Human mutation rate has slowed recently

Researchers from Aarhus University, Denmark, and Copenhagen Zoo have discovered that the human mutation rate is significantly slower than for our closest primate relatives. This new knowledge may be important for estimates ...

Why haven't cancer cells undergone genetic meltdowns?

Cancer first develops as a single cell going rogue, with mutations that trigger aggressive growth at all costs to the health of the organism. But if cancer cells were accumulating harmful mutations faster than they could ...

Harmful genetic mutations may be less common than we thought

We are all mutants. Every characteristic that defines our species is the result of a genetic mutation somewhere in the history of evolution. And the same is true for every other organism on the planet. Yet more often than ...

Antibiotic resistance rises in 'lonely' mutating microbes

A major study led by The University of Manchester has discovered that so called 'lonely' microbes, those living at low population densities, are more likely to mutate causing higher rates of antibiotic resistance.

Just how old are animals?

The origin of animals was one of the most important events in the history of Earth. Beautifully preserved fossil embryos suggest that our oldest ancestors might have existed a little more than half a billion years ago.

Flycatcher genome sheds light on causes of mutations

A research team at Uppsala University has determined the complete genetic code of 11 members of a flycatcher pedigree. Doing this, they have for the first time been able to estimate the rate of new mutations in birds. When ...
