The Stray Dogs of Southern Africa
I am struck by how similar village dogs in southern Africa look to their cousins in Asia. Here is a picture of two dogs taken in Swaziland last week. These dogs would have looked at home in a village in rural India, Bangladesh or Thailand – in fact, anywhere across Asia. Same color, same demeanor – probably similar intelligence.

The conventional wisdom about the origin of dogs is that they were domesticated from wolves in east Asia. A few years ago, a project by Dr Carlos Bustamante of Cornell University called this hypothesis into question. Dr Bustamante and colleagues did a genetic survey of village dogs in Africa and found that they exhibited similar genetic diversity as the dogs of Asia. Now, this is a bit of a problem. According to Darwin’s theory of evolution, the most genetic diversity should be at the source of the origin of the species. So did dogs evolve simultaneously in Asia and Africa? (There are no wolves left in Africa save the Ethiopian wolf.) Or could it be that they evolved somewhere in between — such as the Middle East — and made their way to both continents? A story of canine globalization, if you will.

Good question and someone might eventually figure it out by testing various canine populations in between.
I think there is a strong chance that maritime trade had a role in this, not overland: boats have been criss-crossing the Indian Ocean for centuries to support trade. Ever heard about the Journey of Zheng He?
being on the social sabbatical program in Bangalore right now, I disagree with your comments on all dogs look alike as here are many stry dogs in black and other colors and shapes hurding in the streets.
Enjoy the rest of the porgram in South Africa and have a safe trip back.
There are black and piebald dogs here as well, I just happened to take a picture of a couple of brown strays.
Enjoy the last week in Bangalore as well. Did you check out MTRrestaurant?
MTR Restaurant? I'll be in BLR next month...tell me more. I also have to get to Mainland China this time around.
confirming Frauke's observation on the different colours.
Also, surprisingly, the barking sound differs from dog to dog.
Extremely interesting deep dive and discussion for dogs evolution topic 😉
I think it's worthwhile to mention that NovoJuris, our SAP Social Sabbatical client just adopted a small puppy from the street. We called Indi. She is so happy here now and she is a prove for the bighearted people here at NovoJuris.
Thanks, Nace. If possible, post a picture of Indi!
Hi Saswato, read this blog and you will learn about Indi
