Normal resting heart rate. It is important to identify whether your heart rate sits within the normal range. If disease or injury weakens the heart, the organs will not receive enough blood to function normally. The United States National Institutes of Health (NIH) have published a list of normal resting heart rates.
There are currently two recognized species of wolves, the Canis lupus, or grey wolf, and the Canis rufus, or red wolf. These are two of the species that comprise the Canidae family in the Carnivora order. The red wolfâs Genus name, Canis, is Latin for dog.
Dogs and wolves are actually the same species. Their physical appearance is similar but their instincts, disposition and temperament are widely different. The gray wolf, or simply the wolf is the largest wild member of the Canidae family. The dog is the domesticated form of the gray wolf. Genetic drift studies and DNA sequencing confirm that domestic dog shares a common ancestry with the gray wolf. Eurasia and North America used to hold most of the worldâs wolf population but the numbers have begun to dwindle due to human encroachment.
