Wolf!
Appeared at least a million hears ago!•
Many species!•
Ancestor of modern domestic dogs!•
Widely distributed in the northern hemisphere !•
Different subspecies !•
The closest living wild relative of the domestic dog is the gray wolf ( not always gray in color, •
can have black and white in there aswell and redish fur too)!
!
Species- a discrete reproductively defined system of populations with a common evolution!
Subspecies- a geographical or morphological variant!
Subspecies can interbreed !•
!
Canid exceptions!
Coyote, wolf, and domestic dog can interbreed and produce fertile offspring!•
Wolf and coyote is uncommon to breed together!•
But dogs are more common to breed with either!•
!
Legislation!
Passed legislation which bans the purposeful attempt to have a domestic dog bred by a wolf ( in
bc)!
There fore can not advertise or sell wolf/dog hybrids!
!
Predation!
Studies have shown 50% decline in the coyote population when wolves were reintroduced!•
Wolves will prey on coyotes and dogs!•
Packs offer protection and advantage to all!•
Coyotes tend to travel allone unlike wolves!•
$or in loose packs!
!
Dog!
mtDNA studies of canids revealed!
Interbred with wolves various times!•
Since mitochondria are maternally inherited !•
Wolf mitochondria indicate a female wolf was bred by a dog!◦
likely the reverse also occurred !•
!
mtDNA studies of archaeological site canids revealed!
North america dogs probably eveolved from eursaian wolves!•
Dogs came to the americas about 12000 bp in the!•
!
Red wolf!
Hybrid of the gray wolf and coyote!•
Differentiated enough to be classified a species!•
Endangered but re-introduced !•
Eastern us!•
when dna studies came available they found that it was a hybrid!

Document Summary
The closest living wild relative of the domestic dog is the gray wolf ( not always gray in color, can have black and white in there aswell and redish fur too) Species- a discrete reproductively de ned system of populations with a common evolution. Coyote, wolf, and domestic dog can interbreed and produce fertile o spring. Wolf and coyote is uncommon to breed together. But dogs are more common to breed with either. Passed legislation which bans the purposeful attempt to have a domestic dog bred by a wolf ( in bc) There fore can not advertise or sell wolf/dog hybrids. Studies have shown 50% decline in the coyote population when wolves were reintroduced. Coyotes tend to travel allone unlike wolves or in loose packs. Wolf mitochondria indicate a female wolf was bred by a dog likely the reverse also occurred mtdna studies of archaeological site canids revealed. North america dogs probably eveolved from eursaian wolves.
