Yuccas Of The Southwestern
United States: A Study In Numerical Taxonomy And In Origins At The
George F. Howe, Ph.D.
The lily family in general
and the Yucca genus in particular are discussed in the context of origins.
Eleven criteria are presented by which species in the genus Yucca may
be compared. Nine Yucca species are contrasted using these same criteria.
The results are then subjected to numerical taxonomy by which three
subgroups or "sections" are established in the genus Yucca
rather than the usual four sections proposed by other workers. Furthermore,
it is asserted that the origin of these sections and species in the
genus Yucca is not easily explained by evolutionary descent within the
genus. The data of paleobotany and pollination also fail to support
the origin of Yucca species by evolution. It is a credible alternative
to evolution to suggest that the Creator endowed each particular group
with its own assemblage of morphological characteristics.
Stereochemical Design In
Gerald B. Heyes, B.A.
Creationists have successfully
challenged evolutionists with the evidence of clever engineering design
in optically active isomers such as the L-amino acids and D-sugars found
exclusively in life forms. That these resolved isomers cannot be synthesized
or maintained in significant quantities outside of living organisms
has been recognized as strong evidence against any spontaneous generation
of biopolymers from some primeval broth.
Nevertheless, the evidence
found in geometric isomers is largely unknown in spite of the critical
role played by this sort of stereoisomerism in living cells. Some biolipids
found in cell membranes (phospholipids) are always in the cis-same side-configuration.
While this geometry is essential for the proper functioning of cell
membranes, it turns out that this cis configuration is not what we would
expect to find in nature because it is the higher energy form. The trans-opposite
side-configuration is the lower energy form and thus would be expected
to be found.
A creationist teleological
(planning and purpose apparent in design) explanation seems to be demanded
by these facts. It is true that certain low probability molecules can
be synthesized in the laboratory, such as certain substituted benzene
ring isomers or even cis-polyethylene. However, these only serve to
buttress the teleological argument since they require intelligence in
planning the synthesis, fabricating and arranging the complex apparatus,
environmental control, and in carrying out the stepwise chemical reactions
in the presence of highly specific reagents, using controlled (not random)
Further, the phyletic distribution
of many biolipids may very well follow a mosaic pattern previously alluded
to by some creationists.
Earth's Young Magnetic Age
Thomas G. Barnes, D.Sc.
The depletion of the earth's
magnetic field is documented in scientific literature. This field shields
the earth from some of the cosmic rays. The depletion of this shield
has two side effects: 1) harmful biological effects, and 2) lowering
the carbon-14 dates. The decay preocess is explained in terms of an
equivalent circuit, providing simple solutions for the decay process.
The theory and data are employed to set a limit on the age of the earth's
magnet and, by inference, the age of the earth. Three independent checks
provide confirmation of the theory.
