These findings have led to speculations that modern healthcare is letting harmful mutations to accumulate much faster than they would otherwise. Genetic mutations can be dangerous, often manifesting in subsequent generations. Biologists have long suspected that human genes, like those of other hominids, are particularly vulnerable to mutations. Researchers Adam Eyre-Walker of the University of Sussex, UK, and Peter Keightley of the University of Edinburgh, UK, compared the rates of mutation accumulation in humans with their closest counterparts
