Timber Wolves By: Skylar Murguia


  • Organism: Common name is Timber Wolf. Scientific name is Canis Lupus.
  • Description: Timber wolves are also known as gray wolves. They are the largest wild members of the dog family. They are well known for travelling great distances in a shot amount of time.
  • Classification: Kingdom-Animalia, Phylum-Chordata, Class-Mammalia, Order-Carnivora, Family-Canidae, Genus-Canis, Species-Artic Wolf, Northwestern Wolf, Great Plainest Wolf, Mexican Wolf, and Eastern Timber Wolf.
  • Habitat Description: They live in North America, Europe, Asia, and parts of North Africa. They live withing temperatures of -70 degrees to 120 degrees Fahrenheit in forested areas far away from human populations.
  • Geologic Time: The evolution of timber wolves occurred over a geologic time scale of 800,000 years.

Morphological and Molecular Evidence:

Closest Relatives: Coyote, Foxes, and Jackals

Coyotes and timber wolves are similar because they have high-pitched barks, have gray fur with patches of white, similar shoulder height of approximately 25 inches. Although, their mitochondrial DNA is about 0.2% different.

Foxes and timber wolves are similar because they are both animals that travel in groups and they produce howls to communicate.

Jackals and timber wolves are similar because they both belong to the canine family and are omnivores. Although, they are only 25% related to each other.

Morphological or molecular evidence shows evidence for evidence for evolution of timber wolf because it displays their form and structure along with their features.

Homologous Structures:

Comparison Organisms: Red wolves, Eastern wolves, and Plaines Wolves

Red wolves and timber wolves have similar structures because they have the same bone structures and body size.

Eastern wolves and timber wolves have similar structures because they both use their leg structures to take big paces when walking.

Plaines wolves and timber wolves have similar structures because they are both 4 limbed and have tails that point upward.

Homologous structures are similar structures that are inherited from a common ancestor. It shows evidence for evolution because it shows animals like timber wolves with 4 limbs has descended.

Vestigial Structures:

A Timber wolves only vestigial structure is the dewclaw. It is located on a canine's hind leg which is considered their fifth toe. Since it is so far up, it has no use in helping a wolf walk, run, lay down, etc.

A Vestigial Structure is an organ or part of an animal that loses it's function as the animal ages. They show evidence for evolution because they were once useful by an ancestor.

Traditional Fossils:

Recent Ancestors: Domestic Dog, Coyote, and Cape Hunting Dog

Domestic Dogs and timber wolves compare because domestic dogs are 4% more populated. These dogs are said to have originated from wolf cubs that were used to guard people over 40,000 years ago.

Coyotes and timber wolves compare because they have similar facial features and color of their fur. Many people find it difficult to tell them apart.

Cape Hunting Dogs and timber wolves compare because they are both in the Animalia kingdom and family of Canidae. They are both carnivores that are becoming more endangered year by year.

Traditional Fossils are remains of a life form that inhabited traits through its an sectors. They show evidence for evolution because they show changes in traits of species over time that were caused by change in living conditions.

Comparative Embryology:

Comparative Embryology is the comparison and contrast of embryos of different species. It provides evidence for evolution because it is found to be that embryos do different species show similarities which proves their common origin is the same.
