      Scientists have created a small robotic submarine to learn more about predators underwater. One scientist ask "how do you study an animal that lives in the entire pacific ocean?" One technique for this is to mark sharks with acoustic tags under the shark skin in which every second it transmits a "ping" of sound through the water. Scientist are going to use acoustic receivers to listen to the pings to know if the shark is near. The problem was that the receivers had a limited range and the shark was lost. They create self guide submarines to follow the shark were it goes.

  In my opinion this evidence makes this article credible because it explains in much detail how the submarine works and how each device works. There is very little information known about sharks and it is possible that they may be ding other things than just being swimming around the ocean and eating. The technology that we have today it is very easy to built the self guided submarine

     This article is about "The Vikings Were Not the First Colonizers of the Faroe islands" by Durhan University. http://www.sciencedaily.com/releases/2013/08/130820102510.htm

         There is evidence of human activity in the Faroe during at least 300-500 years ago. There was found evidence that other group of people lived there before the vikings got to the Faroes. Archaeologist found burnt peat ash from ancient humans. t is confirmed that there was human activity in the Faroes before the vikings got there, but still it is unknown were this people are form or were they came from. It is believed that Vikings destroy most of the evidence of any other humans when they colonize the islands, and that the humans that lived here stayed for sometime.

         In my opinion this evidence that has been revealed makes it credible to see that there were other humans before the Fareo were colonize. The author does give excellent evidence to this and makes you think if it is real or not. It makes you realize that there are many undiscovered things in the world and that each year something new is discovered. In which makes you believed that there is a chance that there were people in the Faroes before the vikings got there and that they lived their for some time.
