Australia’s Evolving Hybrid Shark

Marine biologists have for the first time observed a potential new mechanism of evolution. While cataloging sharks it was discovered that Australian Black Tipped sharks are adapting to the changing environment off the Australian East Coast through interbreeding with it’s cousin, the common Black Tipped shark. It is believed that if the changes are successful this will produce a stronger species, unlike all of Hollywood’s versions of man building a super shark nature is in charge here, and unfortunately she hasn’t integrated lasers just yet.

DNA tests have shown the hybridized version to be a mix of the Australian Black Tipped shark and the common Black Tipped shark found in other parts of the world, two distinct species of shark. While the Australian Black Tip is a tropical water shark the hybrid version has adopted its overseas cousins ability to travel into cooler waters. This will allow the new Black Tip to travel further south expanding its hunting territories and increasing the sharks chances of survival. This is evolution in action. Read the full article »»»»
