Saved from whaling, blue whales now face threat from global warming, human activities: Study
Blue whales, facing challenges from global warming and human threats, show genetic differences among populations. Natural selection plays a role. Researchers call for conservation efforts based on their findings to protect the species. Researchers found the greatest genetic differences among the blue whale populations in the eastern Pacific, Antarctic subspecies and the pygmy subspecies of the eastern Indian and western Pacific. Blue whales average about 27 metres in length.
