-The intermediate ancestor of the modern day dog is a Gray wolf.
As dogs continued to roam onto humans land, searching for food. Humans began to realize how useful the dog is.
Theories of domestication-
- By dogs being domesticated, they have become more human dependent unlike their ancestors. Now, dogs have become worse at working together as a species. In addition, dogs have lost their ability to problem solve and instead rely on humans.
-Their ancestors, especially the wolf, work together in packs and strategically hunt their game with their packs..
- Gray wolves were common throughout all of North America, but have been decimated by most of the United states by the 1930s. Gray wolves have been limited to Canada, Alaska, Great Lakes, Northern Rockies and Pacific Northwest.
-Humans have heavily impacted Gray Wolves and these wolves have to further adapt to the populous humans.
- working in packs heavily helped the wolves survive, especially against humans.
-Given the fact that the Gray Wolf is endangered because of human presence, the future may not be so bright for the Gray Wolf. As humans continue to populate, hunt and trap wolves, and take over land, the Gray Wolf will continue to decline. Unless we take action.
-It is very possible for the Gray Wolf to become extinct in the near future.
- Grassy Cross Walks to reduce Habitat fragmentation.
- More wolf reservation areas native to the gray wolf to provide a habitat to wolves without presence of humans.
