Different theories seek to promote the perspective of explaining the Great Permian Extinction. On one side, it argues on the prevalence of a terrestrial activity that triggered the extinction of the species. This occurred in the Deccan Traps around 64-65 million years ago and provided a possible explanation to the extinction of species. Similarly, proponents also pointed out the existence of climate change and the formation of new lands that has brought about the extinction of living species during the Permian Period.
On the other hand, another perspective asserts the occurrence of impact of an extra-terrestrial object (asteroid-sized) that contributed to the annihilation of the species during this period. Here, L.W. Alvarez provided specific evidences found that dates back during the Permian period and sought to explain the existence of these as justifications for such reactions and outcome.
Arguing on whose author presented the best evidence to highlight these, it can be seen that the terrestrial activity may have seen to provide more concrete evidence that volcanic eruption and associated activities within the environment after such created a huge impact towards the extinction of creatures using during the Great Permian Period. Here, specific records of change within the climate brought about by volcanic eruptions can be seen. These then contributed to the formulation and development of greenhouse gases resulting to global warming and ultimately Ice Age.
Such analogy then creates a good pattern in explaining the different stages towards the extinction of life during the Great Permian period. At the same time, the existence of these changes can be seen and studied from the perspective of how land formed and changed the habitat and conditions among these creatures. In essence, the root cause corresponded to the limited ability to survive and address these changes accordingly.
On the other hand, the argument provided by L.W. Alvarez seem to hold ground in its ability to establish the claim that an extra-terrestrial object may have caused the extinction during the Great Permian Period. This can be seen since there are available remnants to be studied that dates back to this period. At the same time, by utilizing evidences such as boundary clay, microtektites, and shocked quarts, the theorists were able to assert that indeed an impact occurred during this specific age.
However, the main critique surrounding this revolves around the inability of the specific evidences to point out the real time-frame of when the impact occurred. It may be true that the existence of such evidences have established the reality that such incident happened however there are no apparent methods that have been pointed out that directly relates it with what happened during the extinction during the Great Permian Period.
Given these ideas, I support the claim of the terrestrial explanation in explaining the extinction of creatures and marine life at the Great Permian Period. The main reason for this is that the timeline and existence of evidence are not just circumstantial like that of the extra-terrestrial perspective. Rather, it justifies the continued manifestation of how changes within the environment affected the ability of these animals to survive. At the same time, it correlates with the existence of Pangaea, global warming, and Ice Age. All these have been recorded as essential parts of the Earths development through time and manifested with the continued volcanic activity happening in different locations. Though there are still loopholes in the analysis, for my part it is considerable justification to highlight how they had been significant towards explaining the limited capacity of creatures to adjust leading to mass extinction of different species.
