The red fox ranges from 18 to 36 inches and weighs between 6-30 lbs. The red fox ranges from a pale yellow to a dark red in color on top and from white to an ashy color on the underside and the tail tip is either black or white. The molars in the back are pointed and represent crushing. Red fox mating behavior is always changing and males are usually only with one females but sometimes find many female companions. Breeding occurs between December and April depending on their region, due to male spermatogenesis being in that time period. The mating is usually known from a vocal call from the male fox. Offspring range from 1-9. The red fox do not hunt in packs but a male and a female may share a den for a set time. They communicate through vocalizations, facial expressions and scents. Red Foxes are known to be omnivores eating small rodents to fruit. The red foxes use a den to protect their young from predators. Red foxes utilize a wide range of habitats including forest, tundra, prairie, desert, mountains, farmlands, and urban areas. They prefer mixed vegetation communities, such as edge habitats and mixed scrub and woodland. Red foxes are found throughout much of the northern hemisphere from the Arctic circle to Central America, the steppes of central Asia, and northern Africa. This species has the widest distribution of any canidae. Red foxes have also been introduced to Australia and the Falkland Islands. http://www.iucnredlist.org/details/23062/0 http://animaldiversity.org/accounts/Vulpes_vulpes/#geographic_range

The average length is around 100 cm and heigh to be around 75 cm. The gray wolf can weigh from 30-90 kg.Fur color of gray wolves also varies geographically, ranging from pure white in Arctic populations, to mixtures of white with gray, brown, cinnamon, and black to nearly uniform black in some color phases.The dominant pair in a grey wolf pack are the only members that breed. This pair is monogamous although, with the death of an alpha individual, a new alpha male or female will emerge and take over as the mate. The mating process is a lifelong one unless a partner dies.Gray wolf pups are born blind and deaf. They weigh approximately 0.5 kg and depend on the mother for warmth. The average lifespan of a wild gray wolf is 5 years. Gray wolves are highly social, pack-living animals. The packs range from 2-36 wolves. They hunt in packs to take down larger prey. The pack leader, usually the alpha male, is dominant over all other individuals. Rank is demonstrated by postural cues and facial expressions, such as crouching, chin touching, and rolling over to show the stomach. Vocalizations, such as howling allows pack members to communicate with each other about where they are, when they should assemble for group hunts, and to communicate with other packs about where the boundaries of their territories are. Scent marking is ordinarily only done by the alpha male, and is used for communication with other packs. Gray wolves are carnivores. The diet depends on their geographic location. Coyote and wolves are both very territorial and fight over land. The original location of the gray wolf was the northern hemisphere but has expanded to Canada, the United States, Mexico and Eurasia. Gray wolves are one of the most wide ranging land animals. They occupy a wide variety of habitats, from arctic tundra to forest, prairie, and arid landscapes.http://animaldiversity.org/accounts/Canis_lupus/#geographic_range http://www.defenders.org/gray-wolf/basic-facts

They were obviously chosen from three different branches of the taxonomy group. It shows that these organisms will generally be very similar.

Canis Dirus skull

Quanternary

10,000-130,000 years old
The teeth resembles the fact that this particular canidae was predominately a carnivoir and never ate vegetation. For most canidae in north america now they are omnivores because of the lack of carnivorous foods available

Canis Edwardii

Quanternary

1-1.5 million years old
Teeth shown are used for ripping and shearing meat, which was the common diet. The molars show mushing and grinding which is helpful for all kinds of food. Shows an adaptation for being a possible omnivore.

Canis Latrans

Quanternary
10-500000 years old
Bigger body shows that this organism could sufficiently find enough food to keep its larger body size. This bigger body size is still resembled today.

Canis familiaris

Quanternary

12-50000 years old
First of domesticated dogs, and it shows some interesting features. Larger mandible and skull resembling a wolf. Shows that dogs descended from wolves.

Osteoborus cynoides

tertiary

Known as the bone crushing dog it lived from 1.5-8 million years ago. It's small, conical shaped teeth show that had a different function. These teeth also show more enamel and alleged were used for bone crushing. They acted as a scavenger like a modern day hygena.

Canis lupus

Quanternary

42,000 years old
These teeth once again resemble the aspect of shearing and shredding meat, which shows these were carnivores. The larger head shows that this was a bigger animal and could sustain that size.

