In the development of a chicken embryo can tail bones be seen that can be directly corresponding to the tail bones of a T-Rex? or to put it another way why don't chickens have a tail like T-Rex? Is there anything in the developed of chickens that can be liken to the switch in humans that has the cells that form the webbing between toes and fingers to die off with chicken tail bones?
Thank you for your time.
