Lucy’s butcher, doggy diversity, the myth of Rome, and more!
Did the friends and family of supposed ape-woman “Lucy” use tools to butcher meat for meals?
Evolutionists continue to speculate about where life began. The latest answer? Between sheets of the geological substance mica.
Last week we discussed the domestic dog’s ability to illustrate how natural and artificial selection fit perfectly in the creation/kinds framework.
This week, the story turns to doggy genetics, the basis for the diversity we see among our canine friends. Researchers led by geneticists Carlos Bustamante of Stanford University and Elaine Ostrander of the National Human Genome Research Institute have been busy analyzing genetic data taken from domestic dogs—915 dogs, to be exact, which represent 80 breeds. The scientists hoped to better understand how many genes it takes to produce the broad doggy diversity we see—size, fur length and color, skull shape, and more.
The data indicate that 51 genetic regions govern the physical features that vary between dog breeds. But what’s more amazing is that of these 51, a mere six or fewer of the regions can explain some 80 percent of the variation.
ScienceNOW’s Michael Price, citing University of Tennessee–Knoxville geneticist Jeffrey Phillips, notes, “The study validates the idea that a relatively small amount of genetic variance can lead to a large degree of physical diversity.” The research thus serves as an important reminder of the plausibility of getting a great deal of biological diversity—all that we see today—in just a few thousand years, since the global Flood. By pairing up the creation model of kinds with all we know about genetics, selection, and speciation, the diversity of life makes perfect sense.
Have scientists found the oldest pieces of the earth?
Lava rocks from the Arctic may be the oldest known pieces of the planet, according to a team of scientists reporting in the journal Nature. The rocks were recovered from Greenland and from Canada’s Baffin Island by a team including Boston University earth scientist Matthew Jackson.
The basis for the claim about the rocks’ age is chemistry. Although the scientists believe the rocks were ejected volcanically “only” 60 million years ago, the team discovered chemical signatures that suggest an age of nearly 4.5 billion years old—only slightly less than the earth’s purported age. That places the rocks’ existence before the earth’s crust had formed, during a time that one scientist calls “a key phase in the evolution of the earth [that] set the stage for everything that came after.”
Creationists have a number of reasons to question our ability to use a rock’s internal chemistry to accurately establish its date of origin; such an ability is predicated upon key uniformitarian assumptions that are incompatible with biblical history (e.g., constant radioactive decay at today’s slow rates). As for earth’s supposed evolutionary formation and the internal behavior, scientists continue to face riddle after riddle, the answers to which are often based on the same uniformitarian assumptions.
Is denying evolution “like . . . ignoring the exquisite ruins of the Roman Colosseum”?
