Sorry, no etymologies found.
The false theory of evolution is called the monophyletic, which teaches that all species of plants and animals including man, developed from one cell or germ which came by creation or spontaneous generation.
Are we not compelled to adopt what is called the monophyletic hypothesis, that is, that our line of descent started from one pair, male and female, somewhere in the vast stretch of geologic or biologic time, and to reason that, had that pair been out of the race, we should not have appeared?
Hennig's idea that groups of organisms, or taxa, should be recognized and formally named only in cases where they are evolutionarily real entities, that is "monophyletic", at first was controversial.
I realize this interpretation is anathema to the Darwnian monophyletic mindset but that does not mean that it is wrong.
The monophyletic Darwinian model is without foundation.
I was going to direct ID guy's attention to Figure 8 in Knox's paper, that shows how clades can be nested by forming increasingly inclusive monophyletic groups.
Hierarchy I is non-nested, all entities are species, and first life equally well represents the progenitor of all life or of some restricted monophyletic group. and
Hierarchy II represents the monophyletic grouping of terminal species (Fig. 3b), and this has been rotated and shifted to a new position (Fig. 5g), with shading added to highlight sister-groups.
Hierarchy I is non-nested, all entities are species, and first life equally well represents the progenitor of all life or of some restricted monophyletic group.
Except a monophyletic groups is so called based on shared characteristics.
