Two replies to the insufferable Jim Downard:
On avoiding design inferences:
Before you infer intelligent design, keep in mind that grass-cutting shears share an extremely high similarity with scissors which are used to cut paper. Since a paper stencil was apparently used in the origination of the grass-pattern, itÃ¢â‚¬â„¢s likely that a pair of scissors was used to cut the stencil. This makes it plausible to assume that the grass-cutting shears were co-opted from scissors, because both are clearly homologous structures based upon their similarity. Moreover, paper is made of plant material, and grass a plant. This could account for the origin of the stencil itself. Finally, Virginia has metal resources which could account for the origin of the original scissors. DonÃ¢â‚¬â„¢t use a science-stopping explanation and infer design! WeÃ¢â‚¬â„¢re Ã¢â‚¬Å“on our wayÃ¢â‚¬Â to figuring this out, so donÃ¢â‚¬â„¢t threaten the progress of science, medicine, and all of civilization by saying this was designed! You might as well reject round earth “theory” and the Periodic Table!
