|Pandora by Dante Gabriel Rossetti, 1879|
Viruses in many ways are an enigma to biologists. Debate has raged for years as to whether viruses can even be considered a life form. As they lack the enzyme and organelle ‘machinery’ that defines a living cell, viruses cannot carry out the necessary internal metabolism to sustain life, or to reproduce themselves. It’s true that they carry their own genes (the DNA or RNA ‘blueprint’ that codes for their construction). However, viruses can only reproduce by commandeering a suitable host’s cell machinery to do the job. Viruses therefore can in no way be presented by evolutionists as a transitional form (i.e. an ‘evolutionary intermediate’) between non-life and life, as viruses need to have fully-functional living cellular organisms already in existence! Viruses do not really fit anywhere on the evolutionary ‘tree of life’—they are very obviously not the ancestors of one-celled (or any other) creatures.To read the rest, click on "Pandoraviruses: a Pandora’s Box of trouble for evolution".
