A survival expert says the four children who lasted 40 days in an unforgiving Colombian jungle is a testament to human endurance.

The siblings aged thirteen, nine, four, and one were found alive after surviving a plane crash, spending weeks living in the Amazon jungle.

The children have now been reunited with relatives after the tragedy that killed three adults, including their mother.

Survival expert Ben Logan says that this is an incredible case study.

He says as shown, humans are far more capable and robust than we think.
