Head binding now and the past

[Anomalocaris]

There is another higher order effect.   If you keep cutting off the tail of every mouse, that means whatever survival benefit tails confer is lost to every mouse.   But every mouse still expanded energy prior to the amputation to develop the tail.  

Since this investment now garner much less return,  evolution will subtlety favor those mouse whose genes cause them to devote less energy to growing and maintaining a tail that will be cut off any way.

So, yes, even cutting off the tail of every mouse, regardless of whether the tail is long or short, will still subtlety cause the mouse to grow smaller tails over many generations.

The beauty of evolution is its principles are so simple and straight forward, and it’s actions and affects are infinitely complex and multilayered.

Nope.
