Arctic: Sea ice no barrier to bowhead whales mating, study suggests

There has been a significant amount of talk over the past several years regarding global warming and the melting of arctic pack ice. Bowhead whales of the Pacific and the Arctic were thought to be separated by the pack ice. When scientists looked at the genetics of each population, it was shown that they were closely related. Scientists were concerned that the loss of pack ice may have lessened the diversity among bowhead whale populations. In order to determine if this were true, the genetics of ancient bowhead whales was compared to the genetics of modern bowhead whales. It was found that ancient bowhead whales also showed the same relatedness. In fact, it seems that they may all be part of the same family. Researchers theorize that whaling may have made a large enough impact on bowhead whale populations to limit the gene pool.



It is unfortunate that whaling could have made such a significant impact on bowhead whales. What is worse is that some native villages in Alaska are still allowed to hunt for them. Subsistence is completely understandable, however, when it comes to situations like these and endangered species, rules and regulations need to be more strict. Furthermore, it is inevitable that this article will fuel those who believe global warming to be a farse, and may use it as evidence to prove that melting pack ice may not be as terrible as some believe it to be.
