Intelligent Design, the best explanation of Origins

This is my personal virtual library, where i collect information, which leads in my view to Intelligent Design as the best explanation of the origin of the physical Universe, life, and biodiversity

Principles of fascinating Virus Architecture: By evolution, or design ?

https://reasonandscience.catsboard.com/t3088-principles-of-virus-architecture-by-evolution-or-design

The complex arrangements of macromolecules in the virus shell are minute marvels of molecular architecture. Specific requirements of each type of virus have resulted in a fascinating apparent diversity of organisation and geometrical design. Nevertheless, there are certain common features and general principles of architecture that apply to all viruses.

The proposed spiral assembly pathway of large icosahedral capsids. Isosurfaces of CroV (A), PBCV-1 (B), and CIV (C) cryo-EM maps were centered on the 5-fold axis. Capsomers in all three panels are colored based on their orientation in red, blue, green, cyan, and orange. The pentameric capsomers are depicted as purple stars. (D) Schematic diagram showing the right-handed spiral assembly pathway following arrows (1) to (6), with multiple extensions (7) of the trisymmetrons to form similar patterns as shown in (A–C). One set of capsomers (red) is labeled by Roman numerals if they are part of the pentasymmetron and by Arabic numerals if they are part of a trisymmetron.
