It's tough to say, since we can't extrapolate human behavior onto another species. What's worth noting, however, is primate-behavior experts' ability to discern Teco's actions and label them abnormal for his species.
After looking at a previous video demonstrating Teco's strong connection with a human caregiver, I was surprised to learn about changes in this youngster. In the first video, Teco didn't appear to have problems with social issues, such as maintaining eye contact. Yet, between September 2010 and now, something in Teco's development seems to have veered off course.
Could the primate's unnatural rearing or early interaction with humans be affecting his developmental trajectory? It's not clear and likely won't be for some time.
Autism spectrum disorders, limited to humans so far, affect nearly one in every 110 children, according to the Centers for Disease Control and Prevention. Because of the complexity of the condition, it's difficult to know for sure if Teco's behaviors were shaped by the same factors as children who live with signs of autism.
