This is good -- especially the 2nd article you linked to. It has some very strong arguments in favor of an evolutionary model as the basis for speciation within a genus, a family, or an order.
You still, however, have not shown how orders develop from other orders, or how classes from other classes, or how phyla are created from other phyla, or how animals originally developed from whatever their precursors were, or, for that matter, how single-celled organisms became multicellular organisms, or even how the first cell appeared. These are questions that must be answered for (random-mutation-based, selection-based) evolution to be shown as the single driving force behind life.
