The Cambrian explosion was one of the biggest evolutionary events in the history of life on earth. It was the start of most animal groups alive today with a diversity in shapes, sizes, and niches that has remained unparalleled. The main hypotheses proposed to explain this extreme expansion of biodiversity suggest that either the genetics of lifeforms were more flexible than they are today or the creation of too many ecological niches forced organisms to adapt to them at an alarming rate. Both cannot be ruled out to have occurred together. __________________________________________________________________ Art in Thumbnail belongs to - Danielle Dufault __________________________________________________________________ ✅ PATREON ✅ ✅ STICKERS & SHIRTS ✅ ✅Facebook: ✅Twitter: ✅Instagram: @edgeonthetrail ✅ MUSIC ✅ “EDGE Theme” - Taung Child / Reuben Cozens “La Creazione” - Di Paolo Paolacci Video di Maya “Voice of Eternity” - Keys of Moon “On the Ground” - Kevin MacLeod “Gregorian Chant” - Kevin MacLeod “Goodbye, My Homeland” - Akira Ifukub __________________________________________________________________ If I've used something on my video that you don't want me to use, PLEASE EMAIL ME first before flagging a video, I'm very reasonable and will take the video down to replace whatever image or video belongs to you.
