This isn’t news, but until now the creationists have been silent about it. The gene that makes all the difference between our brains and those of our cousins, the chimps, was identified, according to this article from two years ago at Medical Xpress: A gene for brain size only found in humans. It says:
About 99 percent of human genes are shared with chimpanzees. Only the small remainder sets us apart. However, we have one important difference: The brain of humans is three times as big as the chimpanzee brain. During evolution our genome must have changed in order to trigger such brain growth. Wieland Huttner, Director and Research Group Leader a the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG), and his team identified for the first time a gene that is only present in humans and contributes to the reproduction of basal brain stem cells, triggering a folding of the neocortex.
The researchers isolated different subpopulations of human brain stem cells and precisely identified, which genes are active in which cell type. In doing so, they noticed the gene ARHGAP11B: it is only found in humans and in our closest relatives, the Neanderthals and Denisova-Humans, but not in chimpanzees. This gene manages to trigger brain stem cells to form a bigger pool of stem cells. In that way, during brain development more neurons can arise and the cerebrum can expand.
It took a long time, but today we have a reaction from Answers in Genesis (AIG) — the creationist ministry of Ken Ham (ol’ Hambo), the Australian entrepreneur who has become the ayatollah of Appalachia. The title is One Small Step for DNA, One Giant Leap for Man’s Brain. It was written by Elizabeth Mitchell, a creationist gynecologist.
She probably got her information from this month-old article at the BBC website: DNA clue to how humans evolved big brains. Here are some excerpts from her AIG essay, with bold font added by us for emphasis:
The human brain is triple the size of a chimpanzee’s. If we share a common ancestor, as evolutionists confidently maintain, then how did our brains leap so far ahead in size and capability? Evolutionary scientists believe they have finally found, in our DNA, the springboard for that massive evolutionary step.
We’ll skip her description of the research because we already know about it. Then she says:
So do we grow bigger brains and think greater thoughts than apes because of a genetic typographical error millions of years ago? Did a random genetic mistake in an ancient ape-like creature produce an individual with greater than the normal number of brain cells? Did that happy boo-boo get passed on through the human lineage to us because more brain is better? Ultimately, are we who we are because of a biological accident? Evolutionist Huttner would answer yes.
What else would be expected from an evolutionist? But the creationist gynecologist disagrees. She tells us:
The study’s authors lack the historical perspective available to the Bible’s Author, the Creator God. They base their contention that the single difference in the nucleotide sequence in ARHGAP11B and its chimpanzee version resulted from a mutation in an ancient common ancestor. However, differences are just differences; nothing about this difference indicates it resulted from a mutation.
BWAHAHAHAHAHA! But that wasn’t the evolutionists’ only mistake. She continues:
The authors believe the difference represents a mutation because they believe — contrary to any support from observable biology — that humans are the end product of millions of years of evolution after an ancestral divergence from the lineage shared with chimps. They search for the key that unlocked this rather amazing future for the human lineage only because of their belief in our imaginary evolutionary past.
Yet observational science has shown no mechanism by which one kind of animal can acquire the genetic information to evolve into a new, more complex kind of creature. More specifically, observational science has shown no way that humans could evolve from an ape-like creature. And even if the differences were attributable to mutations, mutations cannot create the sort of new genetic information needed for evolution into new, more complex creatures. Mutations are not the engine of evolution.
Those evolutionists are fools! Let’s read on:
So what are we to make of this discovery about ARHGAP11B? Are we humans much more like apes than we care to admit? Again, no, not at all!
Huttner’s team has discovered nothing to support the false claim that humans evolved from ape-like ancestors. They may well, however, have discovered one of God’s great designs — a genetic adjustment by which our Creator used a common design to do far greater things in the human brain than He did moments before in the ape brain on Day Six of Creation Week.
So there you are, dear reader. The evolutionists were so blinded by their godless science that they missed the significance of their discovery.
