If we could talk to the animals – their language is a 'world mystery'
Whether animals have language is the nature mystery people most want solved, according to a recent poll.
Asked to choose from ten unanswered questions about the natural world, almost a third (31%) said whether animals use language was one of the issues they most wanted answered.
The second most burning question was over how the dinosaurs died out, with 29% of the 2,000 people polled putting that as one of their top queries. And more than a fifth (22%) wanted to know why cats purr.
The poll for the launch of new TV show David Attenborough's Natural Curiosities on UKTV's Eden HD channel also revealed some of the most commonly believed myths about nature.
