There's a lot of 'old science' out there. Stuff we humans used to believe that has been de-bunked. Things like...   'humans are more complex than other species, which means we have more genes.' Before the Human Genome Project was completed in 2003, humans were estimated as having around 100,000 genes - more than any other species. Nope.  Turns out we only have between 20,000-25,000 genes. A tiny moss plant actually beats humans with 10,000 more genes than we do.  The sponge genome contains 18,000 genes, many of which are similar to people. In fact, humans and sponges share around 70 percent of their DNA. Previous generations simply did not have the same science and understanding of genes that we have now. They didn't know how much environment plays a role. "Genetic destiny" or determinism - the belief that we get what we get when we're born, and this will dictate the rest of our life... this is a belief that older generations had.    They were wrong. This includes our belief about the destiny of the brain.  In this episode, you'll find out the other two outdated systems most of us keep using that is holding us back from creating the change we hope to see. [Bonus: here's an extra science update that most people don't talk about: ALMOST ALL DINOSAURS were probably covered in feathers. The point?  We need to stay on our toes and make sure we don't keep passing on outdated thinking to the next generation :-) :-) ]
