Paragraph 2
Researchers did
on dogs. The dogs had to detect the
of different objects. Humans could only differentiate the temperatures by touching the
. The brain activity in the dogs showed that they knew which objects were
than others. The lead
of the study said: "Dogs are able to sense the
radiation coming from warm bodies...and they can change their
according to this signal." Scientists should now re-evaluate how
hunt. Many predators may use heat-sensing
to track or sense their
