For centuries, dogs have been used by humans to do a variety of jobs. Before the invention of gunpowder and firearms, canines were instrumental in helping hunters put food on the table and protect their family. However, the greatest and most significant impact of dog domestication was how it changed human civilization.
History is an intriguing and complicated mixture of stories passed down from generation to generation, and documented accounts preserved in paintings, sculptures, ancient writings and cave drawings. Archaeological discoveries add important information about events that took place thousands of years ago to help scientists unfold the why, where, when and how.
When we use the word “theory” it means an idea or hunch about something. In the scientific community, theory is how researchers interpret facts. During the very early years, our closest now-extinct human relative, Neanderthals, and modern humans (Homo sapiens) co-existed for a time in Europe and Asia after humans migrated from Africa into Neanderthal territory. Both used fire and tools, and were expert hunters, but Neanderthals became extinct while humans flourished. The general consensus as to why Neanderthals died out is believed to be climate change which caused changes in the environment that Neanderthals couldn’t adapt to.
