How did we evolve as humans?  Are our brains getting smaller? Did we become smarter over time, or did our definition of smartness evolve with time? Do you think wars and conflicts hindered our advancements in science and technology? Those are just a few of the many questions that crossed our minds as James Mackie and I were chatting. Join us for an episode filled with mind tickling questions, and why not pause the episode every once and a while and think about the answer that you would give to these inquiries.  We would love to hear your ideas, thoughts and opinions. So, if you would like to share your answers to any of the questions or your thoughts on our responses, then please feel free to do so by sending us a message on twitter (@thl_podcast) or use the hashtag #onequestiontoomany.
