.' That decision was the culmination of a series of court battles and cultural conflicts that can be traced back to the famous Scopes Trial of 1925 in Dayton, Tennessee.2 Although many thought, and continue to think, that Edwards ended the debate over the teaching of origins in public schools, a t This article is adapted from FRANCISJ.

A Response to the Boyle Lecture by Simon Conway Morris
S & CB (2006), 18, 31–34 0954–4194 JOHN POLKINGHORNE Rich Reality: a response to the Boyle Lecture by Simon Conway Morris Simon Conway Morris’s Boyle Lecture delivers a rhetorically lively and intel- lectually provocative challenge to scientistic fundamentalism and its assertively arid discourse. He rightly criticises the tone of the arguments pre- sented by people such as Richard Dawkins and Daniel Dennett, pointing out that in relation to religious belief they treat serious issues ‘with a bluntness and unsubtlety that in any normal discourse would be treated as juvenile’. There is indeed a deplorably ‘know-nothing’ character in some of the writings abut science and religion that originate from the sceptics, in which the authors totally fail to engage with the intellectual integrity and truth-seeking charac- ter of theological thought. Conway Morris’s response certainly does not suffer from the ‘combination of nervousness and accommodation’ that he – unfairly in my opinion – says characterises much of the religious participation in debate. The lecturer believes that his own subject of organic evolution is the topic that is ‘the most sensitive, in some ways the most vulnerable’ in this dialogue. I would want to add to that the equally important discussion of the exchanges taking place across the frontier between neuroscience and theological anthro- pology, since they too impinge significantly on the question of the nature and significance of the human person. Yet no one could deny the importance of a temperate and truthful engagement between evolutionary insight and the doc- trine of creation, so that a Boyle Lecture given by a distinguished palaeontolo- gist who tackles these issues with frankness and discernment is greatly to be welcomed. -
A Deeper Look at the Origin of Life by Bob Davis
A Deeper Look at the Origin of Life By Bob Davis Every major society from every age in history has had its own story about its origins. For instance, the Eskimos attributed their existence to a raven. The ancient Germanic peoples of Scandinavia believed their creator—Ymir—emerged from ice and fire, was nourished by a cow, and ultimately gave rise to the human race. Those are just two examples. But no matter the details, these origin stories always endeavor to answer people’s innate questions: Where did we come from? What is our destiny? What is our purpose? Two widely held theories in today’s world are abiogenesis and the Genesis story. The first states that life emerged through nature without any divine guidance; the second involves a supernatural Creator. Abiogenesis Abiogenesis is sometimes called “chemical evolution” because it seeks to explain how non-living (“abio”) substances gave rise to life (“genesis”). Abiogenesis was added to the list of origin stories over one hundred years ago when Charles Darwin first speculated that life could have begun in a “warm little pond, with all sorts of ammonia and phosphoric salts, lights, heat, electricity, etc. present, so that a protein compound was chemically formed ready to undergo still more complex changes.”1 Many summarize abiogenesis—coupled with its more famous twin, Darwinian macroevolution—in a somewhat disparaging but memorable way: “From the goo to you by way of the zoo!”2 Let’s use this phrase to help us understand what is meant by “abiogenesis.” The “goo” refers to the “primordial soup” or “warm little pond” where non-life is said to have given birth to life. -
