Lost World of Fanged Frogs and Giant Rats Discovered in Papua New Guinea [Excerpts]
The scene is reminiscent of a movie: intrepid explorers pierce the wilderness and stumble upon a trove of amazing species rarely--if ever--seen before.
In this case, the explorers were a team of scientists from Britain, New Zealand, and the United States who trekked down into a 1 kilometer (0.62 miles) deep and 3 kilometer (1.86 miles) wide crater in Papua New Guinea. Over the course of five weeks, the team documented at least 21 new species or sub-species, including frogs with fangs, fish, and a giant rat that may be the largest currently living.
Each of these discoveries reminds us of just how much diversity is possible within each created kind since all the land animals departed from the Ark. Much of the information in the genome of those original animals has been expressed, repressed, or lost through speciation and mutation. But the creativity shown in each kind is truly amazing.
What the team did not uncover, however, are examples of what one would expect to find according to evolution: An area such as this crater is a living laboratory for what Darwin predicted: changes from one kind into another kind.
Everything the team discovered fits with animals we’re accustomed to: birds, fish, rats, etc. Even though some of these animals have unique features, there is still no evidence of fish growing legs or salamanders sprouting mammal hair. Frogs with fangs are still frogs. In a similar fashion, creatures on the famous Galápagos Islands, though often cited as evidence of evolution, suffer this same defect (as far as evolution is concerned). Finches and tortoises, no matter the size of their beaks or the shapes of their shells, will always be finches and tortoises.
Natural selection and mutations--even in this pristine wilderness of Papua New Guinea--can do nothing more than work with existing genetic material to cause changes within each kind. In other words, don’t hold your breath for the announcement of the reptiliobird.
