The History of Dogs / Why Do We Itch #Ted-EdTuesday

21 May

I have rediscovered how awesome Ted-Ed videos are and I have decided to share one or two each week on Tuesday (hence my hashtag). Check out the Ted-Ed website (LINK) to see more cool videos. Most videos average about 4 – 5 minutes in length, and you could watch them in the car on the way to school. Learn something new, hear some fun facts, and enjoy. 

Since their emergence over 200,000 years ago, modern humans have established communities all over the planet. But they didn’t do it alone. Whatever corner of the globe you find humans in today, you’re likely to find another species as well: dogs. So how did one of our oldest rivals, the wolf, evolve into man’s best friend? Learn about humanity’s first domesticated animal.

The average person experiences dozens of individual itches each day. We’ve all experienced the annoyance of an inconvenient itch — but have you ever pondered why we itch in the first place? Is there actually an evolutionary purpose to the itch, or is it simply there to annoy us? Emma Bryce digs deep into the skin to find out.
