Healthy human cells have two (diploid) sets of chromosomes. However, it may also happens that cells have a tetraploid (quadruple) set. Usually, they do not divide further and die, but some cells can escape this fate. An international ...

New mutations occur at increasing rates in the mitochondrial genomes of developing egg cells in aging rhesus monkeys, but the increases appear to plateau at a certain age and are not as large as those seen in non-reproductive ...

Like disease in humans, parasites can wage a deadly evolutionary "arms race" against their hosts, even driving small populations to extinction if they mutate more quickly and gain the upper hand.

More than 50 years ago on the shoreline of a rocky tide pool, the US ecologist Robert Paine discovered that the removal of a single species from an ecosystem could dramatically alter its structure and function. He had discovered ...

In the face of natural selection, genetic mutations set some individuals up for success. A single change to the sequence of a gene can give an organism an advantage—and if that mutation is passed to future generations, ...
