Welcome to another episode of the BBC Earth Podcast; the podcast that delves deep into nature’s great mysteries and surfaces the unknown. This week we’re telling stories of the unexpected, stories which seem too astounding to be true. Journey with us to the Sahara where the sand is known to sing; deep, bassy sounds that reverberate as the millions upon millions of grains fall down the dunes. From the unknown cause of these sounds to the unknown status of a species, let us take you back to the 1930s, when the Tasmanian Tiger was confirmed “extinct”. Unlike the tiger you have pictured in your imagination, this one was more dog-like, with stripes across its back and a tail not dissimilar to that of a kangaroo. There have supposedly been 8 sightings of this creature in the last 3 years, suggesting science should not give up on it just yet… Should these stories leave you perplexed, just wait until you hear from Doug Larson who was the first to discover an ancient forest, undisturbed since deglaciation. These 700 year-old trees had never been found by humans until Doug came along.. Mind. Blown. Make sure you're subscribed so you never miss an episode and let us know what you thought of this week's episode on social media:Facebook: https://www.facebook.com/bbcearth/Instagram: https://www.instagram.com/bbcearth/Twitter: https://twitter.com/bbcearth Our GDPR privacy policy was updated on August 8, 2022.
