After three hours of contentious debate, the Hawaii Board of Education voted unanimously to keep evolution as the only theory of human origin taught in the state's classrooms.
Darwin, who once wrote that species were "indefinable," might have described a species as a segment of a branch on the ever-expanding tree of life, the same tree he drew as the only figure in the "Origin".
Such trees have been around for some time; Darwin (1859) included one as the only illustration in the Origin.
Most paleontologists regard birds as the only surviving dinosaurs (see Origin of birds).
We have suggested two alternative explanations for the obser vation of monotypism which we believe must be shown to be invalid before accept ing monoclonal origin as the only plausible way to account for the observed G-6-PD monotypism.
Darwin clearly considered this Tree of Life as an important organizing principle in understanding the concept of "descent with modification" (what we now call evolution), having used a branching diagram of relatedness early in his exploration of the question (Fig. 1) and including a tree-like diagram as the only illustration in On the Origin of Species (Darwin 1859).
"It's unfortunate that we'll now be forced to again teach evolution as the only possible explanation for the origin of life, even though it's a lame explanation with very little scientific support," says certified public accountant John Bacon, one of the two pro-ID candidates who won the primaries on Tuesday.
Charles Darwin later drafted his first branching diagram in a research notebook (1837) before publishing a phylogenetic tree as the only illustration in On the Origin of Species by Means of Natural Selection (1859) to describe descent with modification, or what is now known as evolution.
Multivariate analysis identified evidence of tumour origin from MALT as the only factor to attain prognostic significance in patients with gastric involvement, and clinical stage and the presence of MHI as the only factors to attain prognostic significance in patients with intestinal involvement.
Warren of Stafford, whose origins parallel the birth of the textile industry in New England, has been reborn as the only United States affiliate of the Loro Piana company.
