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.
The grey wolf (Canis lupus), or just wolf, is a mammal of the order Carnivora, and the ancestor of the domestic dog. It is sometimes called timber wolf. A recent study found that the domestic dog is descended from wolves tamed less than 16,300 years ago south of the Yangtze River in China. There are many different wolf subspecies, such as the Arctic wolf.
