Humans are still evolving, study suggestsWow! And it gets even better!
"We find genetic evidence that natural selection is happening in modern human populations," said researcher Joseph Pickrel.
The findings -- detailed this week in the journal PLoS Biology -- suggest humans are still influenced by natural sections, as those with longer lifespans are more likely to pass along their mutation-free genes.So they discovered that if you don't have a deadly mutation, you live longer. They immediately conclude that that proves evolution via natural selection.
"It's a subtle signal, but we find genetic evidence that natural selection is happening in modern human populations," Joseph Pickrel, an evolutionary geneticist at Columbia University and the New York Genome Center, said in a news release.
Advances in genomic analysis techniques have allowed scientists to track the rise and fall of genetic signatures across large groups of people.
In the latest survey, researchers found a sharp drop in the prevalence of the ApoE4 gene, linked with Alzheimer's, among women over the age of 70. They also found a significant decrease in the frequency of the CHRNA3 gene, linked with smoking among men.
That only two genetic mutations were strongly correlated with length of lifespan suggests other variations have been purged from the population through natural selection.
"It may be that men who don't carry these harmful mutations can have more children, or that men and women who live longer can help with their grandchildren, improving their chance of survival," said Molly Przeworski, an evolutionary biologist at Columbia.
This is a tacit admission that mutations are deadly. That being the case, the mutations don't implement new organs by which evolution advances via speciation, as is the claim of Huxley's The Modern Synthesis, p47, 115 (now rejected by much of the evolution community).
This does not, as is the claim, prove natural selection, because it merely shows the effect of mutations to be a reduction in the size of the gene pool... or does it? The available gene pool for transfer to subsequent generations stops around 35 to 45 years of age in women. Those who live or die beyond that age have already participated in the gene pool, including those with genetic mutations. So there is no natural selection involved. Period. The available gene pool is still infected with the mutations. What, then did they find?
They found that mutations kill women earlier than non-mutated women, but not before they breed.
Interestingly they did NOT find any tendency toward speciation... all humans are deemed totally equal after all, and the Evolution Narrative would conflict with the Leftism Narrative. Can't have that.
