The Origin of Teeth and Coffee Innovation

The video explores the origins of teeth, a topic still debated among scientists. It discusses three main hypotheses: the outside-in model, suggesting teeth evolved from fish scales; the inside-out model, proposing teeth originated in the mouth and then became scales; and the inside-and-out model, which posits that both teeth and scales evolved from a common structure. Despite various fossil evidence, the true origin remains unclear. The video is supported by Cometeer, a coffee company focused on sustainability.
