Учените смятат, че Алцхаймерът е заложен в човешката еволюция

Alzheimer’s disease may have evolved alongside human intelligence, researchers report in a paper posted this month on BioRxiv.
The study finds evidence that 50,000 to 200,000 years ago, natural selection drove changes in six genes involved in brain development. Kun Tang, a population geneticist at the Shanghai Institutes for Biological Sciences in China who led the research, speculates that the memory disorder developed as ageing brains struggled with new metabolic demands imposed by increasing intelligence. They examined the genomes of 90 people with African, Asian or European ancestry, looking for patterns of variation driven by changes in population size and natural selection.
