PREFACE
(popup menus in red)


Early in the book , WEiT expresses the following:

"The battle for evolution seems never-ending—a war between rationality and superstition." (p-xiii) [emphasis supplied]

followed by

"— this volume gives a succinct summary of why modern science recognizes evolution as true." (p-xiv) [emphasis supplied]

based on the verification of the following "Darwinism" features

--- it really consists of six components: evolution, gradualism, speciation, common ancestry, natural selection, and nonselective mechanisms of evolutuionary change. (p-3)[emphasis supplied]

WEiT's Figure 1 (below left) is an example of evolutionary biology's graphic depictions of Darwin's hypothesis of Descent From A Common ancestor.

The figure's diagrammatic organization of animal forms is typical of the science's universal expression of the progressive development of animal forms from the proposed common ancestor --- the divergent animal forms depending on "species splitting" at, for example, a common ancestor designated as node X.

The right-hand figure is WEiT's Figure 1 that has been edited to illustrate (sequences of blurred images) where, following the split, each species underwent "species-to-species" development via small trait modifications.

WEiT's Figure 1 illustrates this blog's argument concerning the common ancestry concept: species at a cladogram's node, tree diagrams, or textual descriptions (i.e., at WEiT's speciation/species splitting points), are not specified.

The following figure illustrates WEiT's concept of components and mechanisms associated with, for example, the X node in WEiT's Figure 1, or in other diagrammatic methods analogous branching points in phylogenetic trees.

This blog's primary goal is to document whether or not such "lineage snippets" coalesce into a comprehensive lineage that defines a Last Universal Common Ancestor.

If it can be demonstrated that that the Last Universal Common Ancestor concept is implausible, then the entire Darwinian hypothesis is implausible.
When unshackled from the restrictions imposed by the dogmatic common ancestry premise, the field's information base provides a variety of "morphological scenarios" upon which can be based plausible arguments on lineages sequence gaps that refute Darwinism's Last Universal Common Ancestor tenet.

The following figure summarizes the range of morphological conditions, and their relative presence in a time-line perspective, that comprise lineage gaps in the Last Universal Common Ancestor concept.

The critical aspect of each "morphological scenario" is referenced by a keyword that may or may not relate to one or more of WEiT's " Darwinism tenets".
