Guadeloupe Islands is an archipelago located in the Caribbean. It is part of the French overseas territory. It was first inhabited some 5,000 years ago. Christopher Columbus was the first European to see and land on this archipelago in 1493. The colonisation of this region was initiated in 1635, which led to the disappearance of the indigenous population within the next 2 decades. A new study has found that the European colonisation resulted in the mass extinction of 50-70% of the reptile population.
