Scientists say evolution explains why dogs enjoy meat and bones

Our fellow canines, it seems, have always been lovers of devouring meat and bones, as the National University of Columbia has recently discovered. The news has just been announced in the UK and this discovery outlines the reasons why dogs adore meat and bones as part of their diet. This breakthrough analysis was focused on evolution, which assists us in understanding how our dogs have matured and why they do what they do.

Dr. Joao Munoz-Doran unveiled this information to the world, as he attended the First Joint Congress based in Ottawa, Canada. The congress targeted Evolutionary Biology and, by crafting something similar to a ‘family tree’, Dr Munoz-Doran and his colleagues were able to successfully put the pieces of the jigsaw together. Their findings highlighted the connections relating to over 300 species of dog.

Speaking with members of the UK-based BBC team, Dr. Munoz-Doran said:

“We compared species with contrasting diets, classifying them as carnivores, omnivores and hypercarnivorous. Eight million years ago when there were open habitats, big prey grouped together.”

This means that the characteristics of dogs most accomplished in hunting have been passed on over time, so that strong-jawed canines with large teeth continue to live.

These findings explain why many pets around the country enjoy a treat by nibbling on a bone and Dr. Munoz-Doran also stated that the canines have tools, namely their teeth and jaws, which provide them with a good reason to chew bones. Although the strong mouth muscles have passed on through many species, the evolutionary process has resulted in today’s dogs being part of the hypercarnivorous food group.
