I saw this video on public radio's Science Friday website, where they have a weekly video recommendation.
The video comes from a collection of videos at creaturecast.org that are truly amazing. Not very many directly relate to human anatomy and physiology . . . but, wow, they are fascinating. For example, a recent posting discusses how mitochondria and other erstwhile endosymbionts can play a variety of roles such as acting as lenses for simple animals. I teach the serial endosymbiosis theory (SET) in my A&P course . . . so this little factoid may help spice up that discussion.
So watch the FREE video about cell cooperation in a multicellular organism and let me know what you think!
