Evolution

The existence of Dogs

Origin Article dog 1
Man’s best friend has been observed and studied for centuries. Actually, it’s no

wonder why we are so fascinated by theses creatures, if you think about all the
breeds, shapes, sizes and behaviours of domestic dogs today.

There is more than one theory that looks at the evolution of dogs. Some belief
they descend from more than one species and could be a mix of wolf, dingo and
jackal (but there’s no real evidence of this). Charles Darwin, best known for his
contributions to the science of evolution, didn’t even have an answer in his time.

Today, evidence (based on anatomy, genetics and behaviour) seems to lean
towards the belief that the dog originated only from one species which is the
grey wolf, or Canis lupus.


There are many things dogs and wolves have in common.
John Paul Scott, an
Origin Article dog 2ethologist, documented 90 behaviours of dogs in the 1960s. During that time, almost 70 of the behaviours were also observed in wolves. Later, the missing (previously considered minor) behaviours, were also believed to occur in wolves.

More recent evidence has shown that wolves, dogs and dingoes are very closely
related, more so than they are to any other members of the biological family
Canidae (dog-like mammals).

HUMAN COMPANIONS



In western Russia, near Ukraine’s border, skeletal remains most probably from domestic wolf-dogs – dating back 19 000 years – 
were excavated. In terms of shape, two of the skulls looked similar to a Siberian husky’s skull.


In central Europe, North America and the Near East, bones have also been found either with or near human bones, assumed to be their companions.

 



WHY DO DOGS GET ALONG WITH HUMANS?
Origin Article dog 4

Dogs, like humans, are not nocturnal and both species often benefit from
socialisation, especially with each other. A dog can be trained and usually
becomes and remains loyal to their owners during their lifetime (sometimes
for little reward in return).

Some dogs even see their owners and other family members as their pack,
with the home being their shared territory. Through the ages, dogs have
become domesticated by learning how to share work, food and lodging
with humans. This understanding, affection and intelligent cooperation
allowed dogs to integrate into human society.
