Re: Platyhystrix and dino sails

["meor hakif" <hakif@hotmail.com>]

ive been doing some reading about animal behaviour, and found out that in 
sexual selection, females tend to prefer males with the boldest 
characteristics (bigger size, brighter colors, larger sails?) . So, if 
Dimetrodon's sail was used in sexual display, wouldn't repeated selection of 
males with larger sails  lead to an exageration of that trait? And could 
this pattern of larger sails be seen in the fossil record(possibly by 
comparing fossil specimens of the same species from rock of different 
ages?)..well. its just an idea.:) meor hakif
