One long argument
Ernst Mayr, the renowned evolutionary biologist and champion of Darwin, celebrated his 100 th birthday earlier this month by leading a scathing attack on creationism. The evolutionary biologist, acclaimed as one of the most prolific researchers, has no intention of retiring and is shortly to publish new research that dismantles the fashionable creationist doctrine of 'intelligent design'. Altho...
متن کاملOne Very Long Argument
The distribution of organisms in morphologic space is clumpy. Cats are like felids, dogs are like canids and snails are (mostly) like gastropods. But cats are not like dogs and snails are not like clams. This clumpy distribution of morphology has long posed one of the greatest challenges to evolutionary biologists. Does it represent the extinction and disappearance of a once-continuous distribu...
متن کاملStreptococcus pneumoniae and its bacteriophages: one long argument.
Infectious diseases currently kill more than 15 million people annually, and the WHO estimates that every year 1.6 million people die from pneumococcal diseases. Streptococcus pneumoniae (pneumococcus), a bacterium with a long biological pedigree, best illustrates the rapid evolution of antibiotic resistance, which has led to major public health concern. This article discusses the molecular bas...
متن کاملVizing's conjecture and the one-half argument
The domination number of a graph G is the smallest order, γ(G), of a dominating set for G. A conjecture of V. G. Vizing [5] states that for every pair of graphs G and H, γ(G H) ≥ γ(G)γ(H), where G H denotes the Cartesian product of G and H. We show that if the vertex set of G can be partitioned in a certain way then the above inequality holds for every graph H. The class of graphs G which have ...
متن کاملOne Long Argument. Charles Darwin and the Genesis of Modern Evolutionary Thought
these limitations, the thoroughness of the book still shines, and both clinicians and researchers will benefit from having this concise volume. pp. $8.95. Charles Darwin was not the first biologist to consider the possibility that living beings might have evolved from earlier precursors, but he was the first to develop a radical concept of the nature of evolution and to organize supporting evid...
