The New Oldest Animal Fossils?

The video explores the early evolution of animals, focusing on the discovery of ancient sponge fossils in Canada, which may be the oldest known animal fossils. It discusses the role of oxygen levels in evolution and how early sponges might have survived in oxygen-poor environments. The video also examines the hippocampus's role in visual memory, highlighting research on mice that shows how the brain processes and stores visual sequences.
