Document Summary
The arctic has not always been a harsh, icy place. In fact, it is clear that there once were lush forests and a variety of terrestrial and aquatic habitats that today are found only at much lower latitudes. For various reasons, this major change in climate over millions of years makes the. Arctic a particularly interesting place to search for fossils. It is not only marine invertebrate fossils that can be found in the arctic. Some very important transitional fossils of vertebrate groups have been discovered in the. One such example is puijila darwini, an extinct mammal that is thought to be a transitional form in the evolution of modern seals. As we just learned in the video on puijila darwini, global climate change is not a new thing, but marks major transitions in the evolution of life on our planet.
