Jan. 16 (UPI) -- To the surprise of scientists, wolf puppies learned to play fetch in response to verbal cues from a human researcher. The unexpected phenomenon was described this week in the journal iScience. Dogs are thought to be unique in their propensity to interpret and respond to human cues, but while testing and observing the behavior of wolf pups, researchers were surprised to find the untrained puppies spontaneously retrieved a ball in response to verbal commands. "I watched the test in real time from another room. In the first two litters the two first years of the study, none of the wolves showed interest in the ball," lead researcher Christina Hansen Wheat, a behavioral ecologist at Stockholm University in Sweden, told UPI in an email. "I did not think much of it at the time...

While examining the invasive python population in Florida, researchers stumbled across the unexpected: a kind of hybrid super snake. A small number of the invasive pythons were found to be a crossbreed between two separate species, the Burmese and Indian pythons, and what's more is that this hybrid snake has the potential to thrive in new environments, according to a new study conducted by scientists with the United States Geological Survey (USGS). “We found that out of 400 Burmese pythons investigated, 13 had mitochondrial genetic signatures from the Indian python, a separate species,” Margaret Hunter, a research geneticist at USGS who led the study, told ABC News. Researchers were analyzing the tail tissue from roughly 400 Burmese pythons captured between 2001 and 2012 ...
