According to a ground-breaking study, gene variations associated with asthma, Alzheimer's and high cholesterol have noticeably declined in just two generations. Scientists say this effectively proves that Darwinian evolution not only exists, but is still taking place.
Comment: Genes are not destiny and can be turned off and on depending on diet and environmental exposure to toxins.
The findings, which follow an analysis of the genetic blueprints of 150,000 Britons and 60,000 Americans carried out by researchers from Columbia and Cambridge University, suggest the diseases could be "weeded out" of the human species in a few thousand years.
"It's a subtle signal, but we find genetic evidence that natural selection is happening in modern human populations," said Joseph Pickrell, an evolutionary geneticist at Columbia University and one of the study's authors, the Telegraph reported.















Comment: Too bad this set of researchers won't be around to see if their predictions come true. For a contrast see: Alzheimer's cases to triple by 2050: study
