Hey, Great lesson on model organisms, was fun to go through all of the ones you covered and to see some of the greatest discoveries in biology and chemistry are from work on these organisms. After seeing the final model organism (mouse), I got curious if cats or dogs have been used as model organisms sometime. Just like the mouse, cats and dogs have co-habited with humans for a very long time and there are plenty of them around too. If you could shed some light on the status of Cats and dogs as model organisms in another lesson that would be fun to watch. Please make a short lesson on this topic.
good class mam.thank you
