Visitors to Bristol Zoo Gardens can now get up close and personal with a family of gorillas as their new £1 million enclosure opens this weekend.
Footage recorded nineteen years ago of an 18-month-old interacting with a gorilla at Howletts Wild Animal Park in Kent has been released.
Damian Aspinall introduced his daughter Tansy to a group of critically endangered gorillas, with the video showing her happily playing with the primates.
The video has been released to help raise awareness of the gorillas' plight and the need to return them to their natural habitat.
Scientists have discovered that gorillas are closer to humans than chimpanzees in terms of genes related to sensory perception, hearing and brain development.
The findings emerge from the first completed genetic blueprint of gorillas.
Dr Chris Tyler-Smith, senior author of the research published in the journal Nature, said: "Scientists had suggested that the rapid evolution of human hearing genes was linked to the evolution of language.
"Our results cast doubt on this, as hearing genes have evolved in gorillas at a similar rate to those in humans."
