If you ran evolution all over again, would you get humans? How repeatable is ? This video is sponsored by @BountyBrand.
Special thanks to Prof. Richard Lenski and team for showing me around the lab - it is an honor to be able to witness and document such a historic science experiment.
Thanks to Dr Zachary Blount for the help with research and setting up the competition time-lapse, Dr Nkrumah Grant for microscope images of the long-term line cells @NkrumahGrant
Devin Lake, Kate Bellgowan, and Dr. Minako Izutsu for being part of this video. Long Live the LTEE!
