The mutations lead to small changes that over time may lead to new and likely improved species. We, as humans are but one example of this, as w ...

Biological invasions at the gene level

They further argue that since invasions are a human-related phenomenon, the ‘hadit-not-been-for-people’ reasoning is more appropriate for th ...
