Humans are no longer the only things hopping on ships, different species of animals also do this, and this impacts an island’s biodiversity. Today being economically isolated may be worst than being geographically isolated. The diversity and complexity of life on an island really isn’t all that complex, it is actually somewhat simple. It is largely based on the size and distance from other landmasses, if animals can’t travel back and forth easily it makes it hard for new species to come and make themselves a part of the place. Geography was once the key factor cross-island speciation, now due to animals having the ability to board ships and ride to new places due to trade commerce is the new key factor.
