Mon ikke du kender Aloe vera? Men ved du også, at der er hele 600 Aloe-arter?
Det startede alt sammen for 16 millioner år siden i det Sydlige Afrika. Og selv om Aloerne er endemiske arter, spredte de sig over tid langs den Afrikanske østkyst og pen række øger i det indiske ocean. Siden kom turen til Mellemøsten, hvor Aloe vera opstod som art.

Alt det og mere til fortæller Louise Isager Ahl ganske underholdende om. Ligesom hun har skrevet: ALOE VERA – en plantes rejse gennem natur- og kulturhistorien i Tidsskriftet Kulturstudier.

Og her info om: Aloe polyphylla med dens ganske særlige rosetform. Den stammer fra Drakensberg-platauet i det sydøstlige Sydafrika . Hvilket også er her, hvor de to spurvefugle: Drakensberg prinia og Drakensberg siskin lever. Disse og podcastens andre fuglelyde er (med én enkelt undtagelse) fra xeno-canto.

Tjek her, hvis du vil læse om Leonardo Fibonacci  (Leonardo af Pisa). Han levede fra 1170-1250 (ca.!) og skrev i 1225: Liber quadratorum. Her opstillede han den tal-sekvens, vi nu kalder Fibonacci-tal.

Musikken
Apocalyptic Anthem med Catalyst & Humanfobia, Moving Silence af Gotama, Sunrise on Mount Shumisen med The Gateless Gate, AcidJazz af Kevin Macleod og Brer Menuet + Don Germaine med Blue Dot Sessions.
