We're all here because of mutations. Random changes in genes are what creates variety in a species, and this is what allows it to adapt to new environments and eventually evolve into completely new species. But most random ...

If the solution to a problem does not reveal itself straight away then why not let your initial guesswork evolve? That's the approach we've taken in trying to determine the mass of our galaxy by mapping the historic movement ...
