Why haven’t other animals been as generous as lizards in their evolotution?

Animals need to eat other animals to live but animals need to stay alive and lizards developing the ability to lose their tail is a good compromise. Lizard stays alive, bird gets yum yum tail. Lizards are the only nice animals on the planet maybe? I think so. DISCISS.

Lizards have actually mostly stayed the same for the last few epochs.


It isn't so much of a compromise as a self-preservation mechanism. I doubt lizards actually want to give up their tails to be "nice".