The head is a rust color flecked with white and a black spot on the chin. The Argentine gray fox has large ears and a long and bushy tail. The molars are well developed, and the carnassials are relatively short. This fox can grow up to 2 to 4 kg. Its shoulder height is 40 to 45 cm. The Argentine gray fox mates from August through September and the pups are born by October. The litter ranges from 2-6 pups. Both males and females are active in caring for the young. The lifespan is unknown but the longest life of a very similar species is known to be just under 14 years. Lycalopex griseus is nocturnal. The eating habits show to be omnivore, ranging from small animals to fruits. The Argentine gray fox likes to live in lowlands and foothills of coastal mountain ranges, plains, pampas, deserts, low open grasslands and forest edge habitats. They live on shrubby sandy soils.The Argentine gray fox is wide spread throughout Patagonia and western Argentina. It was introduced to Tierra del Fuego in 1951 to control the European rabbit. This area now has the highest population density. These foxes are also found on several small islands off the western coast of West Falkland, in Chile, southern Peru, and are believed to exist in central Peru. They live on both sides of the Andes Mountains. http://animaldiversity.org/accounts/Lycalopex_griseus/

This claw is there and can be used to lightly grab things. Besides that, it does not do much.
Digitgrade Stance: This is the stance of standing on their toes instead of their heels. This shows that dogs are meant to run because the toes are the best place for traction and grip for a dog.
Long legs: All canidae have long legs that are shaped specifically running fast and long. This helps when catching prey in an open field.
Canine tooth: Once hold of a predator, the canine tooth and elongated jaw is used to dislocate or snap the prey's neck to ensure a meal.

The key differences are between larger and smaller canidae. The larger ones take longer during development and develop to be larger. The smaller the canidae the less defined the rear leg is. The leg is usually curved sharply for larger ones but is not shown as much. This is because they can catch prey more easily, and do not have to run them down. All canidae have a live birth and most times there is a father and a mother for the babies. Most of the time, the littler is more than one and the highest being somewhere near 36. The offspring are fairly similar, but the bigger ones come out more matured, and in many instances the canidae babies are blind. http://www.mary.cc/squirrels/images/embryo.jpg

There has been some species that have gone extinct but not many. This is because most canidae are alike, and suite their environment well. They are known for their intelligence and it shows. ]]> 2017-06-01 03:10:31 UTC https://padlet.com/sc482/mm5ic6wo01rl/wish/174736567 Evolution sc482 https://padlet.com/sc482/mm5ic6wo01rl/wish/174736873 The evolution would be considered as coevolution. The biggest difference between difference species of canidae is either their size pr their habitat. Canidae range greatly from their size due to different environments changing. Their environments range from very mountainous to flat and desert like. They all have the same bone structure and use similar muscles. The teeth are all showing for shredding and grinding food, even though some are omnivores and others are carnivores. ]]> 2017-06-01 03:14:37 UTC https://padlet.com/sc482/mm5ic6wo01rl/wish/174736873 Evolutionary mechanisms sc482 https://padlet.com/sc482/mm5ic6wo01rl/wish/174737090 Isolation: Some parts of the grey wolf have gotten isolated overtime and they ended up in new areas. These new areas have different factors in them and it can change which has lead to new species.
Artificial selection: All dogs are derived from one wolf and have been changed through selective breeding. All dogs have the same ancestors but now there are some that are hypoallergenic, some that are 150 lbs and some that are 20 lbs. These dogs have all been changed through selective breeding from humans. ]]> 2017-06-01 03:17:37 UTC https://padlet.com/sc482/mm5ic6wo01rl/wish/174737090 Darwin sc482 https://padlet.com/sc482/mm5ic6wo01rl/wish/174737332 All canidae have similarities, mostly them being physical. There are ranging behavioral but they can remain similar. These all are from a descent and have been modified to fit the exact species the best. Whether it be big to fight off predators or be small due to the lower calorie intake. These are all designed to make the species the most fit for surviving. The natural selection process is stabilizing because there was not a dramatic change over a short time to make the species more fit. It has always been gradual.]]> 2017-06-01 03:21:24 UTC https://padlet.com/sc482/mm5ic6wo01rl/wish/174737332
