La Brea Tar Pits: An Introductory History (17691969)
William Weston
In the first two decades of the twentieth century, hundreds of thousands
of fossils were excavated from the Rancho La Brea Tar Pits. Prior to
that time, these pits were unknown. When Spanish settlers first arrived
in the area of Los Angeles in the eighteenth century, they found a number
of tar springs located in the middle of a large plain at the foot of
the Santa Monica Mountains. Surrounding the springs was a scattering
of animal bones visibly embedded within a layer of asphalt. It was not
until the mid 1870s that people began to realize the remote antiquity
of these bones. Soon after exploratory excavations began in the early
1900s, scientists were finding tar pits containing large numbers of
fossils.
The conventional explanation for the occurrence of these fossils is
that thirsty birds and mammals, deceived by water-filled pools of tar,
had blundered into these viscous traps and died in them. Although widely
accepted, the entrapment theory has failed to give convincing answers
to some key evidentiary questions, including the physical characteristics
of tar pits, the fragmentation and chaotic intermingling of the bones,
and the numerical preponderance of the carnivores. Since these issues
cannot be adequately resolved by the entrapment theory, then a new explanation
is needed. The evidence seems to be pointing toward the possibility
of a single catastrophic flood as the agent for fossil deposition at
the La Brea Tar Pits.
Why Mutations are Lethal to Darwinism
Jerry Bergman
The primary means by which evolution is believed to occur are mutations,
independent assortment of genes, gene shuffling and natural selection.
Mutations are non-directed DNA changes that can be expressed in the
offsprings phenotype and passed on to the organisms progeny.
Unrepaired mutational genetic changes are relatively rare, however,
occurring only about once per billion DNA bases. For natural selection
to operate, there would need to be biological variants from which to
select, and these differences must ultimately be provided only by mutations
in the macroevolutionary scenario. A review of many types of mutations,
however, indicates that they cannot provide the raw material necessary
for natural selection for various reasons. Consequently, evolutionary
naturalism still lacks a mechanism to produce new information and biological
novelty.
Vision
Don B. DeYoung
For mankind as well as for the animal world, eyesight is a compelling
testimony to creative design. Continuing research reveals the complexity
of vision for every creature, whether living in the past or present.
This article reviews recent studies of eyesight in people, trilobites,
parasites, and dinosaurs.
The Crucial Importance of Epistemology and Correctly
Defining Science
for the Cause of Creation and Intelligent Design
Robert E. Kofahl
In the creation/evolution debate much misunderstanding and error arise
from differing definitions of science and conflicting epistemologies.
Creationists rightly hold secularists guilty of distorting the definition
of science by injecting it with their epistemology and their assumption
of a closed materialistic universe. Conversely, some Christians would
inject their belief in God and His miraculous works into scientific
hypotheses, calling it theistic science. Some in the Intelligent
Design (ID) movement develop this further, classifying intelligent design
as a scientific concept. The application of philosopher of science Karl
Poppers criterion of demarcation and the process of
conjectures and refutations is proposed to correct these
errors.
